In order to give users integrated access to a large number of heterogeneous, autonomous information sources, we need an effective and efficient mechanism for enabling knowledge to be shared and exchanged. Sharing of knowledge, to be efficient and effective, must take account of semantic representation and semantic integration. In this paper, we provide a mechanism for knowledge sharing. We have made use of Word Net as linguistic knowledge to represent and interpret the meaning of the information, to integrate the information, and to give users efficient access to the integrated information.
