A new semantic expression method for web pages based on OCDB

Designing web pages by HTML documents brings many questions such as maintaining data uniformity, reusing a part of a page and searching information from the page. Semantic web is an important area and is very useful to search information from the web resources. There is much work in the area such as the resource description framework and the extensible markup language (XML). This paper presents a new semantic expression method for web pages. By introducing the concepts of the original content database (OCDB) and the extended tag graph, we give an alternative method based on graph representation to a web page. A page will be given indirectly by its virtual web page (VWP), but not by its HTML document. The VWP contains only the structure of the page without any actual content in it. The actual contents of all pages on a web are centralized in the OCDB of the web. This new technique is useful to solve the problems mentioned above. As its application we discuss the blocked design technique for web pages.
