Using Matrix Singular Value Decomposition Method to Revise a Paragraph's Keyword Vectors

When designing an automatic abstracting method using automatic clustering thought,it’s required to generate a paragraph’s keyword vectors.The precision of keyword vectors has a big influence on the effect of paragraph clustering,hence influencing that of automatic abstracting.In this paper,a method using singular value decomposition technique for revising a paragraph’s keyword vectors is given.
