Ontology Based Web Portal Designing

Web is a growing source of information. Web users surf web for different purpose. Some users surf the web to work, some for fun, students surf it for study purpose and particular users for financial information. These users visit dozen to twenty websites where they can find interesting information. Web portal is a special kind of dataintensive website that collects information from different source and organizes in a hierarchical way. Web portal is easy to design and populate according to end user purpose, but it leaves back-end database lacking of subject domain semantics and user cannot retrieve relevant information. Ontology based web portal is the solution of this problem which adds a semantic ‘layer’ in web portal implementation. This paper gives an approach that uses power of semantics to create a new type of web portal that is fully ontology based. Idea is to allow a user to create a new website by extracting information from different website’s sections selected by himself.
