Wide-spectrum information search engine

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.

CROSS REFERENCE TO RELATED APPLICATIONS[0001]This application is a continuation of U.S. application Ser. No. 10 / 800,217 filed Mar. 12, 2004, which is a continuation of U.S. application Ser. No. 10 / 315,059 filed Dec. 10, 2002, which is a continuation of U.S. application Ser. No. 09 / 305,583 filed May 5, 1999, all or which are entitled WIDE-SPECTRUM INFORMATION SEARCH ENGINE, and are all hereby incorporated by reference in their entirety for all purposes.TECHNICAL FIELD[0002]The field of the invention relates to document retrieval and more particularly to search engines operating within the context of a database.BACKGROUND OF THE INVENTION[0003]Automated methods of searching databases are generally known. For example, P. G. Ossorio developed a technique for automatically measuring the subject matter relevance of documents (Ossorio, 1964, 1966, 1968, 1969). The Ossorio technique produced a quantitative measure of the relevance of the text with regard to each of a set of distinct subject...

Problems solved by technology

As a result, the technique has certain characteristics that make it unusable for information retrieval in cases in which there is a very wide range of subject matter fields, such as the Internet.
