Abstract:

In order to overcome the shortcoming of the classical description logic in the expression of uncertain knowledge, this paper proposes a new cloud-based description logic C-SHOIQ （Cloud-SHOIQ） by combining the description logic SHOIQ with the fuzzy logic. In the investigation, first, the syntax and semantics of C-SHOIQ are presented, and the capability of processing the randomness and fuzziness of knowledge is analyzed by some exampies. Next, the reasoning approach of C-SHOIQ and the improved rules mapping the C-SHOIQ KB （Knowledge Base） to the classical SHOIQ KB are described. Then, the consistency of the satisfiability between C-SHOIQ concepts and corresponding classical SHOIQ concepts is demonstrated. Finally, the extension of expression ability of fuzzy SHOIQ to C-SHOIQ is demonstrated.
