Abstract: Semantic Web is the representation of knowledge which consists of a huge amount of ontologies. Ontologies provide an efficient way to reduce the amount of information overload by defining the structure of a specific domain and enabling easier access to the information. Ontology search can prove its excellence only when the retrieval involves highly relevant information based on the userís query. The ranking method increases the scope of knowledge searching in ontology-driven searches. This paper reviews most of the ontology ranking methods used, which will help researchers to proceed further.

Keywords: Semantic web, Semantic search, ontology, ontology ranking.
