The Research Of Information Retrieval Algorithm In Vector Space

Technical and quick development of Internet, make Web have already become information inside the scope of world's share and one of the most outlets of the information dissemination , its text on the net originally the quantity also becomes the index number class growth . How can inspect the information that customer need to have become with by the square in extensive information ocean quickly the important research topic nowadays. Aim at the purpose of the factor- headline position characteristic item on the traditional vector space model of foundation , this thesis put forward a kind of improvement vector space model . The method can raise the search type and the text files to match the degree, then raising the Precision. It has higher recall and precision ,information retrieval system.
