Abstract
Recent advances in Text Mining and Natural Language Processing have enabled the development of semantic analysis for religious text, available online for free. The availability of information is a key factor in knowledge acquisition. Sharing information is an important reason for developing an ontology. This paper reports on a survey of recent Qur'an ontology research projects, comparing them in 9 criteria. We conclude that most of the ontologies built for the Qur'an are incomplete and/or focused in a limited specific domain. There is no clear consensus on the semantic annotation format, technology to be used, or how to verify or validate the results.
