Reasoning in Semantic Web Using Jena

Semantic web extends the current web by adding semantics. By adding semantics we enable intelligent reasoning to be done on web. In this paper an application is created in eclipse using Jena semantic web development framework. Application developed consists of creating several classes and properties. Jena supports three operations on the model which were shown by creating two appropriate schemas. Reasoning capabilities of Jena is demonstrated by applying an OWL reasoner to the application for additional inference. At last the validity of the inference made after reasoning was tested and it was found to be consistent. Keywords: Semantic web, Ontology, Eclipse, Jena, Reasoner

Semantic Web Personalization: A Survey

With millions of pages available on web, it has become difficult to access relevant information. One possible approach to solve this problem is web personalization. Web personalization is defined as any action that customizes the information or services provided by a web site to an individual. When personalization is applied to the semantic web it offers many advantages when compared to the traditional web because semantic web integrates semantics with the unstructured data on web so that intelligent techniques can be applied to get more efficient results. We have presented various approaches that are used for personalization in semantic web in this paper. The core of semantic web is the ontologies which are defined as explicit formalization of a shared understanding of a conceptualization. We exploit the machine understandable feature of semantic web to device strategies that perform effective personalization such that the results returned to the user are more relevant to the goal set by him. In this paper we have presented the classification of personalization techniques used for semantic web. Keywords: semantic web,ontologies,personalization,recommendation,user profile
