Design a tool for construction of unique knowledge base for expert systems

So far, many knowledge representation methods have been discussed. Each method has its own advantages and disadvantages, so it is not possible to introduce a specific method as the best knowledge representation technique. We introduce a unique knowledge base, E_x-OAV KB. As the verification and validation (V&V) of knowledge in any AI systems is important, we propose a new user friendly tool, TKT-OAV, to transform the knowledge representation method of any expert system such as semantic network or frame to the E_x-OAV KB. By using this tool, we could also draw and edit the semantic network or frame and construct the knowledge base. This tool uses the standard algorithms that have been designed by C. Dadkhah and A. Ahmad (2004) for transforming the knowledges. The transformed knowledges are shown in three forms: OAV triple, OAV hierarchy and OAV table. Finally the knowledge base which its knowledges are represented in OAV triple is created. Any expert system shell can use this KB for reasoning and the verification and validation tools like OAV_VVT expert, could also verify and validate this knowledge base.
