Automatically Acquiring Requirements Model Based On Ontology And Modeling Method Research

With the constant enlargement that the information system used in enterprise's management and administration, the guarantee which the application of the information system can produce benefit for enterprise's management have become more important. An investigation since 1995 in U.S.A. which followed more than 8000 software projects show 2/3 of the projects were not finished. Analysis the failed reason among them, the reason WHICH correlates with the requirement is 45%. Therefore, expect information technical support, the information system development needs more support of earlier requirement analying and modeling.The paper using a normal requirement modeling method to solve the requirement problems in information system. The content of the paper includes:1. The basic conditions of information system requirement modeling. The part presents the definition of requirement modeling research of information system. It introduces two basic modeling methods: method based on environment case and on model.2. The present research situations of ontology. It introduces the development and definition of ontology and the application in information system requirement modeling. It discusses the relations between ontology and methods based on model.3. The core definition of ontology and its expressions. It firstly presents the relations between the core definition and definition of ontology. Then it explores the expressions of the definition.4. Requirement modeling method of information system based on ontology . This part firstly introduces a method. Then, it presents the general structure of the...
