Research On Information Representation And Semanticalizing Procedure Based On Semantic Web

The Web was designed as an information space,with the goal that it should be useful not only for human-human communication,but also that machine would be able to participate and help. One of the major obstacles to this has been the fact that most information on the Web is designed for human consumption,and even if it was derived from a database with well defined meanings for its columns,that the semantics of the data is not understandable to every computer on the web.The Semantic Web is a vision:the idea of having data on the Web defined and linked in a way that it can be used by machines not just for display purposes,but for automation,integration and reuse of data across various applications. The Semantic Web is the abstract representation of data on the World Wide Web,based on the RDF standards and other standards to be defined. "The Semantic Web is an extension of the current web in which information is given well-defined meaning,better enabling computers and people to work in cooperation." (Tim Berners-Lee)Facilities and technologies to put machine-understandable data on the Web are rapidly becoming a high priority for many communities. This dissertation introduces the knowledge ofSemantic Web and ontology,and presents the new Semantic Web language------OWL. Then wediscuss the related research topics as follows:It's not easy for traditional standard such as STEP to describe product information in a semantic way,and also STEP is not a Web-based standard. The development of Semantic Web is making itself be an important method to facilitate the knowledge-based information integration. So we propose to use OWL to describe product information,and give the instances as example.Information integration in the entire life science has become a challenge to bioinformatics and computer science. We first give a survey of ontology-based systems for bioinformatics that are in different languages and different semantic representation ways,and then present the idea of using OWL to describe the information of molecular biology for bioinformatics and give the instances for example in the end.XML is increasingly becoming the standard language for information exchanging on the Web,but it has no sufficient mechanism to represent information in a semantic way. Therefore,it is required to study the method of transforming XML data into Semantic Web-based representation to facilitate information integration at semantic level. We present a framework called 'Semanticalizing Procedure' to transform XML data sourceinto OWL-the new Semantic Web languages proposed by W3C,and give theinstances and the conclusion in the end.
