BACKGROUND OF THE INVENTION1. Field of the Invention
Embodiments of this invention relate generally to search industries and, more particularly to special purpose machines, systems, methods and computer instructions for providing listings of results indicative of a hierarchical relationship.
2. Description of the Related Art
Users employ Internet searches to locate and identify information on the Internet. For example, a user may visit an Internet search-website and submit a web-search query for the keyword “shopping” in anticipation of receiving a listing of webpages or other resources related to “shopping”. These types of searches help users quickly and easily find information on the Internet.
When a user submits a web-search query, a search engine identifies search results that relate to the search query and provides the search results for display to the user. For example, upon the user submitting a web-search query for the term “shopping”, the search engine may reference an index to identify web pages that include content related to “shopping”, and provide a listing of the identified web pages for display to the user. Similar listing of results may be provided in other context, such as map-based searches, user check-in locations and the like. Unfortunately, traditional listings of results provide a limited amount of information about the displayed search results. For example, a set of search results may include a simple ranked listing that provides no indication of relationships between the search results.
SUMMARY OF THE INVENTIONVarious embodiments of methods and apparatus for providing listings of results indicative of a hierarchical relationship are provided herein. In some embodiments, provided is a computer-implemented method that includes receiving a search query, processing the search query to identify a set of search results, determining, using a computer, that the set of search results includes a parent search result corresponding to a parent entity, in response to determining that the set of search results includes a parent search result corresponding to a parent entity, identifying a set of child search results including one or more child search results that correspond to entities that are children of the parent entity, and providing a hierarchical search results list for display. The hierarchical search results list including a first listing of search results corresponding to the set of search results and a second listing of search results corresponding to the set of child search results. The second listing to be displayed in hierarchical relation to a displayed search result corresponding to the parent search result of the set of search results.
In some embodiments, provided is a computer system including one or more memories storing instructions and one or more processors coupled to the one or more memories and executing the instructions stored thereon in order to perform the following steps: receiving a search query, processing the search query to identify a set of search results, determining that the set of search results includes a parent search result corresponding to a parent entity, in response to determining that the set of search results includes a parent search result corresponding to a parent entity, identifying a set of child search results including one or more child search results that correspond to entities that are children of the parent entity, and providing a hierarchical search results list for display. The hierarchical search results list including a first listing of search results corresponding to the set of search results and a second listing of search results corresponding to the set of child search results. The second listing to be displayed in hierarchical relation to a displayed search result corresponding to the parent search result of the set of search results.
In some embodiments, provided is a non-transitory computer readable storage medium having computer-executable program instructions stored thereon that are executable by a computer to cause receiving a search query, processing the search query to identify a set of search results, determining that the set of search results includes a parent search result corresponding to a parent entity, in response to determining that the set of search results includes a parent search result corresponding to a parent entity, identifying a set of child search results including one or more child search results that correspond to entities that are children of the parent entity, and providing a hierarchical search results list for display. The hierarchical search results list including a first listing of search results corresponding to the set of search results and a second listing of search results corresponding to the set of child search results. The second listing to be displayed in hierarchical relation to a displayed search result corresponding to the parent search result of the set of search results.
As discussed in more detail below, provided are embodiments of systems and methods for identifying hierarchical relationships and displaying listings of results corresponding to the hierarchical relationships identified.
In some embodiments, identifying hierarchical relationships includes identifying parent-child hierarchical relationships between various entities. For example, in the context of a shopping center and stores located within the shopping center, the shopping center and stores may be identified as having a parent-child hierarchical relationship, with the shopping center being identified as a “parent” of the stores located within the shopping center. In certain embodiments, the hierarchical relationships are determined by mining a database of entities and information associated therewith. For example, a database that includes entries relating to “The Shopping Center” and the stores located within “The Shopping Center” may be analyzed (“mined”) to identify the parent-child hierarchical relationships between “The Shopping Center” and the stores located within “The Shopping Center”. As is discussed in more detail below, in some embodiments, hierarchical relationships between entities are established based on various characteristics and features of the entities. For example, hierarchical relationships may be based on the entities' addresses, descriptors (e.g., titles/names), locations, geometries, user interactions with web pages corresponding to the entities, or the like.
In some embodiments, additional techniques are employed to assist in identifying hierarchical relationships between entities. For example, entities that are considered to be more likely to have hierarchical relationships may be grouped together, and the entities within each grouping may be compared to one another to identify hierarchical relationships between members of the grouping. For example, entities having a classification of “shopping mall” may be grouped with other entities have a classification of “store” based on a determination that entities of the classifications “shopping mall” and “store” are likely to have hierarchical relationships with one another. The grouped entities, such as those having classifications of “shopping mall” and “store” may, then, be compared to one another to identify hierarchical relationships there between. As discussed in more detail below, groupings of entities may be based on entity types/classifications, addresses, descriptors, locations, geometries, or the like. It is expected that such groupings may increase the efficiency with which hierarchical relationships are identified by at least reducing comparisons of unrelated entities. For example, groupings may eliminate the comparison of a shopping mall in California with a river in the state of New York. Accordingly, hierarchical relationships may be mined more efficiently by eliminating, or at least reducing, burdensome processing that may take place if every entity of a database were compared to every other entity of the database.
In some embodiments, a process of identifying hierarchical relationships between entities includes identifying a set of entities for comparison, grouping related entities, identifying (“mining”) hierarchical relationships between the entities of the groupings, and generating an index indicative of the hierarchical relationships identified. For example, a database of entities may be identified, the entities may be placed into groupings based on common attributes (e.g., entity types/classifications, addresses, descriptors, locations, geometries, or the like), entities within the groups may be compared to determine whether or not hierarchical relationships exists, and the database and/or a separate hierarchical index may be generated/updated to reflect the hierarchical relationships identified.
Hierarchical relationships, such as those identified using techniques described herein, may be employed for various uses including, for example, determining how listings of results are displayed to users. For example, where a set of search results includes a result for “The Shopping Center” (a parent result), the search results displayed to the user may include child search results corresponding to “Dave's Electronics”, “The Suit Store”, and other stores located within “The Shopping Center” that are displayed in an indented listing immediately below the search result for “The Shopping Center”. As a further example, where a list of results includes parent and/or child results, the list of results may be reordered such that the displayed listing of results includes the parent results listed ahead of (i.e., above) the child results. As yet another example, the hierarchical relationships may be employed for identifying child/parent content to be displayed within a webpage. For example, a place page for “The Shopping Center” may include a listing of “Dave's Electronics”, “The Suit Store”, and other stores located within “The Shopping Center”.
