METHOD AND SYSTEM FOR COMPARING DOCUMENTS BASED ON DIFFERENT DOCUMENT-SIMILARITY CALCULATION METHODS USING ADAPTIVE WEIGHTING

摘要

PURPOSE: A method and a system for comparing documents based on document-similarity calculation methods which use adaptive weighting are provided to generate a combination similarity value based on document-similarity values and a weight-combination function. CONSTITUTION: A system receives a plurality of similarity values calculated in different document-similarity calculation methods(202). The system determines weighted value of each document-similarity calculating method(204). The system determines a weight-combined function(206). The system generates combination similarity(208). [Reference numerals] (202) Similarity values calculated by different document-similarity calculation methods are received; (204) Each document-similarity calculation method is determined; (206) Weight-combined function is determined; (208) Combination similarity is generated; (AA) Start; (BB) End
