Research On Description Language Of Dynamic Ontology Based On Mutual-description Principle

As the blueprint of the Internet, the semantic web is a network that can judge something according to the semantics. It can not only understand human language, but also can identify the semantics of the information. Besides, it can interpret and process it aotomatically. The forth floor of the semantic web architecture is ontology layer. As the key of semantic web technology, it is the foundation of solving the problem of sharing and exchanging information. So it is necessary to make a research on ontology description language. Ontology aims to describe specific research in form of a formalized and shared conceptual model. In fact, ontology delineates the basic knowledge system and descriptive language of a certain field through description of concepts, terminology and its relationships.The current theory of ontology describes resource and its relationships invariably. Neverthless, the semantics of information vary in different areas, different cultures and different social environments. Besides, the semantics will also be changed with the changing of external factors. So the theory of ontology needs extension. Combined with the theory of Mutual-description Principle, Fuzziness Principle, Evolution Principle,Agent, dynamic ontology and its architecture and current theory and so on., we provided the basic vocabulary, grammatical structures and semantic description of a Dynamic Ontology Description Language, using DODL language to describe the state of two Agents combined to move blocks.This paper is specific for the following research:(1) A deep discussion of the definition of ontology and the description language are made.(2) A deep research of Agent, including the definition, the relationship of Agent and Object, the BDI model, especially its pragmatic syllogism are made.(3) Researched on Mutual-description Principle, Fuzziness Principle and EvolutionPrinciple,and also researched dynamic ontology’s AOR formal model, architecture and related theories.(4) Through definiting the major components of a Dynamic Ontology, such as Agent, Object, Class,ontology and so on, we provided the basic vocabulary, grammatical structures and semantic description of this Dynamic Ontology Description Language,and using BNF to descript DODL’s Syntax for the normalized description.(5) Descripted the staes of two Agents combined to move blocks with DODL, and also designed and realized the program.
