The Applied Research Of Information Retrieval Technology In Oilfield Information Net

As an importan means of information collection, ComputerizedInfOrmation Retrieval Technology has experienced several decades ofdevelopment. Due to the continuous progress of techLnology and fast incrementof infOrmation capacit}r, especially the development of network technology andmulti-media technolog}r. data process has transfOrmed from the traditional rnodeto a nex'!-stvle mode. For instance svstematic structure transformed fromterminal host computer rnode to client/server struct-Ure mode, networkcircumstance transformed from LAN to Internet. and infOrmation structure fromstructurization to non-stnJcturization. All these transformations x'pil] enhance thefurther research and development of Computerized Information RetrievalTechno1ogy to meet the requirement of people for improving their abilities ofcaPturing information.In the process of research, this paPer reviews the history' of computerizedinfOrmation retrieval, prospects its futUre, expatiates upon the impodrice ofinformation retrievaI at the same time, and emphasizes on studying the basictheories of the information retrieval technology a-nd the full-text database.Directed by this theory, we design and cap out a system of informationretrieval in oilfield information net, according to the need of informationdevelopment for Daqing Oilfield Limited Company. TRS and MS SQL serverare the DBMS of this system that facilitates the infOrmation search for user onneL and makes the information and resource of the department in the bureaushared, the contellt including routine information management, informationrelease on the web, and infOrmation retrieval from web. In addition, in the0A{J:7XJ:P4j.f3e@+q{ftili2course of the implementing this sys1em. x'7e apply for some basic theories ofinfOrmation retrieval technology and full-text database, techniques of Chinesefull-text database's creation concretelv.This paPer researches into the basic theories of information retrieval andfull-text database, which has theoretic significance in a way, and theimplementation of the system has considerable engineering applied significance.