A parent entity may include an entity (e.g., a shopping center) having one or more other subordinate entities (e.g., stores) that are physically or logically a part of the entity. A child entity may include a subordinate entity (e.g., store) that is physically or logically a part of the parent entity (e.g., a shopping center). A given entity may be subordinate to some entities while being superior to other entities (i.e., an entity may be both of a child and a parent entity). In a child-parent hierarchy, the parent (e.g., the shopping center) may be referred to as residing at first/higher-hierarchy level, and the children (e.g., the stores located in the shopping center) may be referred to as residing at a second/lower-hierarchy level that is immediately below the hierarchical level of the parent. Similar hierarchical relationships may be provided in other contexts, such as a university (e.g., the parent) and departments within the university (e.g., the children), a department store (e.g., the parent) and departments within the department store (e.g., the children) and so forth. Hierarchical relationships can span multiple levels. For example, a grand-parent/grand-child hierarchical relationship or the like may exist between entities.
Method 100 may include identifying an entity set as depicted at block 102. In some embodiments, identifying an entity set includes identifying a collection of entities and/or data corresponding thereto. For example, identifying an entity set may include identifying a plurality of datasets of an entity database table.
Each entry 202 may include an identifier 204, a descriptor 206, a classification 208, geometry 210, a location 212, an address 214, associated children 216, associated parents 218 and/or other information related to the entity, such as a URL Address for a webpage for the entity. Identifier 204 may include a unique identifier that is used to distinguish a given entry 202 from other entries of table 200. Descriptor 206 may specify a name/title or other descriptive information associated with the corresponding entity. Classification 208 may specify or otherwise be indicative of a type/classification associated with the corresponding entity.
Entities may be assigned one or more classifications. For example, entities that corresponds to shopping malls (e.g., “The Shopping Center”, “Palo Alto Mall”, etc.) may be assigned classifications of “shopping_center”, entities that corresponds to stores (e.g., “Dave's Electronics”, “The Suit Store”, “The Clothing Connection”, etc.) may be assigned classifications of “store”, entities that corresponds universities (e.g., “The University”, “State University”, etc.) may be assigned a classification of “university”, entities that corresponds to a department within a university (e.g., “The University College of Engineering” and “State University College of Medicine”) may be assigned a classification of “university_department”, and so forth.
Geometry 210 may specify or otherwise be indicative of a geometry associated with the corresponding entity. Geometry 210 may represent a set of one or more points and/or lines defining a geometry corresponding to the entity. For example, the geometry “G1” may define a polygon corresponding to a geographic perimeter/boundary of the “Palo Alto Shopping Center”.
Location 212 may specify or otherwise be indicative of a geographic location associated with the corresponding entity. Location 212 may represent a set of geographic coordinates (e.g., longitude and latitude coordinates) or other information defining one or more geographic locations corresponding to the entity. For example, the location “L1” may define geographic coordinates corresponding to a location of the “Palo Alto Shopping Center”.
Address 214 may specify or otherwise be indicative of a physical/geographic address associated with the corresponding entity. For a given entry 202, children 216 may include a listing of one or more identifiers corresponding to entities that are children of the entity corresponding to the given entry. For a given entry 202, parents 218 may include a listing of one or more identifiers 204 corresponding to entities that are parents of the entity corresponding to the given entry. Exemplary populated listings of children 216 and parents 218 are depicted and discussed in more detail with regard to at least
Grouping:
Method 100 may include grouping entities of the entity set, as depicted at block 104. In some embodiments, grouping entities of the entity set includes identifying entities of the entity set that are considered to be more likely to have hierarchical relationships there between, and grouping those entities together. In some embodiments, groupings of entities are based on various features of the entities, such as classifications, addresses, descriptors, locations, geometries, or the like.
Grouping Based on Classification:
In some embodiments, entities are grouped together based on a predefined parent-child hierarchical relationship between classifications. A classification hierarchical relationship may identify two or more classifications of entities that should be grouped together. For example, a classification hierarchical relationship may specify “shopping_center-store” indicating that entities having a classification of “shopping_center” should be grouped with entities having a classification of “store”. In some embodiments, a classification hierarchical relationship may be defined based on classifications of entities that are likely to have a hierarchical relationship there between. For example, classification hierarchical relationship may include “shopping_center-store” based on stores being likely children of shopping centers. Other examples of classification hierarchical relationships may include “university-university_department”, “hospital-hospital_department”, “city-street” and so forth. In some embodiments, a classification hierarchical relationship may be indicative of a relationship between the specified categories. For example, the “shopping_center-store” classification hierarchical relationship may indicative of the “shopping center” being a parent classification and “store” being a child classification. Such a relationship may be referred to as a parent-child classification hierarchical relationship.
Method 300 may include grouping entities based on the classification hierarchical relationship, as depicted at block 304. In some embodiments, entities that fall in either of the parent classification or the child classification of the parent-child hierarchical relationship may be added to the same grouping. For example, with regard to the “shopping_center-store” parent-child hierarchical relationship and table 200 of
Grouping Based on Keywords of Entity Descriptors:
In some embodiments, entities are associated with a classification based on keywords or phrases in their descriptors. For example, where the classification of “shopping_center” is associated with the keywords “shopping center”, “mall”, “shopping mall”, and the like, the entities titled “Palo Alto Shopping Center”, “The Shopping Center”, “Palo Alto Mall”, “The Shopping Center Food Court” and “The Shopping Center Drive” may be associated with the classification of “shopping_center” based on each of their descriptors including the keywords “shopping center”, “mall”, and/or “shopping mall”. As a further example, where the classification of “store” is associated with the keywords “store”, “shop” and the like, the entities entitled “The Shop” and “The Suit Store” may be associated with the classification of “store” based on each of their descriptors including the keywords “store” and/or “shop”. In some embodiments, matches between descriptors (e.g., titles/names) and keywords may be based on comparisons of a normalized version of the descriptor with a normalized version of one or more keywords. For example, the descriptor of “Palo Alto Shopping Center” may be determined to include the keyword “shopping center” based on the normalized descriptor of “palo_alto_shopping_center” including the normalized keyword of “shopping_center”.
In some embodiments, the entities that are associated with a classification are grouped with entities associated with other classifications based on a classification hierarchical relationship. For example, with regard to the “shopping_center-store” classification hierarchical relationship, a grouping may include “Palo Alto Shopping Center”, “The Shopping Center”, “Palo Alto Mall”, “The Shopping Center Food Court”, “The Shopping Center Drive”, “The Shop” and/or “The Suit Store” based on each of their descriptors including keywords associated with the classifications of “shopping_center” or “store”. Similar groupings may be generated based on the other classification hierarchical relationships such as “university-university_department”, “hospital-hospital_department”, “city-street” and so forth.
