Research And Implementation Of Intelligent Information Retrieval Technology In American Health Care System

With the development of information industrialization, more and more enterprises have built their own information systems. How to provide an efficient, flexible and accurate information retrieval system for enterprises becomes a hot topic of information retrieval.In this paper, the key technologies of intelligent information retrieval have been studied first. After the analysis and construction of Health Care Information System, the module of intelligent information retrieval has been developed for this system.This paper mainly includes:(1) Have analyzed the design of intelligent information retrieval and researched the frame of intelligent information retrieval.(2) Have deeply researched the key technologies of intelligent information retrival such as the conventional information retrieval model, the information retrieval model based on concept, natural language understanding and personalized retrieval.(3) Have designed the Health Care System. Modeling the operation flow and requirement of the system, and have built the static diagram and dynamic behavior diagram as well as the structural diagram.The system has been run in business.(4) Have designed the module of intelligent information retrieval by researching on those technologies, which has been realized in Health Care Information System. The module of intelligent information retrieval has provided the users with an intelligent and personalized information retrieval service in Health Care Information System. In the respect of personalized retrieval, not only the user model has been set up, but also the consummation of user model has been realized in combination with user interests learning and user interests judging algorithm. At users interface, users can evaluate and feedback the results of retrieving, which have further enhanced the interaction between users and system.Meanwhile, the tedious grammars and rules of searching have been avoided by using simple natural language search. The module of intelligent information retrieval is an innovation of the system, which makes the commercial system favored by customers.
