Abstract : Semantic Web is an approach to facilitate communication by making the web suitable for computers. To enhance current Web, a semantic layer should be added to the web pages to enable computers understand them. Recently, some annotation tools have been developed to make machine understandable data on the web. However, little number of tools are concerned with the Arabic Language, although, this language is the mother tongue of more than 293 million of people in 23 countries. This paper first presents an overview of the existing Semantic Web concerning the Arabic Language in the domain of Ontology building. Then, some examples of the tools that can be used in the semantic annotation process are discussed. Finally, a framework is proposed to develop a semantic annotation tool for supporting Arabic contents. Keywords: Semantic Web; Annotation Tools; Software Architecture; Arabic Language; Ontology.
