Development of Ontology in Laptop Domain for Knowledge Representation

Large amount of information is available on the World Wide Web(WWW), which when searched through major search engines provides a lot of unwanted information, requiring relevant information to be extracted, consuming a lot of effort and time. Ontologies prove to be a technique for effective knowledge representation and information retrieval, which is the core concept in semantic web applications. Knowledge representation with ontologies helps in effective information retrieval as compared to other technologies of representation.This paper discusses about the requirement for ontology development, different tools for ontology development and the query languages to handle the knowledge. Three ontologies are created in the domain of laptop to deal with the problem of effective information retrieval and its coverage domain is validated with a set of queries executed with DL (Description logic) language on the developed ontologies.