Method 400 may include identifying a classification hierarchical relationship, as depicted at block 404. In some embodiments, identifying a classification hierarchical relationship is similar to that described above with regard to at least block 302 of method 300. Method 400 may include grouping entities based on the identified keywords and the classification hierarchical relationship, as depicted at block 406. For example, with regard to the “shopping_center-store” classification hierarchical relationship the “Palo Alto Shopping Center”, “The Shopping Center”, “Palo Alto Mall”, “The Shopping Center Food Court”, “The Shopping Center Drive”, “The Shop” and “The Suit Store” may be grouped together based on each of their descriptors including keywords associated with the classifications of “shopping_center” and/or “store”, as discussed above.
A set of keywords associated with a classification may be identified based on an initial set of keywords (“seed keywords”) that are associated with the classification. In some embodiments, a set of seed keywords is associated with a classification, a set of entity descriptors that contain one or more of the seed keywords are identified, and the words contained in the entity descriptors are assessed to identify other keywords that should be associated with the classification, and the other keywords are added to the set of keywords associated with the classification. Thus, for example, a small set of seed keywords associated with the classification can be used to identify an expanded set of keywords that may not have an apparent association with the classification.
In an exemplary embodiment, the keywords “hospital” and “medical center” are identified as seed keywords for the classification of “hospital”. The seed keywords may be identified based on their well-known association with hospitals and similar medical entities. A database of entities may then be assessed to identify a subset of the entities having entity descriptors that include the seed keywords “hospital” or “medical center” in their descriptor. The subset of entities may be referred to as a seed entity set. In some embodiments, the process of identifying entities with descriptors that include the seed keywords is aided by comparing normalized versions of the seed keywords and the entity descriptors. For example, the seed-keyword “hospital” may be normalized to “-hospit-” and the entity descriptor “Shriners Hospitals—Children” may be normalized to “-shriner-hospit-children-”. The entity descriptor “Shriners Hospitals—Children” may be considered to include the seed keyword “hospital” based on the text of the normalized descriptor of “-shriner-hospit-children-” including the normalized text of “-hospit-”. In some embodiments, a seed entity set is generated for each of the seed keywords. For example, a first seed entity set may be generated that includes entities having the term “hospital” in their descriptor and a first seed entity set may be generated that includes entities having the term “medical center” in their descriptor. Each of the seed entity sets may be assessed to identify other keywords that occur in the descriptors of the entities of the seed entity sets. In some embodiments, the descriptors of the entities of a given seed entity set may be processed to generate a seed keyword list that includes all of the words/phrases contained in the descriptors of the entities of the given seed-entity-set.
In some embodiments, the seed-keyword-list includes N-grams (e.g., uni-grams, bi-grams and tri-grams) indicative of all combinations of one, two or three consecutive words in the descriptors. For example, the entity descriptor “Shriners Hospitals—Children” may be broken into the uni-grams “Shriners”, “Hospitals” and “Children”, the bi-grams “Shriners Hospitals” and “Hospitals Children”, and the tri-gram “Shriners Hospitals Children”. The seed keyword list for a given seed entity set may include some or all of the N-grams contained in all of the descriptors of the entities of the seed entity set. In some embodiments, certain words/phrases are filtered/removed from the seed-keyword-list. For example, common words and/or phrases, such as “a”, “and”, “the”, and so forth, may be excluded/removed from the seed keywords list using a stop-word list or tf-idf filtering technique.
In some embodiments, the words/phrases/n-grams of a seed-keyword-list may be ranked based on the number of times they appear in the seed-keyword-list. For example, a word/phrase/n-gram that occurs ten times in the seed-keyword-list may be ranked above a word/phrase/n-gram that occurs nine times in the seed-keyword-list, and so forth. In some embodiments, a count for an N-gram may be associated with a normalized version of the given N-gram having the highest number of occurrences. For example where the normalized text “medical center” occurs one hundred fifty times and the text “medical centers” occurs sixty times in a seed keyword set, such that the stemmed N-gram “-medic-center-” occurs a total of two hundred ten times in the seed keyword set, a count of two hundred ten may be associated with “medical center” as it is the normalized text having the highest number of occurrences. In some embodiments, a filtered/ranked seed keyword list is subjected to manual review. Such review may enable a person to manually review and remove words/phrases from the seed-keyword-list.
In some embodiments, a ranked/filtered seed keyword list is generated for each of the seed keywords. For example, a ranked/filtered seed keyword list may be generated for each of “hospital”, “medical center”, “hotel”, “motel” and so forth. In some embodiments, seed keyword lists corresponding to seed keywords that are associated with a given classification are merged into a single expanded seed keyword list that is associated with the given classification. For example, where the classification of “hospital” is associated with the seed keywords “hospital” and “medical center”, the ranked/filtered seed keyword list for the seed keyword “hospital” may be merged/combined with the ranked/filtered seed keyword list for the seed keyword “medical center” to generate a single expanded seed keyword list for the classification of “hospital”. As a further example, where the classification of hospital “hotel” is associated with the seed keywords “hotel” and “motel”, the ranked/filtered seed keyword list for the seed keyword “hotel” may be merged with the ranked/filtered seed keyword list for the seed keyword “motel” to generate a single expanded seed keyword list for the classification of “hotel”. Accordingly, a comprehensive listing of words/phrases associated with a given classification can be generated based on a relatively small number of seed keywords initially identified as being associated with the classification.
Grouping Based on Address:
In some embodiments, grouping entities includes grouping entities based on addresses. For example, entities having the same or similar address may be grouped together. In some embodiments, the addresses used for comparisons may include normalized addresses. For example, “The Shopping Center”, “Dave's Electronics”, “The Suit Store”, “ABC Department Store” and “The Shopping Center Food Court” may be grouped together based on each of the entities having an address in table 200 that corresponds to the normalized address of “1-the_shopping_center-palo_alto-ca-94034-us”.
Method 500 may include grouping entities based on normalized addresses, as depicted at block 504. Grouping entities based on normalized addresses may include adding entities with the same or similar normalized addresses to the same group. For example, “The Shopping Center”, “Dave's Electronics”, “The Suit Store”, “ABC Department Store” and “The Shopping Center Food Court” may be grouped together based on each of the entities have the same normalized address of “1-the_shopping_center-palo_alto-ca-94034-us”.
