Abstract: A search engine system assists users in locating web pages from which user-specified products can be purchased. Web pages located by a crawler program are scored, based on a set of criteria, according to likelihood of including a product offering. A query server accesses an index of the scored web pages to locate pages that are both responsive to a user's search query and likely to include a product offering. In one embodiment, the responsive web pages are listed on a composite search results page together with products that satisfy the query.

Abstract: Embodiments of the present invention provide a method and system for generating an online listing, such as a yellow pages listing, that includes information about an object, such as a business, and also includes at least one image of the structure containing the object. For example, the image may be a digital image of the store front of a business taken at a street view. Additionally, a user may select an image from a plurality of images that the user perceives as being an appropriate representative image for the business. Based on votes received a default representative image may be identified that is provided in response to a request for information about the business.

Abstract: A client component runs on a user computer in conjunction with a web browser and detects errors, such as but not limited to “404: page not found” errors, in which a requested web page or other object cannot be displayed. In response to detecting the error, the client component notifies an error processing server, which uses the URL of the failed request to identify an alternate object to display. The alternate object may, for example, be (a) an object retrieved from replacement URL, or from a URL that is otherwise related to the requested object, (b) a cached version of the requested object, (c) an object retrieved from a closely matching URL found in the user's clickstream history, or (d) a dynamically generated page that includes links to one or more of the foregoing types of alternate objects. Also disclosed are methods for identifying alternate objects for a given URL.

Abstract: The present invention provides a software facility for identifying the items most relevant to a current query based on items selected in connection with similar queries. In preferred embodiments of the invention, the facility receives a query specifying one or more query terms. In response, the facility generates a query result identifying a plurality of items that satisfy the query. The facility then produces a ranking value for at least a portion of the items identified in the query result by combining the relative frequencies with which users selected that item from the query results generated from queries specifying each of the terms specified by the query. The facility identifies as most relevant those items having the highest ranking values.

Abstract: The invention comprises a computer-implemented system and method for refining the order and/or content of a list of items. In one embodiment, the amount of user activity associated with each item displayed to users in a given context is monitored, used is to generate context-specific item weights. The weights for the same item in different contexts may be different. The selection of items included in a list presented to users, as well as the order in which the items in the list are displayed, may be adjusted over time based upon the relative weights associated with the items. This allows the items generating the greatest user interest in a particular context to be presented to first, or otherwise emphasized.

Abstract: A web site system provides functionality for searching a repository of information, such as the World Wide Web, by including a search string at the end of a URL without any special formatting. In one embodiment, when the system receives a request for a URL of the form www.domain_name/char_string, where char_string is a character string that may include spaces and non-alphabetic characters, the system initially determines whether the character string includes a prefix that identifies the URL as a non-search-request URL. If no such prefix is present, the character string is used in its entirely as a search string to execute a search, and the results of the search are returned to the user.

Abstract: A method and system are provided for collecting images of objects at geographic locations for publication in an online directory, such as online Yellow Pages. A camera and a GPS receiver, both receiving time information from a synchronized clock, are mounted on a vehicle. Time-stamped images captured by the camera and time-stamped geographic locations (e.g., longitude and latitude coordinates) determined by the GPS receiver are recorded. Each image is then associated with a geographic location based on corresponding respective time-stamps. Thereafter, each image is correlated with a street addresses based on each image's associated geographic location, for example by referring to a lookup table that correlates addresses with geographic coordinates. The address-correlated images may then be used in an online directory, where each listing (e.g., business) can be displayed with an image of an object (e.g., store front) taken at the address in the listing.

Abstract: A facility for analyzing a web page is described. The facility receives the web page. For each link occurring in the web page, if the link points to a web site previously indicated by a user as being of interest, the facility modifies the web page to identify the link as pointing to a web site of interest.

In response, the facility generates a query result identifying a plurality of items that satisfy the query. The facility then produces a ranking value for at least a portion of the items identified in the query result by combining the relative frequencies with which users selected that item from the query results generated from queries specifying each of the terms specified by the query. The facility identifies as most relevant those items having the highest ranking values.

Abstract: A grammar generation process generates a speech recognition grammar for interpreting search queries or a domain of items. The grammar comprises both single-term and multi-term utterances derived from the texts of the items (preferably the item titles). The utterances are derived in-part by expanding phrases selected from the item text into their individual terms plus all forward combinations of such terms. The forward combinations and individual terms that are deemed not useful to the search process are filtered out of the grammar. The process tends to produce a grammar containing the utterances that are most likely to occur within voice queries for the items, while maintaining a grammar size that is sufficiently small to provide reliable speech recognition.

Abstract: A search engine system displays the results of a multiple-category search according to levels of relevance of the categories to a user's search query. A query server receives a search query from a user and identifies, within each of multiple item categories, a set of items that satisfy the query. The sets of items are used to generate, for each of the multiple categories, a score that reflects a level significance or relevance of the category to the search. The scores may be based, for example, on the number of hits within each category relative to the total number of items in that category, the popularity levels of items that satisfy the query, a personal profile of the user, or a combination thereof. The categories are then presented to the user, together with the most relevant items within each category, in the order of highest to lowest category relevance.

Abstract: A search engine process predicts the correct spellings of search terms within multiple-term search queries. In one embodiment, when a user submits a multiple-term search query that includes a non-matching term and at least one matching term, a table is accessed to look up a set of terms that are “related” to the matching term or terms. A spelling comparison function is then used to determine whether any of these related terms is sufficiently similar in spelling to the non-matching term to be deemed a candidate correctly-spelled replacement. A candidate replacement term may automatically be substituted for the non-matching term, or may be suggested to the user as a replacement. The invention also includes a process for identifying terms that are related to each other based on the relatively high frequencies with which they co-occur within search queries of users, database records, and/or specific database fields.
