    摘要： Techniques that support trail-based exploration by a user of a repository of documents are described herein. In one embodiment, trail definition data that specifies a trail is received. The trail includes an ordered series of waypoints including a trailhead, intermediate waypoints, and one or more trailends. In some embodiments, deadends may also be defined in the trial. A particular waypoint in the ordered series of waypoints is established as a current waypoint. Search terms can be received from a user to cause a search to be performed. It is then determined whether the search satisfies matching criteria associated with a waypoint that immediately follows the current waypoint in the ordered series of waypoints. If so, the user advances to the next waypoint. Otherwise, the user remains at the current waypoint. Finally, if a trailend is reached, then an action such as rewarding the user in some way may be performed.

    摘要： A system and method for deriving user intent from a query. The system includes a query engine, and an advertisement engine. The query engine receives a query from the user. The query engine analyzes the query to determine a query intent that is matched to a domain. The query may be further analyzed to derive predicate values based on the query and the domain hierarchy. The domain and associated information may then be matched to a list of advertisements. The advertisement may be assigned an ad match score based on a correlation between the query information and various listing information provided in the advertisement.

    摘要： The system includes a query engine and an advertisement engine. The query engine is configured to receive a query from the user. The advertisement engine generates advertisement results corresponding to the query. The advertisement results are selected from entries in an advertisement database, where the entries include predicate values corresponding to a domain. The advertisement engine generates a diverse advertisement result that is a subset of the database entries that match the query. The diversity result varies at least one predicate by selecting entries for the list that include a proportional representation of each available predicate value in the database that matches the query.

    摘要： A system for generating an ordered list. The system may include a query engine and an advertisement engine. The query engine receives a query from the user and determines parameters to match with the advertisement. The advertisement engine receives the parameters and generates a list of items based on the parameters. The system may function in a precompute mode to calculate intervals for each available item to minimize the variable processing costs for each item. Further, the number of intervals a crossed item may be selected in a manner to satisfy a given space constraint. By characterizing each item by a minimum price within each interval, the system can quickly query the interval matching the desired quantity for each item and determined if the minimum price for that interval is less than the top-k prices already included in the list.
