There are two kinds of retrieval model , full text retrieval and content retrieval , and the vector space model ( vcm ) of the latter is a widely - used method with better effect . the best excellence of vcm is the predominance of knowledge presentation , which expresses documents with vectors in vector space and changes the comparability issue to the distance of vectors , and thus reduces the complexity of documents matching . however . we can not affirm the absolute effect of it , and in this thesis we prove its nonproficiency through experiments
向量空间模型最大的优点在于知识表示方法上的巨大优势，用n维空间的向量表示文档，用向量之间的夹角表示文档的相似度，从而将文档信息的匹配问题转化为向量空间中的矢量匹配问题，将难以计算的文字量化成很容易计算的实数，使问题的复杂性大大减小。但是，并不能够说目前的向量空间模型是最理想的，本文通过实验证明了vcm表达信息的不精确性。
