MULTI-STAGE QUERY PROCESSING SYSTEM AND METHOD FOR USE WITH TOKENSPACE REPOSITORY |
摘要 |
<p>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.</p> |