Grouping Based on Candidate Parent Entity:
In some embodiments, grouping entities includes identifying candidate parent entities and grouping candidate child entities with one or more corresponding parent entities. Such a technique may result in groups of entities that each includes one or more candidate parent entities and one or more candidate child entities. A given entity may be identified as a candidate parent entity based on one or more characteristics of the entity (e.g., a classification, geometry, descriptor, or the like) and may be grouped with other entities having characteristics indicative of them being children of the candidate parent entity (e.g., a descriptor that includes the descriptor of the candidate parent entity, a location proximate to the location of the candidate parent entity, a location contained by a geometry of the candidate parent entity, or the like).
Identifying Candidate Parent Entities:
In some embodiments, candidate parent entities are identified based on characteristics of the entity, such as a classification that is associated with a parent entity (e.g., shopping center, university, hospital, or the like), a geometry that is that is associated with a parent entity (e.g., a geometry that includes a polygon/area), and/or a descriptor including keywords associated with a parent entity (e.g., “shopping center”, “mall”, “shopping mall”, and the like).
For example, each of “Palo Alto Shopping Center”, “The Shopping Center” and “Palo Alto Mall” may be identified as candidate parent entities based on their classification of “shopping_center”, each of “The University” and “State University” may be identified as candidate parent entities based on their classification of “university”, and each of “The Hospital” and “Palo Alto Hospital” may be identified as candidate parent entities based on their classification of “hospital”. In some embodiments, entities having categories that correspond to a child entity (e.g., “store”, “university_department” and so forth) are not identified as a candidate parent entity.
As a further example, where geometries “G1”, “G2”, “G4”, “G10”, “G13”, “G15” and “G18” are indicative of geometries including a polygon (e.g., representative of a geographic area), each of “Palo Alto Shopping Center”, “The Shopping Center”, “Palo Alto Mall”, “The University”, “State University”. “The Hospital” and “Palo Alto Hospital”, may be identified as candidate parent entities based on their geometries including a polygon. In some embodiments, entities having geometries that correspond to a child entity (e.g., a geographic point, a line, or the like) are not identified as a candidate parent entity.
As a further example, where the keywords/phrases of “shopping center”, “mall”, “shopping mall” are identified as being associated with a parent entity, each of “Palo Alto Shopping Center”, “The Shopping Center” and “Palo Alto Mall” may be identified as candidate parent entities based on their descriptors including the keywords “shopping center”, “mall”, or “shopping mall”.
In some embodiments, one or more entities (“candidate child entities”) are grouped with candidate parent entities based on each of the entities having characteristics indicative of a parent-child relationship between the entity and the candidate parent entity. Thus, each resulting grouping may include a candidate parent entity and one or more candidate child entities. In some embodiments, the candidate parent entity for a given grouping may be compared to each of the candidate child entities within the grouping to determine whether a hierarchical relationship exists between the candidate parent entity and any of the candidate child entities as discussed in more detail below with regard to at least method 800 of
Grouping Based on Descriptor:
In some embodiments, an entity is grouped with a candidate parent entity if the entity has a descriptor that includes the descriptor of the candidate parent entity. For example, where “The Shopping Center” is identified as a candidate parent entity, “The Shopping Center Food Court” may be grouped with “The Shopping Center” as a candidate child entity based on the descriptor “The Shopping Center Food Court” including the substring of “The Shopping Center”. As a further example, candidate child entities titled “The University College of Engineering” and “Admissions Office: The University” may be grouped with candidate parent entity “The University” based on their descriptors including the substring of “The University”. In some embodiments, the descriptors used for comparisons include normalized descriptors. For example, “The Shopping Center Food Court” may be grouped with “The Shopping Center” based on its normalized descriptor “the_shopping_center_food_court” including the substring “the_shopping_center”.
In some embodiments, entities are matched to candidate parent entity descriptors based on prefix matching. For example, the candidate descriptor string “The University College of Engineering” may be matched to the descriptor string “The University” based on the prefix of the candidate descriptor string (i.e., the beginning of the descriptor string) including the substring of “The University”. In some embodiments, entities are matched to parent entity descriptors based on suffix matching. For example, the candidate descriptor string “Admissions Office: The University” may be matched to the descriptor string “The University” based on the suffix of the candidate descriptor string (i.e., the end of the descriptor sting) including the substring “The University”. In some embodiments, a candidate descriptor string is matched to the descriptor string having the longest match (e.g., the greatest number of matching words or characters). For example, where candidate parent entities include “The University” and “The University College”, the candidate descriptor string “The University College of Engineering” may be matched to “The University College” based on the match including three words (or twenty-two characters/spaces) as opposed to two words (or thirteen characters/spaces) that match with “The University”. As a result, the “The University College of Engineering” may be grouped with candidate parent entity of “The University College” and may not be grouped with the candidate parent entity of “The University”. In some embodiments, the comparisons may be based on the normalized versions of the descriptors.
Grouping Based on Descriptor/Address:
In some embodiments, an entity is grouped with a candidate parent entity if the entity has an address that includes the descriptor of the candidate parent entity. For example, where “The Shopping Center” is identified as a candidate parent entity, “The Shopping Center Food Court” may be grouped with “The Shopping Center” based on its address of “1 The Shopping Center, Palo Alto, Calif. 94034, US” including the substring “The Shopping Center”. In some embodiments the comparisons may be based on the normalized versions of the descriptors and address.
Grouping Based on Proximity (e.g., Distance/Radius):
In some embodiments, grouping entities includes grouping entities that are geographical proximate to one another. For example, two or more entities that are close to one another may be grouped together. In some embodiments, an entity is grouped with a candidate parent entity if the entity has a location that is within a threshold distance (e.g., radius) of the candidate parent entity. For example, referring to
Grouping Based on Polygon Geometry:
In some embodiments, an entity is grouped with a candidate parent entity if the entity has a location that is within a geographic area (e.g., a polygon) associated with the candidate parent entity. For example, referring again to
In some embodiments, any combination of two or more of the above described techniques may be employed. For example, a candidate parent entity may be grouped with other entities having a descriptor that includes the descriptor of the candidate parent entity, having an address that includes the descriptor of the candidate parent entity, having a location that is within a threshold distance (e.g., a radius) of the candidate parent entity, and/or having a location that is within a geometry (e.g., a polygon) associated with the candidate parent entity.
Method 700 may include grouping candidate parent entities with candidate child entities, as depicted at block 704. In some embodiments, a candidate parent entity is grouped with other entities having a descriptor that includes the descriptor of the candidate parent entity, having an address that includes the descriptor of the candidate parent entity, having a location that is within a threshold distance (e.g., a radius) of the candidate parent entity, having a location that is within a geometry (e.g., a polygon) associated with the candidate parent entity, and/or the like. For example, the candidate parent entity of “The Shopping Center” may be grouped with candidate child entities of “Dave's Electronics”, “The Suit Store”, “ABC Department Store” and “The Shopping Center Food Court” based on each of the candidate child entity addresses including a substring corresponding to the descriptor of “The Shopping Center”. As a further example, “The University College of Engineering” and “Admissions Office: The University” may be grouped with candidate parent entity entitled “The University” based on each of their locations being located within a polygon associated with “The University”.
