A current set of context features for a database query that is associated with a string is identified. The database query includes a sequence of tokens of a database syntax, and the current set of context features includes words from the string and tokens from the database query. An inference record is selected from an inference store based on a comparison of the current set of context features to context features of inference records in the inference store. The database query is modified using a resolution of the inference record to obtain an inferred database query. The resolution includes one or more tokens of the database syntax. A search of a database is invoked using a query based on the inferred database query to obtain search results.

Natural language question answering systems

Providing a search interface for a database includes receiving string data entered via a user interface. A sequence of tokens representative of the string data is determined. Determining the sequence of tokens includes applying natural language processing to the string data. A first database query is generated in accordance with the sequence of tokens. Respective text representations for tokens in the sequence of tokens are presented via the user interface. Feedback data related to the sequence of tokens is received via the user interface. A token of the sequence of tokens is modified based on the feedback data to obtain a modified sequence of tokens. A second database query is generated based on the modified sequence of tokens. Results data are obtained from the database responsive to execution of the second database query by the database. Data based on the results data are output for presentation in the user interface.

Systems and methods for natural language question answering are described. For example, methods may include determining a set of candidate database queries, including respective sequences of tokens of a database syntax, based on a string; determining a first score for a first candidate database query from the set of candidate database queries, wherein the first score is based on a match between one or more words of the string and a token of the respective sequence of tokens of the first candidate database query; determining a second score for the first candidate database query, wherein the second score is based on natural language syntax data determined for words of the string; selecting, based on the first score and the second score, the first candidate database query from the set of candidate database queries; and invoking a search of the database using the first candidate database query to obtain search results.

Methods and apparatus are described for scoring documents in response, in part, to parameters related to the document, source, and/or cluster score. Methods and apparatus are also described for scoring a cluster in response, in part, to parameters related to documents within the cluster and/or sources corresponding to the documents within the cluster. In one embodiment, the invention may detect at least one document within the cluster; analyze a parameter corresponding to the document; and compute a cluster score based, in part, on the parameter, wherein the cluster score corresponds with at least one document within the cluster.

Methods and apparatus for ranking documents

Methods, systems, and apparatus, including computer programs encoded on computer storage media, for providing answer boxes based on query results. One of the methods includes receiving seed queries for an answer box; analyzing query log information, wherein analyzing query log information comprises identifying query results that have been provided in response to the seed queries; identifying one or more of the query results as answer box indicators based on the analyses of the query log information, wherein the answer box indicators are indicators for the answer box; and storing data identifying the one or more query results as answer box indicators for the answer box.

Providing answer boxes based on query results

A system and method for providing preferred language and/or country ordering of search results is described. A search query describing potentially retrievable information provided in a plurality of search result languages and/or countries is received. A search is executed by evaluating the search query against information characteristics maintained in a searchable data repository. At least one preferred language and/or country applicable to search results generated is dynamically determined responsive to the executed search. At least some of the search results are ordered in consideration of the at least one preferred language and/or country.

Ordering of search results based on language and/or country of the search results

A multi-stage query processing system and method enables multi-stage query scoring, including 'snippet' generation, through incremental document reconstruction facilitated by a multi-tiered mapping scheme. At one or more stages of a multi-stage query processing system a set of relevancy scores are used to select a subset of documents for presentation as an ordered list to a user. The set of relevancy scores can be derived in part from one or more sets of relevancy scores determined in prior stages of the multi-stage query processing system. In some embodiments, the multi-stage query processing system is capable of executing one or more passes on a user query, and using information from each pass to expand the user query for use in a subsequent pass to improve the relevancy of documents in the ordered list.

Multi-stage query processing system and method for use with tokenspace repository

A system identifies a document relating to a search term, where the document includes a set of structural elements. The system determines a distribution of occurrences of the search term in the document, identifies one of the structural elements based on the distribution of occurrences of the search term in the document, and presents information associated with the identified structural element.

Presentation of search results based on document structure

Web pages of a Website may be processed to improve search results. For example, information likely to pertain to more than just the Web page it is directly associated with may be identified. One or more other, related, Web pages that such information is likely to pertain to is also identified. The identified information is associated with the identified other Web page(s) and this association is saved in a way to affect a search result score of the Web page(s).

Propagating information among web pages

A system provides images or questions to multiple game participants and receives labels or answers in response thereto. The system uses the labels or answers for various data gathering purposes.
