9-1 Performance Improvement of Document Similarities by Implementation of Characters-Code-Conversion

Abstract

Our research objective is to judge document similarities using Orthogonal Transformation. We focus on Fourier system in this paper from the results of previous experimentation. In previous experimentations, what single-byte characters and double-byte characters are intermixed was a problem. Therefore we propose the characters-code-conversion against this problem. Precision of the judge rose by the characters-code-conversion, which standardizes characters code to double-byte characters. Furthermore, we decided threshold of each length of sentences.
