Semantic Aproximation Information Retrieval Research On Distributed Environment

With the continual increase of data and information on Web,the traditional means of keyword based information query cannot meet the needs of users.We proposed a novel approach for semantic approximation of information query based on semantic Web environments and synchronization renewal approach based on distributed environment. We also exploited the implementation technologies related to the approach.Furthermore, using the proposed approach,a distributed semantic query system(DSQ) was developed for successfully performing tasks of semantic queries across multiple ontologies based on a multi-agent system.The experimental results show that our approach is efficient.In order to achieve the distributed environment of multi-ontology synchronous real-time updates,first of all put forward the ontology update strategy,followed by real-time ontology strategy to solve a number of difficulties in real-time updates ontology,and proceed to realize the distributed real-time update system,which can be multi-agent environment bound by a number of real-time updates ontology.