In some embodiments, the candidate parent entity for a given grouping is compared to each of the candidate child entities within the grouping to determine whether hierarchical relationships exist there between. For example, “The Shopping Center” may be compared to each of “Dave's Electronics”, “The Suit Store”, “ABC Department Store” and “The Shopping Center Food Court” to determine whether hierarchical relationships exists there between. Where multiple groupings including two or more entities are identified, comparisons may be provided for each of the groupings such that hierarchical relationships between entities within each of the groupings are identified. For example, in a second grouping, “The University” may be compared to each of “The University College of Engineering” and “Admissions Office: The University” to determine whether hierarchical relationships exists there between.
Hierarchical Relationship Mining:
Method 100 may include identifying hierarchical relationships between entities of the grouping, as depicted at block 106. Identifying hierarchical relationships between entities may be referred to as “hierarchical relationship mining”. As a result of hierarchical relationship mining, a parent-child relationship may be identified between two or more entities. For example, hierarchical relationship mining may reveal that “The Shopping Center” and “Dave's Electronics” have a parent-child hierarchical relationship (i.e., “The Shopping Center” is a parent of “Dave's Electronics” and, thus, “Dave's Electronics” is a child of “The Shopping Center”). In some embodiments, hierarchical relation mining includes comparing two or more entities to one another to determine whether or not hierarchical relationships exist there between. For example, “The Shopping Center” may be compared to “Dave's Electronics” to determine whether or not a hierarchical relationship exists between the two entities.
In some embodiments, each of the entities of a database is compared to each of the other entities of the database to identify hierarchical relationships there between. In some embodiments, hierarchical relation mining includes, for each grouping of two or more entities, comparing the entities within the grouping to one another to determine whether or not hierarchical relationships exists there between. In some embodiments, where a candidate parent entity is identified, the candidate parent entity is compared to each of the candidate child entities, and the candidate child entities may or may not be compared to one another.
Method 800 may include identifying an entity group, as depicted at block 802. Identifying an entity group may include identifying one of the entity groups identified at block 104 of method 100 that has not yet been assessed/mined for hierarchal relationships.
Method 800 may include identifying an entity pair of an entity group, as depicted at block 804. Identifying an entity pair of an entity group may include identifying two entities of the grouping (identified at block 802) that have not yet been compared. For example, where group 900 is identified, in a first iteration of step 804, identifying an entity pair of an entity group may include identifying the entity pair of “The Shopping Center” and “Dave's Electronics”.
Method 800 may include determining whether a hierarchical relationship exists for the entity pair, as depicted at block 806. Determining whether a hierarchical relationship exists for the entity pair may include comparing various features/characteristics of the two entities. For example, with regard to the entity pair of “The Shopping Center” and “Dave's Electronics”, various features/characteristics of “The Shopping Center” may be compared to various features/characteristics of “Dave's Electronics”, and a hierarchical relationship, if any, between two entities may be determined based on the comparisons.
In some embodiments, a first entity may be identified as a parent of a second entity where the first entity's geometry includes a polygon and a geometry/location associated with the second entity falls within the polygon. For example, “The Shopping Center” may be identified as a parent of “Dave's Electronics” and “The Suit Store” based on geometries “G6” and “G7” and/or locations “L6” and “L7” falling within a polygon defined by geometry “G2”.
In some embodiments, a first entity may be identified as a parent of a second entity where the second entity's address contains the entity descriptor of the first entity. For example, “The Shopping Center” may be identified as a parent of “Dave's Electronics” and “The Suit Store” based on their normalized addresses of “1-the_shopping_center-palo_alto-ca-94034-us” including the string “the_shopping_center”.
In some embodiments, a first entity may be identified as a parent of a second entity where the second entity's descriptor contains the descriptor of the first entity. For example, “The Shopping Center” may be identified as a parent of “The Shopping Center Food Court” based on a normalized version of its descriptor (e.g., “the_shopping_center_food_court”) including the string “the_shopping_center”.
In some embodiments, a first entity is identified as a parent of a second entity where the first entity is associated with a higher number of impressions (e.g., is the subject of the highest number/frequency of searches and/or is displayed in the highest number/frequency of search results) than the second entity. For example, “The Shopping Center” may be identified as a parent of “Dave's Electronics” based on the string “the_shopping_center” being the subject of a higher number/frequency of user search queries and/or appearing in a higher number/frequency of search results than the string “daves_electronics”.
In some embodiments, a first entity is identified as a parent of a second entity where a descriptor of the first entity includes a keyword associated with a parent entity and the other entity does not. For example, “The Shopping Center” may be identified as a parent of “Dave's Electronics” based on “The Shopping Center” including the “parent” keyword/phrase of “shopping center” within its descriptor and “Dave's Electronics” not including a “parent” keyword/phrase within its descriptor.
In some embodiments, an identification of a hierarchical relationship between entities is based on assessment of an entity graph. An entity graph may include a plurality of nodes that each correspond to a given entity. Each node of the entity graph may include one or more node attributes that define attributes of the entity. For example, a node corresponding to the entity “The Shopping Center” may include node attributes such as an entity identifier (e.g., “The Shopping Center”), a physical address (e.g., “1 The Shopping Center, Palo Alto, Calif. 94034, US”), a geometry (e.g., “G1”) and so forth. Nodes may be connected to other nodes of the entity graph via edges/links. Each of the edges may connect two nodes and may be associated with one or more edge attributes that define a relationship between the two nodes. For example, an edge attribute may specify that one of the two nodes contains the other of the two nodes (e.g., a containment relationship). A hierarchical relationship between entities may be determined based on edge attributes corresponding to the entities. For example, it may be determined that “The Shopping Center” is a parent to “Dave's Electronics” based on an edge attribute that indicates the “The Shopping Center” contains “Dave's Electronics”.
In some embodiments, a determination of whether or not a pair of entities has a hierarchical relationship is based on single criteria or a combination of two or more criteria. For example, a hierarchical relationship between two entities may be based on application of multiple criteria and/or weighting of the criteria. Such a technique (i.e., taking into account multiple criteria) may help to provide a higher level of confidence in a determined hierarchical relationship.
