Research on Domain Ontology Based Information Retrieval Model

This paper gives out an information retrieval system model based on Ontology. First of all, the weak point and its reason are analyzed for traditional information retrieval system,. Then, the concept of Ontology and its application in intelligent retrieval domain is introduced. Afterwards, a information retrieval system structure model, based on domain Ontology, was proposed, in which it was introduced on how to utilize domain knowledge of Ontology to realize query based on concept during the process of information retrieval. At last, it was evaluated on this model’s performance.

Constructing of marine information management platform based on ESB

Because the marine business data has the characteristics of multi-sources, heterogeneity and the types of abundance, and information systems of “Digital Sea” propose the request for marine management platform of portable and reusable. In this paper, Enterprise Service Bus (ESB) and flex technology to build a marine information management platform. The ESB adapter and message-driven services through the implementation of mechanisms for the completion of marine information and data interaction, while the use of Rich Internet applications and Java technology to realize the whole system. The system has been put into operation, practical applications indicate that the using of ESB middleware technology can increase the efficiency of system development, and flex technology enhances graphic animation.
