Abstract: The method, system, and computer program provides the capability to compute measurements of the similarity between portions of text based on semantic profiles of the text portions. A computer-implemented method of determining similarity between portions of text comprises generating a semantic profile for at least two portions of text, each semantic profile comprising a vector of values and computing a similarity metric representing a similarity between the at least two portions of text using the at least two generated semantic profiles. The semantic profile comprises a vector of information values.

Abstract: A method of semantic profiling of documents comprises receiving a document to be profiled, the document comprising a plurality of terms, for each of at least a portion of the plurality of terms in the document determining a part of speech and a grammatical function of the term, obtaining senses of the term, selecting a sense as a most likely meaning of the term, and calculating an information value of the term, and generating a semantic profile of the document comprising at least some of the calculated information values.