In some embodiments, the determination of whether or not a parent-child hierarchal relationship exists between a given entity and the other entity being compared is based on one or more of the following exemplary scoring criteria:
-
- 1) The entity's descriptor (e.g., name/title) is contained in the address of the other entity;
- 2) The entity's descriptor is contained in the descriptor of the other entity;
- 3) The entity is associated with a higher number of impressions (e.g., the subject of a higher number/frequency of searches and/or is displayed in a higher number/frequency of search results) than the other entity; and
- 4) The entity includes a parent “keyword” in its descriptor.
Although four exemplary criteria are provided, similar techniques may be used for combinations of any type or number of criteria.
In some embodiments, for the comparison of two entities of an entity pair, each of the entities is scored based on the criteria that it satisfies. For example, where “The Shopping Center Food Court” is associated with a higher number of impression than “The Shopping Center”, “The Shopping Center Food Court” may receive a total score of “1” for satisfying the third criteria listed above and “The Shopping Center” may receive a total score of “3” for satisfying the first, second and fourth criteria listed above. In some embodiments, the entity of the entity pair that receives the highest total score is determined to be a “parent” to the other entity of the entity pair. For example, “The Shopping Center” may be identified as a parent of “The Shopping Center Food Court” based on “The Shopping Center” receiving a higher total score than “Dave's Electronics”.
In some embodiments, the criteria are weighted to generate a weighted score. For example, the first criteria may have a value of “1”, the second criteria may have a weighted value of “0.7”, the third criteria may have a weighted value of “0.4”, and the fourth criteria may have a weighted value of “0.4”. Thus, where “The Shopping Center Food Court” is associated with a higher number of impression than “The Shopping Center”, “The Shopping Center Food Court” may receive a total score of “0.4” for satisfying the third criteria and “The Shopping Center” may receive a total score of “2.1” for satisfying the first, second and fourth criteria. Accordingly, “The Shopping Center” may be identified as a parent of “The Shopping Center Food Court” based on “The Shopping Center” receiving a higher total score than “The Shopping Center Food Court”. Criteria that are more indicative of an entity being a parent may be weighted more heavily than criterion that are less indicative of an entity being a parent.
In some embodiments, an entity's total score needs to be above a threshold before it is determined that a hierarchical relationship exists. For example, an entity may be required to have a total score of “2” or greater, in addition to being greater than a total score of the other entity of the entity pair, in order for the entity to be determined to be a parent of the other entity. Such embodiment threshold may help to ensure that a sufficient amount of criteria has been met to confidently identify that a hierarchical relationship exists between the two entities. Thus, for example, where both of the entities being compared have total scores that fall below the threshold, no hierarchical relationship may be identified, regardless of which entity has a higher total score.
In some embodiments, upon identifying whether a hierarchical relationship exists for an entity pair, method 800 may include determining whether any un-assessed entity pairs remain, as depicted at block 808. In some embodiments, determining whether any un-assessed entity pairs remain includes determining whether any entity pairs of the group identified at block 802 have not yet been assessed. For example, where only the entity pair of “The Shopping Center” and “The Shopping Center Food Court” has been compared, it may be determined that at least the entity pairs of “The Shopping Center” and “Dave's Electronics”, “The Shopping Center” and “The Suit Store”, “The Shopping Center” and “ABC Department Store”, and so forth have not yet been assessed. Method 800 may include returning to block 804 to identify an entity pair (e.g., an un-assessed entity pair of group 900), such as the entity pair of “The Shopping Center” and “The Suit Store”, and conducting a determination of whether a hierarchical relationship exists there between in a manner similar to that discussed with regard to block 806. Such iterations may continue until all of the entity pairs of the group have been assessed.
Upon iterating through comparisons for all of the entity pairs of that are to be assessed for the currently identified group, method 800 may include determining whether or not an un-assessed group remains. In some embodiments, determining whether any un-assessed group remains includes determining whether any groups identified at block 104 have not yet been assessed. For example, where only group 900 has been assessed, it may be determined that at least the group including “The University”, “The University College of Engineering” and “Admissions Office: The University” has not yet been assessed, and method 900 may include returning to block 802, and providing for comparisons of the entities of “The University”, “The University College of Engineering” and “Admissions Office: The University” in a manner similar to that discussed with regard to at least blocks 804 and 806. The iterations may continue until all of the groups that are to be assessed, have been assessed. Accordingly, in some embodiments, the comparison of entity pairs may continue until each of the entity pairs of each of the identified grouping have been subject to a determination of whether or not a hierarchical relationship exists there between.
Generate Hierarchical Index:
In some embodiments, hierarchical relationships identified are stored or otherwise recorded. For example, upon identifying hierarchical relationships between entities of the grouping (e.g., as discussed with regard to at least block 106 and/or method 800), method 100 may include generating a hierarchical index indicative of the hierarchical relationships identified, as depicted at block 108 of method 100 of
With regard to at least grouping 900 of
Database table 200′ and/or hierarchical index 900 may be stored in a datastore. For example, database table 200′ and/or hierarchical index 900 may be stored in a database accessible by a server (e.g., datastore 2210 of a server 2202 discussed in more detail below with regard to at least
Displaying Results Indicative of Hierarchical Relationships:
Existing techniques for providing search results do not appear to include at least features of identifying results associated with hierarchical relationships (e.g., child/parent search results), much less providing for the display of parent and/or child results in a hierarchical manner.
Some of search results 1202 include a listing of associated terms/phrases. For example, search result 1202b includes the associated terms/phrases of “cup-of-coffee”, “no laptop”, “latte”, “great coffee”. The associated terms/phrases may include terms and phrases that are frequently used to describe the search result, and may be derived from sources across the Internet, such as reviews, web pages and other online references. The associated terms may be provided in an attempt to provide contextual information to the user, helping them to quickly identify general characteristics of the entity corresponding to the search result. For example, after seeing the term “no laptop”, a user may be able to quickly determine that the “Cafe Grumpy” does not allow the use of laptops. As depicted, the keywords may simply include an “inactive” listing of keywords that are not selectable and/or do not include hyperlinks that can be selected to navigate to a corresponding webpage).
In some instances, associated terms may happen to list an entity that is a child of an entity corresponding to the search result. For example, with regard to search result 1202a, an associated term may include “ABC Department Store”, a store that is located within “The Shopping Center”. Although the associated terms may be based on various associations with the search result, they do not appear to be derived from a hierarchical relation to the search result. For example, the term “ABC Department Store” does not appear to have been identified based on a targeted search for child/parent entities related to the “The Shopping Center”. Accordingly, a user may not be able to reliably identify any hierarchical relationship between the search result identified and the associated terms based on the displayed search results. That is, the mere presence of the associated text “ABC Department Store” does not provide a reliable indication that “ABC Department Store” is located within the “Shopping Center”.
