Determining the Length of Textual Summarization Adaptively

With the continuing growth of the information and the information technology, many algorithms of automatically summarising texts are put forward, all of which need to predetermine the length of summarization But the number of subtopics in one document is different from that in others In order to express one document at length without any information redundance, a new algorithm to determine the length of summarization adaptively and automatically is offered Furthermore, a new module of mutual dependence is brought out By using the new algorithm and the new module, the length of summarization can be determined adaptively to different texts, the dimension of the vector space can be reduced, the computational complexity can decline, and the precision of summarization can be increased
