Abstract:
1. A method for searching, the method comprising: receiving, by a computer system, a query; identifying, by the computer system, a plurality of documents relevant to the query, each document of the plurality of documents having at least one facet group associated therewith such that a plurality of facet groups are associated with the plurality of documents; retrieving, by the computer system, global probabilities for the plurality of facet groups associated with the plurality of documents; combining, by the computer system, the retrieved global probabilities associated with the plurality of facet groups with a corresponding plurality of entropy values for the plurality of facet groups, each entropy value of the plurality of entropy values based on a distribution of values in the plurality of documents the facet group of the plurality of facet groups corresponding to the each entropy value; ranking, by the computer system, the plurality of facet groups according to the combining of the retrieved global probabilities and the corresponding entropy values; selecting, by the computer system, a portion of the plurality of facet groups according to the ranking; and returning, by the computer system, the plurality of documents and the portion of the facet groups.
