Abstract: There are provided methods and systems to identify an item based on data inferred from information about the item. Information is received that is descriptive of an item capable of being listed on an information storage and retrieval platform. The information is associated with an aspect-value pair, which is an aspect of the item and a value of the aspect and is inferred from the information. An expression of an interest of a user in an additional item is received. The expression is associated with the aspect-value pair. In response to the associating of the expression with the aspect-value pair, the item is identified as the additional item.

Abstract: A method and system to analyze rules is described. The system receives a query and applies a first plurality of rules to the query to identify a second plurality of rules that respectively identify at least one matching keyword in the query. Next, the system counts the first plurality of rules to identify a total quantity of rules applied to the query and further counts the second plurality of rules to identify a second quantity of rules that respectively identify at least one matching keyword in the query. Finally, the system determines a percentage of coverage for the query based on the total quantity of rules and the second quantity of rules.

Abstract: There is provided methods and systems to identify a preferred domain of a plurality of domains corresponding to a query. First, the system receives the query. Second, the system accesses demand information corresponding to the query, the demand information including navigation information associated with the query. Third, the system accesses supply information corresponding to the query, the supply information including a count of data items in each of the plurality of domains that match the query. Fourth, the system identifies the preferred domain based on the demand information and the supply information.

Abstract: There is provided methods and systems to enable navigation of data items based on aspect-value pairs extracted from the data items. First, the system receives the query. Second, the system identifies the plurality of data items found by the query. Third, the system identifies an aspect of at least one of the plurality of data items. Fourth, the system identifies a value of a plurality of values corresponding to the aspect. Fifth, the system a request to navigate to a set of data items within the plurality of data items, the request comprising the aspect and a requested value of the plurality of values. Each one of the set of data items has the aspect and the value. Sixth, the system presents, in a user interface, information about each one of the set of data items.

Abstract: There is provided methods and systems to transform unstructured information into structured information. First, the system accesses a rule specifying a condition for assigning data to the data item, the condition based on the content of the data item, the assigned data to provide structure to the data item. Second, based on a detecting that the condition has been met, the system applies the rule to assign the assigned data to the data item. Third, the system stores, in a database, the data item and the assigned data as the data item structured information.

Abstract: Methods and systems to analyze domain rules based on domain coverage of the domain rules are provided. First, the system receives a first plurality of data items from a database utilized by an information storage and retrieval platform, respectively counting the first plurality of data items to determine a total quantity of data items. Next, the system applies a plurality of rules to the first plurality of data items to identify a second plurality of data items associated with a first domain based on the respective rule, respectively counting the first plurality of data items to determine a first quantity of data items. Next, the system determines a percentage of coverage for the first domain, the percentage of coverage based on the first quantity of data items and the total quantity of data items. Next, the system represents the percentage of coverage as a first interface element within an interface.

Abstract: There are provided methods and systems to analyze rules. The system may analyze the rules by applying the rules to a most popular query. The most popular query may be identified as such by containing a particular keyword. Specifically, a most popular query may contain a keyword that appears more often than other keyword in a sample of queries received over a period of time. Next, the system applies the rules to the most popular query to determine a percentage of coverage of the rules for the most popular query. For example, a particular rule may evaluate TRUE, if the rule identifies a keyword in the query. Next the system generates a percentage of coverage based on a count of the rules that evaluated TRUE and the total number of rules that were applied to the most popular query.

The system receives a plurality of queries that are used to search a database, the plurality of queries respectively including a string of text that includes at least one keyword. Next, the system determines a subset of most popular queries from the plurality of queries. Next, the system applies a first plurality of rules to a first most popular query in the subset of most popular queries to identify a second plurality of rules that respectively identify at least one matching keyword in the first most popular query. Next, the system counts the first plurality of rules to determine a total quantity of rules and counts the second plurality of rules to determine a second quantity of rules. Next, the system determines a percentage of coverage for the first most popular query, the percentage of coverage based on the total quantity of rules and the second quantity of rules.