Method 1300 may include receiving a search query, as depicted at block 1302. Receiving a search query may include a search server receiving a user search submitted via a search website. For example, a user may submit a search for “Shopping Palo Alto” via a keyword search field of a search webpage or the like.
Method 1300 may include identifying search query results, as depicted at block 1304. Identifying search query results may include searching a search engine database/index to identify a set of results that are relevant to the search query. For example, in response to a search query for “Shopping Palo Alto”, a search engine may search through entries of a search index (e.g., table 200′ or index 1100) to identify search results that correspond to “Shopping Palo Alto”. In some embodiments, a search engine may employ specific search algorithms to locate the most relevant results.
Method 1300 may include determining whether the search results include one or more parent results and/or child results, as depicted at block 1306. Determining whether the search results include a parent result and/or a child result may include assessing each of the search results to determining whether any of the search results corresponds to a parent and/or a child entity. For example, with regard to set of results 1400, each of the search results may be assessed to determine whether or not any of the search results are a parent or a child search result. It may be determined that a search result is a parent or a child search result where a corresponding hierarchical index (e.g., database table 200′ and/or hierarchal index 1100) lists at least one child and/or parent for an entity corresponding to the search result. For example, it may be determined that the search result for “The Shopping Center” is a parent search result based at least on database table 200′ and/or hierarchical index 1100 including identifiers of “N6”, “N7”, “N8” and “N9” being listed as children 216 for the entry corresponding to “The Shopping Center”. As a further example, it may be determined that the search result for “Clothing Connection” is a child search result based at least on database table 200′ and/or hierarchical index 1200 including the identifier of “N4” being listed under children 216 for the entry corresponding to “Clothing Connection”. Accordingly, it may be determined that set of search results 1400 includes a parent result and a child result based at least on the assessment of the search results corresponding to “The Shopping Center” and “Clothing Connection”. Similar assessment and determinations may be made for each of the other search results.
Where it is determined that search results do not include at least one parent or child search result, method 1300 may proceed to providing for the display of the search results for display, as depicted at block 1308. Providing search results for display may include displaying a search results webpage that includes a listing of search results corresponding to set of search results 1400. In some embodiments, the search results may be displayed in a flat listing, similar to that depicted and described with regard to
Where it is determined that the search query results do include one or more parent or child search results, method 1300 may proceed to identifying child/parent results corresponding to the one or more parent/child query results, as depicted at block 1310. Identifying child results corresponding to the parent results may include, for each parent result of the preliminary query results, identifying a set of one or more child results corresponding to the parent result. For example, “Dave's Electronics”, “The Suit Store”, “ABC Department Store”, and “The Shopping Center Food Court” may be identified as child results based at least on table 200′ and/or hierarchical index 1100 including identifiers of “N6”, “N7”, “N8” and “N9” listed as children 216 for “The Shopping Center”. In database table 200′ and hierarchical index 1500, indices corresponding to only four children are listed for “The Shopping Mall” for illustrative purposes, although any number of children may be associated with a given parent entity. For example, “The Shopping Center” may include a total of one-hundred sixty-six children corresponding to one-hundred sixty-six stores located at “The Shopping Center”. Identifying parent results corresponding to the child results may include, for each child result of the set of search results, identifying a set of one or more parent results corresponding to the child result. For example, with regard to the child result for “Clothing Connection”, “Palo Alto Mall” may be identified as a parent result based at least on table 200′ and/or hierarchical index 1100 including the identifier of “N4” being listed under children 216 for “Clothing Connection”.
In some embodiments, identifying child/parent results corresponding to the parent/child search results may include identifying a subset of child/parent entities/results that are to be provided for display in association with the parent/child search result. Where space on a webpage is limited, only a given number of the highest ranked child/parent results may be identified for display. For example, with regard to set of child results 1500, only the three highest ranked child results of “The Suit Store”, “ABC Department Store” and “Dave's Electronics”, may be identified as child results to be displayed, at least initially, in association with the parent search result for “The Shopping Center”.
Method 1300 may include generating hierarchical search results, as depicted at block 1312. In some embodiments, generating hierarchical search results may include combining the set of child and/or parent results with the set of search results to generate a set of query results including a hierarchical query result.
Method 1300 may include providing for the display of the hierarchical search results, as depicted at block 1314. In some embodiments, providing hierarchical results for display includes serving and displaying a webpage, or similar content page, that includes at least one hierarchical search result.
Search results 1702a-1702g may correspond to search results 1604a-1604g of the hierarchical set of search results 1600. In some embodiments, results may include information for an entity that corresponds to the result. For example, the search results 1602 may include a URL, an address, a phone number, business hours and the like for an entity corresponding thereto. Results may include active hyperlinks (as indicated by underlined text) that are user selectable to navigate to a webpage or similar location comprising content corresponding to the result. For example, a user may select the link “The Shopping Center” to navigate to the webpage for the “The Shopping Center” having a URL address of “www.theshoppingcenter.com”. In some embodiments, selection of a link may provide for navigation to a place-page for an entity that corresponds to the result.
In some embodiments, the results include one or more search results that are not parent or child search results (e.g., non-hierarchical search results). For example, result 1702a may correspond to “Palo Alto Shopping Center” which may not be a parent search result or a child search result.
In some embodiments, the results include one or more hierarchical search results. For example, search results 1702 include a first hierarchical search result 1704a corresponding to “The Shopping Center”. Hierarchical search result 1704a includes parent search result 1702b, and a set of child search results 1702c-1702e corresponding to “The Suit Store”, “ABC Department Store” and “Dave's Electronics”. As a further example, search results 1702 include a second hierarchical search result 1704b corresponding to “Clothing Connection”. Hierarchical search result 1704b includes a child search result 1702f and a parent search result 1702g corresponding to “Palo Alto Mall”.
In some embodiments, hierarchically related parent and child search results may be displayed in a hierarchal relationship to one another such that a user can readily identify the child-parent hierarchal relationship between the search results. For example, parent search result for “The Shopping Center” may be followed by an indented listing of child search results corresponding to “The Suit Store”, “ABC Department Store” and “Dave's Electronics”. The indented listing may be located below the parent search result for “The Shopping Center” and above the next search result for “Clothing Connection”. As a further example, child search result for “Clothing Connection” may be followed by indented parent search result corresponding to “Palo Alto Mall” indicative of an inverse-hierarchical relationship that includes the parent visually displayed below the corresponding child search result. Although the illustrated embodiment includes an indented listing, a hierarchical relationship between search results may be indicated in any suitable fashion. For example, a hierarchical relationship may be indicated via use of different fonts, font sizes, textual colors, arrangements, headings (e.g., “At The Shopping Center”) or the like.
