Abstract:
1. A computer-implemented method, the method comprising steps of: for each target word of target words, determining a set of overcorrelated pairs of said each target word and words in a plurality of documents, wherein an overcorrelated pair occurs when said each target word and a particular word in said plurality of documents have a first actual co-occurrence in portions of said plurality of documents that exceeds an expected probabilistic co-occurrence by at least a first threshold; for said each target word of said target words and the set of the overcorrelated pairs determined for said each target word, determining overcorrelated triplets comprising said each target word and two words from said set of overcorrelated pairs, wherein an overcorrelated triplet occurs when said each target word and particular two words in said set of overcorrelated pairs have a second actual co-occurrence in said portions of said plurality of documents that exceeds said expected probabilistic co-occurrence by at least a second threshold; storing data representing the overcorrelated triplets determined for said target words on one or more storage devices; and wherein the method is performed by one or more computing devices.
