Abstract:
1. A computer-assisted method for automatically discovering topics in a document collection comprising one or more documents that comprise sentences and terms, comprising: automatically dividing each of the sentences into the grammatical components of a subject and a predicate by a computer system, wherein the predicate is defined as the portion of a sentence other than the subject; assigning a first weighting coefficient to subjects in the sentences; assigning a second weighting coefficient to predicates in the sentences; tokenizing the sentences to produce a plurality of tokens, wherein each of the terms is associated with one or more of the plurality of tokens; for each one of the terms, selecting one or more terms from the terms at least in part based on the first score values of the terms; and outputting the one or more terms representing one or more topics associated with the document collection.
