Knowledge Representation And Query And Reasoning Research For Ergonomics Design Ontology

With the rapid development of information technology and artificial intelligence technology.It is possible to digital,information and intelligence design in the domain of ergonomics design.However,most of the knowledge sharing and communication in the field of ergonomics design is still in the use of human natural language.Human natural language is not well-structured,and can not be directly used for machine processing.There is a big gap between natural language knowledge and computer processing knowledge.In order to promote the intelligent of ergonomics design.It is necessary to study the method of knowledge representation in the field of ergonomics design,upper ontology of ergonomics design construction,ontology knowledge query and resonning mechanism.The specific research contents are as follows:Selected the ontology as a formal expression of knowledge by comparative analysising various knowledge representation methods;It is found to be helpful to improve the interoperability of ontology by using upper ontology from the basic study of ontology theory;researching domain ontology construction method,and try to choose the domain analysis as the ontology elements extraction and construction method;The reasoning logic theory and ontology reasoning technology are studied,and the Jena inference engine is selected as the mechanism of ontology reasoning.It was arrived that ergonomic design elements are mainly divided into,human factors and design process and system requirements,three dimensions from analysising the elements and relationships in the field of ergonomics design based on domain analysis,and study the relationship between these three dimensions.The conceptual framework of ergonomics design top leve ontology is according to the domain analysis results and the upper ontology.Constructing ergonomics design mata-ontology and ontology by using ontology building tools.Using web platform to build ergonomics design applications,and make ontology query and reasoning function come ture.The feasibility of ontology knowledge representation is demonstrated by using the specific application case of car driving-seat design in the workspace design.The research shows that it is feasible to apply ontology knowledge expression in the ergonomics design.It will greatly promote the intelligent process of ergonomics design.
