Abstract�� In most of today′s enterprises, organization knowledge is located in separate operation systems, therefore the knowledge management is not well realized. Based on enterprise′s legacy systems, an application framework which supports the EKI(enterprise knowledge integration) by applying semantic web technology was proposed. The architecture of the framework was divided into four layers from bottom to top: data layer, operation application layer, knowledge integration layer and knowledge service layer. Each layer was introduced in detail. Four key techniques for the architecture, i.e. data semantic transformation, unified knowledge representation by RDF(resource description framework)/RDFS(RDF schema), constructing knowledge chain and knowledge query were further studied. An approach with eight definite steps to develop the framework was also proposed for referenced. Finally, application of the proposed framework in a famous Chinese large scale hydropower corporation was further provided to illustrate the effectiveness of the framework.
