Determining question and answer alternatives

摘要

A computer-implemented method can include identifying one or more candidate topics from a query. The method can generate, for each candidate topic, a candidate topic-answer pair that includes both the candidate topic and an answer to the query for the candidate topic. The method can obtain search results based on the query, wherein one or more of the search results references an annotated resource. For each candidate topic-answer pair, the method can determine a score for the candidate topic-answer pair for use in determining a response to the query, based on (i) an occurrence of the candidate topic in the annotations of the resources referenced by one or more of the search results, and (ii) an occurrence of the answer in annotations of the resources referenced by the one or more search results, or in the resources referenced by the one or more search results.

1. A computer-implemented method comprising:
identifying one or more candidate topics from a query; generating, for each candidate topic, a candidate topic-answer pair that includes (i) the candidate topic, and (ii) an answer to the query for the candidate topic; obtaining search results based on the query, wherein one or more of the search results references an annotated resource, wherein an annotated resource is a resource that, based on an automated evaluation of the content of the resource, is associated with an annotation that identifies one or more likely topics associated with the resource; for each candidate topic-answer pair, determining a score for the candidate topic-answer pair based on (i) an occurrence of the candidate topic in the annotations of the resources referenced by one or more of the search results, and (ii) an occurrence of the answer in annotations of the resources referenced by the one or more search results, or in the resources referenced by the one or more search results; and determining whether to respond to the query with one or more answers from the candidate topic-answer pairs, based on the scores.
