Abstract: A method and computer program product for comparing documents includes segmenting a judgment matrix into a plurality of information sub-matrices where each submatrix has a plurality of classifications and a plurality of terms relevant to each classification; evaluating a relevance of each term of the plurality of terms with respect to each classification of each information submatrix of the information submatrices; calculating an information spectrum for a first document based upon at least some of the plurality of terms; calculating an information spectrum for a second document based upon at least some of the plurality of terms; and identifying the second document as relevant to the first document based upon a comparison of the calculated information spectrums.

Abstract: A method and apparatus are provided for searching for information. The method includes the step of segmenting a judgement matrix into a plurality of information sub-matrices where each submatrix has a plurality of classifications and a plurality of terms relevant to each classification. The method further includes the steps of evaluating a relevance of each term of the plurality of terms with respect to each classification of each information sub-matrix of the information sub-matrices and calculating an information spectrum for each of a plurality of documents based upon at least some of the plurality of terms. The method further includes the steps of receiving a search request, calculating an information spectrum of the search request based upon at least some of the plurality of terms and identifying at least some documents of the plurality of documents as relevant to the request based upon a comparison of the calculated information spectrums.
