A Research On Information Search Engine Technology Basased On Network Information Organization Theory

library and information circles, computer and information industry circles, whose scholars have began effective research on it Though mere has been a great deal of research on network information organization and search engine technology, mere is still short of systematical discussion of the theoretical basis of network information organizatioa Especially few have take notice of the idea that to what extent can search engine technology support to organize network information. As to all these concerns, this thesis discussed some problems involved in me relationship of network information organization and search engine technology.T Internet is world-wide, which makes it distributes all over the world, and also makes it difficult to be organized and managed uniformly. On the other hand, the great development of Internet makes cyberspace the most important information resource. Network information resource has the characteristics of great number, the variety of forms, the wide range of content, and with little professionalism. All these produced new problems and challenges on the work of information organization. With the great efforts and dedication of most of the Sci-tech information workers, the network information organization technology has made great progress. Internet search engine is one of the most important developments of the network information resources management and retrieval technology. The development and utilization of network information search engine have made remarkable progress, and became a new industry. The theory and technology of network information organization have aroused more and more interests of information workers who began to perform research on them. At April of 1994, the search engine webcrawler was issued formally on the Internet and began its service. This has great effects on the development of network. Now search engine have became the number two Internet application technology, just after E-mail. Search engine draw great interests from many people, including his thesis consists of two parts. In the first part, me research is focused on some theoretical basis of network information organization, including its concepts, basic theory, ways and means, technology research, practice and actuality analysis, development, language tools and so on. Accordingly, explain the significance and necessity of information organizatioa The second part is mainly about research of search engine, as an important information organization tool in the network environment Firstly, the concepts, characteristics, types and principles of search engine were analyzed. Then on the basis of broad investigation on Internet search engine, the author listed the use and characteristics of me eight most popular search engines, and compared their search effects. Consequently, some discussion on search engine has been made, including the search effects and existing questions, developing situations and development In addition, put forward some new development direction of search engine technology, such as intelligent search, personalizing search, structured search, vertical professional search and localizing search.
