  4. 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

    向量空間模型最大的優點在於知識表示方法上的巨大優勢，用n維空間的向量表示文檔，用向量之間的夾角表示文檔的相似度，從而將文檔信息的匹配問題轉化為向量空間中的矢量匹配問題，將難以計算的文字量化成很容易計算的實數，使問題的復雜性大大減小。但是，並不能夠說目前的向量空間模型是最理想的，本文通過實驗證明了vcm表達信息的不精確性。
