Concept Markup And Concept System Used To Construct Semantic Web

The Semantic Web is an extension of the current Web and adds the linguistic meaning to the Web. The linguistic meaning is composed of the distinct meaning and the connotational meaning, the former is the idea in human brain, but the latter is related to the context wherein language using. As the simulation of the context in the computer field is restricted by the technology, the connotational meaning has to be ignored and the concept nearly is considered as the idea, so that the definition that the linguistic meaning equal to the concept is deduced. The Web is a set of the information marked up by the format tag, whereas the Semantic Web is one by the concept tag, and the two measures of the extension are employed to implement the concept markup of the information and to build the concept systems within computers. The concept markup is to mark up the information inputted into computer for processing with the concept tag, and its difficulties at present are how to partition the information, how to select the concept tag, and how to realize the automation of markup process. The concept system is just the ontology, its functions are to understand the distinct meaning of information and to carry out the concept inference, besides the latter is just the remarkable character. Nowadays, the majority of researches on the concept system focus on the problems of the huge scale, the durative maintenance, the distributed architecture and its integration applications.
