Research And Design Of Semantic Blog

With the development of Web2.0, the technology and concept of Blog expand fast, which has become one of the most important flat roof of personal information management gradually. At the same time, The Semantic Web technology, as a hotspot of academic research, has gotten a great number of achievements, and given birth to a number of recommendatory drafts. It means that the Semantic Web is likely to become more and more important in the Web development. Blog is a widely-used tool and needs the support of semantic. So we can start with Blog, studying the integration with Semantic, setting out the superiority of semantic technology and promoting the development of SW.This article investigated and studied the Blog's concept, the classification, the essential technology and the application, and then proposed the improvement suggestion and methods to improve the Blog. That is, the application of semantic web technology in Blog. Then studied the semantic web and the related system which involves in semantic Blog development, mainly includes: RDF, Ontology, RSS1.0, FOAF, WordNet, Sesame. On the basis of study above, this article tried to explore the best point of integration of the two, attempts to increase the semantic function in Blog, enables it to satisfy the demand of knowledge organization, retrieval, sharing and so on. Semantic Blog's main function and principle as follows:(1)Good community function. The system uses the FOAF ontology to manage the users, to make community user management more standard and more convenient. (2)Individual bookmark management function. Making the individual bookmark expediently, and easily for the management of article classification, also the bookmark sharing became easier.(3)Semantic retrieval function. To use the RDF to store the data, enables the data to include the semantics, uses WordNet to expand the retrieval words, and further retrieves through the friends who have the same interests, this will achieves the goal of semantic retrieval.(4)Good information subscription and browsing function. Uses the RDF based RSS1.0 to publish the information, which can be better to discover and integrate.After analyzing the system demand carefully, we carried on the usecase design, and analyzed the browsing article usecase and searching article usecase with emphasis, which established the system main function. In the full consideration of system flexibility and expansibility, this system uses J2EE based three levels constructions (expression level, logical level and data level), specially aimed at the data level to develop the community ontology, the Blog main page ontology, the Blog article ontology, to further improve the system standardization and expansibility. Under such system structure, this system mainly designed the module below to realize the system function: RDF data management module, index module, user administration module, article administration module, user label administration module and information retrieval module.