In some embodiments, hierarchical results include only a subset of the corresponding results. For example, hierarchical search result 1704a includes only child search results 1702c-1702e (e.g., “The Suit Store”, “ABC Department Store” and “Dave's Electronics”) displayed in hierarchical association with parent search result 1702b.
In some embodiments, hierarchical results include a hyperlink to an expanded listing of results. For example, hierarchical search result 1704a may include an expansion link 1706 entitled “See More at The Shopping Center (166)”. The expansion link may be user selectable to expand the displayed listing and/or provide for navigation to a webpage, such as a place page for “The Shopping Center”, including an expanded listing of some or all of the child search results corresponding to the one-hundred and sixty-six stores at “The Shopping Center”. Webpage 1700 may include other content, such as a map corresponding to one or more of the search results, advertisements, photos and the like.
In some embodiments, hierarchical search results 1802 are the same or similar to search results 1702 and may be displayed in webpage 1800 in a manner that is the same or similar to the display of hierarchical search results 1702 of webpage 1700. For example, webpage 1800 may include search results 1802a-1802g, including hierarchical search results 1804a and 1804b displayed in a manner similar to that described above with regard to
In some embodiments, webpage 1800 includes search results 1802 displayed in a left pane of webpage 1800 and a geographic map 1806 displayed in a right pane of webpage 1800. Geographic map 1806 may include a mapping of a region corresponding to one or more of search results 1802. For example, geographic map 1806 may include a map of the geographic region containing locations of “The Shopping Center”, “The Suit Store”, “ABC Department Store”, “Dave's Electronics” and “Clothing Connection” (as indicated by corresponding pins/markers 1808 labeled “B”-“F”).
In some embodiments, map 1806 includes an interactive map that, upon user interaction with a maker 1808 corresponding to the given search result, provides an information window (e.g., bubble) corresponding to the search result. For example, upon a user hovering over, or otherwise selecting, a maker/pin corresponding to “The Shopping Center” (e.g., maker 1808 labeled “B”) with cursor 1810, bubble 1812 may be displayed. In some embodiments, a bubble may include information for the corresponding result. For example, bubble 1812 may include entity information (e.g., hyperlink, URL address, physical address, a phone number, business hours and so forth) corresponding to the “The Shopping Center”. In some embodiments, where the result corresponding to a given bubble includes a parent/child result, the bubble may include a corresponding hierarchical result. For example, bubble 1812 may include a hierarchical result 1814 corresponding to “The Shopping Center”. Hierarchical result 1814 may include information that is the same or similar to that of hieratical result 1804a. As a further example, if a user were to select maker “F” corresponding to the search result for “Clothing Connection”, a bubble may be displayed that includes content similar to that of hierarchical search result 1804b. Hierarchical results displayed in a bubble may be displayed in a hierarchal manner such that a user can readily identify a child-parent hierarchal relationship between the result and related entities/results.
Where it is determined that the entity is not a parent or child entity, method 1900 may include proceeding to displaying the content, including information about the entity, as depicted at block 1908. For example, where a marker for “The Shop” is selected a bubble may be displayed that includes a result for “The Shop” (e.g., a hyperlink to a website for “The Shop”, contact information for the shop, and so forth). Where it is determined that the entity is a parent or child entity, method 1900 may include proceeding to identifying child/parent results corresponding to the entity, as depicted at block 1910. Identifying child results corresponding to the parent results may include, identifying a set of one or more child results corresponding to the entity. For example, where a marker for “The Shop” is selected “Dave's Electronics”, “The Suit Store”, “ABC Department Store”, and “The Shopping Center Food Court” may be identified as child results based at least on table 200′ and/or hierarchical index 1100 including identifiers of “N6”, “N7”, “N8” and “N9” being listed as children 216 for the entry corresponding to “The Shopping Center”.
Method 1900 may include displaying content including a hierarchical result, as depicted at block 1912. In some embodiments, displaying content including a hierarchical result includes serving and displaying content that includes at least one hierarchical result. For example, in response to the marker for “The Shop” being selected, content for bubble 1812, including a hierarchical result for “The Shopping Center” (e.g., including a parent result for “The Shopping Center” displayed in hierarchical association with child results for “The Suit Store”, “ABC Department Store”, and “Dave's Electronics”), may be displayed as depicted in
Method 1900 may be employed in various other contexts, such as upon a user request to navigate to a place page for a given entity. For example, upon a user selection of a hyperlink for “The Shopping Center”, it may be determined that “The Shopping Center” is a parent entity, child results may be identified and a place page including a listing of the child results may be displayed.
In some embodiments, a place-page that corresponds to a parent entity includes a listing of some or all of the child or parent entities corresponding thereto. For example, place page 2000a for “The Shopping Center” may include hierarchical result 2004 including child results for “The Suit Store”, “ABC Department Store” and “Dave's Electronics”. In some embodiments, result 2004 corresponds to a set of child results identified for “The Shopping Center”.
In some embodiments, a place-page includes a hyperlink to an expanded listing of results such that a user can navigate to the expanded listing of results. For example, webpage 2000a includes a link 2106 entitled “Click here to see more at The Shopping Center (166)” that may be selected to navigate to an expanded listing of some or all of the one-hundred and sixty-six child results corresponding to the one-hundred and sixty-six stores at “The Shopping Center”. Upon selection of hyperlink 2006, listing of child search results may be expanded and/or the user may be redirected to place page 2000b of
Promoting Parent Results Ahead of Child Results:
In some embodiments, results are arranged relative to one another based on their hierarchical relationships such that results corresponding to parent entities are displayed more prominently than results corresponding to child entities (e.g., parent results listed above child results). For example, in some embodiments, where a raw listing of results includes a mix of parent results (“P”) and child results (“C”) (e.g., C, C, P, C, P, C, P), the listing of results may be reordered to generate a hierarchically ordered listing of results including the parent results listed ahead of the child results (e.g., P, P, P, C, C, C). In some embodiments, a listing of results displayed to a user may correspond to the ordering of the hierarchical arranged listing of results.
In some embodiments, a hierarchically ordered listing of results includes results of search queries. For example, a hierarchically ordered listing of results may be provided in search results webpages (e.g., similar to those of webpages
In some embodiments, a hierarchically ordered listing of results includes a listing of geographic locations that are user selectable for identifying a user's current location. For example, a listing of results may include a set of “check-in” locations, such as those provided by various location-aware mobile applications that enable a user to select and publish their current location for viewing by other users, such as friends on their social network. Notably, the acquisition of location information can be subject to user consent, and can, for example, be discarded after it is no longer needed. For example, the user may be provided with the option to share their location, and to control the accuracy and detail of what other can see.
