Semantic Web: Choosing the right methodologies, tools and standards

Semantic Web is a succession of the current world wide web in which all the contents, resources and services over the web will have well-defined meanings. Due to this well-defined semantics, semantic web will enable the automated processing of web contents by machines. To achieve this vision; a number of methodologies, tools and standards for semantic web have been proposed during last few years. In this paper, a critical review of these constituents of semantic web has been presented. In particular, a comparative analysis of ontology languages, ontology tools, ontology development methodologies and semantic web services is done. In addition, some missing research areas have also been also highlighted in which further research work should be carried out.
