| Title | Research of Personalized Search Technology Based on Synthetically Inversed Index |
| Abstract | With development of search engine technology, personalized search engine has being concerned by more and more people. Aiming at the actual flaw of current search engine, we do some research on the technology of personalized search engine. This paper brought up an architecture of personalized inverted index which incarnated the interests of users based on traditional inversed index. The traditional inversed index was build according to splitting word automatically to documents. The personalized synthetically inverted index was built by the information which was marked by users in the documents with user’s subjective behavior, like keywords, subjects, remark, and so on. Meanwhile, algorithms of statistical word frequency and channels and Document Attention. Algorithm were used to update the personalized synthetically inverted index. Finally, the paper designed a simple personalized search engine based on Lucene. In order to display the documents in the first place of the result which users were most interested in, the personalized inverted index was used firstly when the user used search engine. The system would continue to find another information in traditional Inversed Index until the information in the personalized inverted index could not provide enough information to the user.·The main contributions and innovations of this dissertation are as follows:·The current status and the problems of search engine, personalized search and Inversed Index.·The system of personalized document management based on keywords was presented.·Synthetically Inversed Index, algorithms of statistical word frequency and channels and Document Attention Algorithm were combined with when user used search engine.·On the basis of it, a simple system based on Lucene was designed, the system can be used to build, add and update indices, and search documents.The research and exploration of this paper provide some ideas for the further research of the personalized technique of the search engine.
