First Claim
Patent Images
1. A system comprising:
- a term relationship manager tangibly embodied via executable instructions stored on a computer-readable storage medium, the term relationship manager including;
an initial model generator configured to generate an initial document-term matrix based on a thesaurus;
a term representation generator configured to generate a term representation matrix based on modifying a plurality of elements of the initial document-term matrix based on antonym information associated with the plurality of elements of the initial document-term matrix, based on latent semantic analysis.

Abstract
A document-term matrix may be generated based on a corpus. A term representation matrix may be generated based on modifying a plurality of elements of the document-term matrix based on antonym information included in the corpus. Similarities may be determined based on a plurality of elements of the term representation matrix.

18. A computer program product tangibly embodied on a computer-readable storage medium and including executable code that causes at least one data processing apparatus to:
-
obtain a first term that is included in a vocabulary; determine an antonym associated with the first term, based on accessing a first polarity indicator associated with the first term in a term co-occurrence matrix and a second polarity indicator associated with the antonym in the term co-occurrence matrix. - View Dependent Claims (19, 20)
