Application ID: 11228924

Base Claim:
1. A computer-implemented method for building an association tensor to facilitate document and word-level processing operations, the method comprising: receiving, at a computer, a collection of reference documents containing textual information; building, at the computer, the association tensor representing pair-wise similarities corresponding to a co-occurrence of term pairs in the collection of reference documents; computing a lower-dimensional vector-space representation of terms that preserves the pair-wise similarities in the association tensor based on a singular value decomposition of the association tensor; deriving a lower-dimensional vector-space representation of a document based on a weighted linear combination of computed term vectors in the lower-dimensional vector-space representation of the terms in the collection of reference documents; and performing semantic analysis upon the collection of reference documents using the lower-dimensional vector-space representation of the document.

Claim 4:
4. The method of claim 1 , wherein the collection of the reference documents is a World Wide Web (WWW) or a proprietary document collection; and wherein building the association tensor involves using a search engine to query the collection of the reference documents to determine the pair-wise similarities.
