A Visualization Tool for the Sitemap of a Knowledge Portal and the Concept Map of Group Knowledge

Contents of a website can be constructed by two means. Conventional websites usually have a sitemap initially. Using this map as a blueprint, the website designers develop the pages of the content and add links to the content of a website, such as the I-Know'05 homepage. For the website known as a knowledge portal, a sitemap cannot be prepared to outline the contents in advance. A knowledge portal site allows its members to create their own knowledge objects. The website therefore grows itself unlimitedly and unexpectedly just like a coral. Interestingly, these knowledge objects are not only represented in webpages but also associated with conceptual elements defined within the ontology of the knowledge portal. In this regard, we develop a visualization tool to display the sitemap of a knowledge portal and observe the concept map of group knowledge. As a practice platform of our visualization tool, we chose a locally developed knowledge portal, called Open Computational Problem Solving (OpenCPS) Knowledge Portal.
