Research And Practice On A Mechanism Of Integrated Information Service Based On Ontology

Information and knowledge are the most important resources for the development of an enterprise. The main function of information service is to guarantee the efficient obtaining and using of information. A good information service can improve the speed and quality of information retrieval; therefore improve the user's work efficiency. For enterprise, a systematic and efficient information management is a significant method to improve enterprise operating efficiency, ensure the good business decisions making and increase the competition of the enterprise.Based on the research of Ontology, Metadata technologies and many other information service techniques, a new mechanism of integrated information service based on ontology is put forward by this paper, according to the characters and requirements of modern enterprise information integration and service circumstances. In this mechanism, the integration of distributed Heterogeneous data sources is well implemented by establishing domain ontology model and semantic metadata platform, with which the problem of enterprise information redundancy, data inconsistentness and semantic ambiguity is effectively solved. Various requirements of enterprise information service are discussed in this mechanism; and several service modes are designed to satisfy the users' need. Especially the active information service is expected to push the right information at the right time to the right person by the right method.Based on the ontology and metadata models, the mechanism of integrated information service introduced in this paper provides semantic oriented integrated information service. By using this mechanism, the users' requirements can be captured more friendly, more efficiently and also more intelligent. Moreover, it can offer intellectualized and active information service. The Web Service information service technology is used in this mechanism, which makes the information service system more flexible and general and improves the expansibility and reusability of the system. A new information service mode combining ad hoc queries with active push is designed in this project, which can provide completely intelligent information service. The system user interface is based on Ontology concept, which can be understood by both human and computers. By this method, the computer system can well understand users' needs, and therefore capture the user information more efficiently and correctly. On the whole, the mechanism put forward by this paper, which provides a real-time and active information push service, solves the problem of the overflow of the information, saves the time of the users and supports the enterprise during the real time decision-making.At last, a practice of the ontology based integrated information service mechanism has been carried out in customer information integration of telecom industry. The telecom customer integrated information service prototype system is designed and implemented.
