The Study of the Question of Free Indexing

自由标引问题研究

Manned indexing experiences based auto-classifying tries to solve this problem through the principle of the compactness and inter changeableness of information search languages. However, direct application of indexing phrases to match the targets causes a series of problems in the actual situations.
