Claim 17:
18. An article of manufacture including a non-transitory computer program product comprising one or more computer readable storage media having stored thereon:
first program instructions executable by a computer system to cause the computer system to obtain a plurality of electronic documents relevant to a query;
second program instructions executable by the computer system to cause the computer system to obtain, via computerized term embedding, from said retrieved documents, a plurality of most similar terms with respect to said query;
third program instructions executable by the computer system to cause the computer system to, for each of said most similar terms, determine a pervasiveness score and a relevance score;
fourth program instructions executable by the computer system to cause the computer system to filter out, from said most similar terms, those of said terms that are pervasive, based on said pervasiveness score, the pervasiveness score being a probability of a given term appearing in a document related to the given term in the plurality of electronic documents relevant to the query, those of said terms that are irrelevant, based on said relevance score, the relevance score for the given term being a measure of popularity of the given term computed using a rank of documents where the given term is observed in the plurality of electronic documents relevant to the query, and those of said terms that are redundant to improve a relevance of query terms and reduce a quantity of the query terms;
fifth program instructions executable by the computer system to cause the computer system to output a top number of terms remaining in said most similar terms after said filtering, based on similarity to said query, as discriminative facets; and
sixth program instructions executable by the computer system to cause the computer system to retrieve an updated plurality of electronic documents relevant to said query by resubmitting said query with at least one of said discriminative facets.
