A Domain Knowledge Based Model For Personalized Browsing Sapce Of Networked Information

With the development of Network, Web has being a huge distributed networked information space. It provides a lot of worthy information resource for the reader. However, the reader often lose his way in the Web ocean when he searching information. This is because that useable methods, search and browse, for the reader to get information on the Web have some shortage. Search engine gives the search result for the reader is URL (Uniform Resource Locator) list, and most of URLs of this URL list are not the information that the reader wants. And, the reader wants to judge and hit the URL that is correlative with his search request, and browse the Web page. These Web pages will connect other Web pages by hyperlink. These all Web pages build a traditional space by hyperlink. Traditional spaces are the writer's expressive space which hyperlink built by Web page designer's logical thinking. All these traditional spaces's structures which built by hyperlinks are isomeric with and independent of each other. Because each writer's logical thinking is different with other. Therefore, the reader has trouble to finding his required information in such strange anddifferent writer's expressive space. At the same time, the reader is easy to lose his way in hyperlinks that is such not accord with his logical thinking.Aim at the problem that the traditional space and the search engine could not satisfy the reader's personalized browsing requirement, this paper provide the networked information personalized browsing space based on domain knowledge. It is a sub-item of the item that is Nation Natural Science Foundation of China. This paper plans to build a networked information personalized browsing space based on domain knowledge, which based on the reader's required information and structured by the reader's logical thinking. This browsing space let the reader exactly and quickly gets the personalized information. And, the reader will feel that he is browsing information by his memory when he browsing in this browsing space. The reader could not lose his way in this browsing space and satisfy his personalized requirement.The innovations about the networked information personalized browsing space based on domain knowledge are: (1) The browsing space is a personalized browsing space for each reader. (2) The browsing space displays the information that the reader wants. (3) The displayed structure of Web page will be changed according to the reader's requirement. (4) The browsing space automatically creates according to the reader's logical thinking. And, the Web pages hyperlinks' building is satisfy the reader's personalized browsing requirement.By studying domain knowledge, this paper analyzes the domain knowledge base ontology model and builds the domain knowledge system structure ontology model and the domainknowledge ontology description model. The domain knowledge base provides semantic description for the reader's required information model and personalized browsing space model.This paper definitely describes the reader's required information and builds the reader's required information model. And then, this paper creates for the personalized browsing space ontology model based on the reader's required information model. This paper adopt the ontology language OWL (Web Ontology Language) to describe the domain knowledge base ontology model, the reader required information ontology model and the personalized browsing space ontology model.The information resource about the networked information personalized browsing space based on domain knowledge comes from Web. And the information resource, which displayed in the browsing space, settled by the reader required information ontology model.
