Abstract


Latent Semantic Indexing (LSI) technology is a hot technology of the third-generation search engine, a personalized retrieval method. The first generation of search engines using keyword search technology based on Boolean logic, the second generation on the basis of the former through a variety of methods to improve the precision rate, and third-generation search engine by practicality and ease of use for the target use of frontier DeepWeb, artificial intelligence, semantic analysis technology. Mainstream search technology is still using the first generation technology based on Boolean logic, it is necessary for the user to provide accurate keywords for retrieval; increase in data traffic as well as the flexibility of natural language ambiguity, makes traditional search methods more and can not be competent to the needs of users. As an alternative, personalized search technology becomes more widely appreciated and Research. In recent years, Suzhou rapid increase in cases and disputes involving intellectual property rights, the establishment of the Suzhou area library of intellectual property experts Municipal Intellectual Property Bureau depth understanding and mastery of the first-hand information on the latest of the region's industry experts. But the face of the complexity and variety of the industry in the region, different level experts in their field of study, as well as the natural language description of the key elements of the various different ways, a traditional search engine is difficult to achieve fast and accurate search requirements. In this context, the paper will be designed to LSI retrieval library system applied to Suzhou intellectual property experts. According to the survey, not yet reports of expert database application LSI retrieval. LSI technology in Suzhou intellectual property expert database retrieval system for exploratory research, and related technologies and algorithms based on the characteristics of the pool of experts and practical application of research and improvement. Including the following points: 1, existing information retrieval model to study and summarize the pros and cons; research and analysis to the premise of the existing LSI technology, the range of applications and features of the library according to the experts, the relevant technical improvement work. 2 elaborated based on the LSI the expert database search method, the use of based on the characteristics of hierarchical clustering methods to achieve fast retrieval of LSI-based experts. After a preliminary investigation, and a lot of work on the basis of realized Intellectual Property Rights Experts library prototype system, and to evaluate the precision of the system, the hit rate performance the original expert information on the database I Board.
