A hypertext database for advanced sharing of distributed web pages

Abstract

There are many learning systems using their web pages. These systems provide not only contents of the web pages but also the embedded links on them for learners. In these systems, since the learners can use all the hyperlinks embedded on the web page, they can visit unnecessary/invalid web pages for learning. In order to use web pages as instructional materials, authors of instructional materials need to be able to select appropriate web pages. Moreover, it is necessary to provide only the hyperlinks among these selected pages. We propose a "hyperlink view". This notion means the network of these selected web pages and hyperlinks. We regard this style of reusing web pages based on the hyperlink view as the advanced sharing of them. We manage the information of many hyperlink views in the hypertext database.
