Data Mining Technology Research Based On Vector Space Model

Data Mining is a advance international research subject of academe circle, it hassyncretized knowledge of database, artificial intelligence machinery study and statisticstheoretical knowledge . Data Mining is a course to draw the implicit, unknown information orpattern from large scale database or data warehouse which has latent value for application. Itis a new field in database research with highly applicable value, has great guidance functionto draw the decision for people in the aspects such as economic science and technology Since the information for every user to genuine needs is only a small part of vastinformation,lots of unconcerned information can disturb even flood the content that userwould be interested in. How to draw useful information fast and accurately from vastinformation resource become a problem to be solved urgently. to user, current search enginehave two insufficiency: too much unconcerned information in inquiry result, most inquirereturn hundreds of even ten thousands of information easily; the order of inquire result isconfusion; Additionally, the accuracy of inquire result 's abstract or the brief introduction( majority is the beginning part in correspondence with full text ) , the support of complexinquiry also need to be improved. This paper first introduced the concept of date mining , data mining technology and datamining algorithm that used frequently. Secondly, the paper discussed the course of textdatabase mining and text information retrieval algorithm. Then give a systemic and deeplyanalysis of vector space model . discussed the method of text document classfy and assemblybase on vector space model.base on these,we develop a small information retrieval systeminorder to search the the paper of northeast normal university.
