Design of an Ontology Language and the Ontology Building Tools

In recently years,ontology has become one of the most important disciplines in the fields of Requirement Engineering.Many experts focus their mind on the subjects of ontology language and ontology building.However,now,there are two problems in this field,First of all,it is difficult for common users to use the ontology languages,most of which are based on complex syntax and logic.The second,usually,the ontology building tools,which lack of function to support reuse and program on the ontology base,can only support ontology representation and terms browsing.This paper reports on a new ontology language,named PNL-ODL(Pseudo Natural Language Ontology Description Language) and an ontology building tools based on PNL-ODL,designed and developed in our lab.PNL-ODL can easily be used by people lack of knowledge on computer science and on support of the ontology building tools user can build the ontology base conveniently.Furthermore,we also introduce the organization ontology,which is represented in PNL-ODL,to discuss the reusable ability of ontology.
