A Role of Semantic Web and Ontology in Information Retrieval

Web Mining is an application of data mining which focuses on discovering relevant data from Web content. The Semantic Web describes a web as data rather than documents. It characterizes information in understandable manner moreimplicitly for humans and computers.It wasdeveloped with the help of Ontology, which is the pillar of the Semantic Web. The semantic Web depends on integration and use of semantic data, and sematic data is depends on ontology. Ontology can provide a common vocabulary, a grammar for publishing data, and can supply a semantic d data which can be used to preserve the Ontologies and keep them ready for inference. This also helps in personalized filtering mechanisms for users to consume relevant, interesting information from web sites. By combining web mining and sematic web, we can retrieve relevant data called as semantic web mining. This paper gives an overview of sematic web mining and their applications
