Construction Of A Uniform Literature Resources Search Platform Base On TRS Information Retrieve Technology

The diversity and heterogeneity of digital literature caused inconvenience to readers in information retrieval. This paper is focus on the special problem in centralized digital literature retrieval and explores avenue to promote retrieval efficiency. Main theories of information retrieval technology have been studied, including theories about segmentation of the search, relevance ranking and retrieval and apply these theories to centralized digital literature retrieval in digital library system.Based on the centralized retrieval theory and the actual situation of the library under Central South University, the author tries to design a different type of metadata structure of literature resource and to establish a digital literature resource standard. Integrated and merged variety of metadata to build a digital library metadata storage system. The centralized digital literature retrieval platform is implemented by using metadata storage and full-text search technologies. Retrieval efficiency is greatly improved by the full use of those technologies such as keywords real time prompt, keywords filtrate, relevant retrieval, and classified statistics, etc.In general, practice shows that the research of centralized digital literature retrieval platform is of practical use in the use of digital library resources. It also provides technical support to subsequent customized service.
