Information Integration Based on Description Logics under P2P Environment
Wang Ju · Microelectronics & Computer · 2007
The relationship of description logics and information integration,especially the current research progresses and the existing problems of description logic for information integration,are analyzed. Based on the work of D Calvanese,the method of description logic DLR based information integration under P2P environment is further studied. The formal definition of description logic DLR based P2P information integration system is given. How to translate P2P information integration system into a uniform description logic GDL is studied,and the correctness of the translation method is proved. And the method of query and its implement of description logic DLR based information integration under P2P environment are given.
