The paper discusses on the influence of TFIDF indexing method on inner product and bilinear function which are fundamental for Vector Space Model; and comes to the conclusion that indexing process can change the bilinear property of inner product space. It also comes to the finding that the maximum term frequency influences vector space greatly; and that the normalization factor has both retrieval and geometrical values.
