Formalisms of Representing Knowledge

Incomplete, imprecise and large volume of data generates the concept of knowledge base. Knowledge base which is collection of facts, procedures and meaning is much better than database because it provides the power of reasoning, with the help of which the complicated questions are solved. Knowledge representation is a method to encode knowledge, beliefs, action, feeling, goals, desires, preferences and all other mental states in the Knowledge base. Semantic web defines standards for exchanging knowledge via coherent knowledge base. To develop a good knowledge base it is necessary to have good knowledge representation. For this reason, knowledge representation is our main consideration. This paper gives an overview on knowledge representation aspects in the context of semantic web.
