Wide-spectrum information search engine
View Patent ↗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.
1. A method for processing information, comprising:
receiving a segmented judgment matrix, the segmented judgment matrix being a numerical matrix pairing each of a set of terms to each of a set of classifications, each term being a word or phrase, the segmented judgment matrix having a plurality of information submatrices, each element of each information submatrix representing a rating of a relevance of the term of the element to the classification of the element, each information submatrix being a numerical matrix representing the relevance of each of a subset of the set of terms to each of a subset of the set classifications;
using the segmented judgment matrix to calculate an information spectrum;
receiving a search request;
using the segmented judgment matrix to calculate an information spectrum of the search request;
using the segmented judgment matrix to calculate an information spectrum for each of a plurality of documents; and
identifying at least some documents of the plurality of documents as relevant to the search request based upon a comparison of the calculated information spectrums.
2. The method of claim 1 wherein: each information submatrix has a plurality of classifications and a plurality of terms relevant to each classification; and
using the segmented judgment matrix to calculate an information spectrum for each of a plurality of documents comprises calculating an information spectrum for each of the plurality of documents based upon at least some of the plurality of terms;
the method further comprising:
selecting the plurality of terms based upon a relevance of each term of the plurality of terms to at least some of the classifications of the information submatrices.
3. The method of claim 1 wherein the step of calculating an information spectrum for each document and for the search request further comprises determining a log average among the ratings of relevance of the terms for each classification.
4. The method of claim 1 wherein the step of identifying at least some documents further comprises determining a distance between the information spectrum of the at least some documents and the information spectrum of the search request.
5. The method of claim 1 further comprising: selecting a document of the identified documents as definitely relevant to the search request including calculating an information spectrum of the selected document; and using the calculated information spectrum of the selected document as a new search request.
6. The method of claim 1 further comprising:
zooming in on a portion of a document information spectrum; and
determining that a document and request have a wide spectrum with significant content in a field F of a term and measuring the request and document using a subengine for field F.
