Ontology Driven K-Portal Construction and K-Service Provision

Knowledge has been crucial for the country’s development and business intelligence, where valuable knowledge is distributed over several websites with heterogeneous formats. Moreover, finding the needed information is a complex task since there has been lack of semantic relation and organization. Even if it has been found, an overload may occur because there is no content digestion. This paper focuses on ontology-driven knowledge extraction with natural language processing techniques and a framework of usercentric design for accessing the required information based on their demands. These demands can be expressed in the form of Knowwhat, Know-why, Know-where, Know-when, Know-how, and Know-who for a question answering system
