详细介绍了模糊数学的基本原理，并附有详细的MATLAB程序，好用(Details the basic principles of fuzzy mathematics, along with a detailed MATLAB program, easy to use)

LSI就是这样一种维数约减方法。它可以通过对“文档向量矩阵”进行解奇异值分解（SVD: Singular Value Decomposition）运算，自动计算得到一个比原始空间小得多的有效语义空间(LSI is such a dimensionality reduction method. It can be through the "document vector matrix" for the singular value decomposition (SVD: Singular Value Decomposition) operation, automatically calculated an effective semantic space is much smaller than the original space)
