Abstract
A computer-implemented method, computerized apparatus and computer program product for query performance prediction, the method comprising: obtaining a result list comprising a listing of documents retrieved from a collection in response to a query; obtaining for each of the listed documents in the result list a score indicating a measure of the document's relevance to the query; sampling the result list to obtain a plurality of sub-lists each of which comprising a listing of documents subsumed by the result list; for each of the plurality of sub-lists, analyzing scores of the documents listed therein to obtain a sample performance estimator; and estimating performance of the result list based on the sample performance estimator of each of the plurality of sub-lists.
