A Study On Subject Organization Techniques Of Internet Information Resources And Its Performance Optimizing

The new network information environment has not only offered the new channel for access and obtaining of information, also changes the thoughts and way that people's information organization and retrieval to a great extent. In the network information environment, people are faced with the conflict between rapid increase of online digitized information and the users' specific demands for information, so the task of the information organization is unusually arduous. The application of the thought and principle of knowledge organization and information retrieval language in the network environment can make the efficiency of network information organization and retrieval improved greatly. Because the subject language has always been one of the important components of information retrieval language, its prospect is to be very wide, especially in the network information organization and retrieval, and this can not go without its inherent performance advantage. However, while the concept, type and mode of using of subject organization technique changed, its performance has been changing with it too. The inherent advantage and positive adjustment on performance are true reasons of subject organization technique's constantly progress, and it has also determined the unsubstitutability of the subject organization technique. Meanwhile, deficiency and defect of performance is the breakthrough point of subject organization technique too. Find out these breakthrough points of its performance, far-reaching for future development of the subject organization technique.This paper is started with current application, situation of the subject organization technique in the new network information environment, and has discussed the impact of network environment on performance of subject organization technique and the development of subject organization technique's performance relatively systematically and deeply. Based on a series of performance evaluation experiment, it has also summarized advantage and deficiency existing on the performance of subject organization technique. Combined with the practice of investigation, the paper has put forward some optimize measures, principles and questions that should be noticed under the present network information environment.The paper is divided into 5 parts altogether:1.Summary of information organization of the networkThe quantity of information resources in the network increases sharply, and the importance of the information organization is more and more outstanding. But network information organization has gone beyond the scope of management style of nontraditional network information resources already, so traditional documentation organization theories and methods are faced with challenges. The application of subject organization technique in the network information organization is one of the achievements of the transplant of knowledge organization and information retrieval language thoughts and principles to network environment.2-Current situation of the development of subject organization technique in the network information organizationIn the network information organization, as to the development of subject organization technique's theory and practice, the opportunities and challenges coexist. The current situation of the development of subject organization technique in the network information organization displays in two following respects mainly: First of all, traditional subject headings, thesaurus andkeywords yet work in the network information organization, and their performance is greatly improved too; Secondly, there are some new break-throughs under the network environment in the subject organization technique, for example: extensively use of integrative retrieval language principle, constant development and type diversification of word lists etc.3. Study of subject organization technique in the network environmentIn this part, it has also analyzed the influences and changes that subject organization technique performance has received in the network environment...
