Abstract
Muslims believe that the Quran is a sacred book and are words of Allah. Muslims also believe that the Quran provides a complete code of the conduct of spending their lives. That's why they find answers to their questions from the Quran. In the past, many ontology modeling and search work about Quran is performed, which have ignored simultaneous usage of Quran, Hadith, Tafsir ontology modeling and semantic search. In this paper, an ontology is developed considering Quran, Hadith and Tafsir, altogether and then semantic search is performed on Zakat, as a use case, which is one of the main pillars of Islam. Quran has allegorical complex text structure that's why usage of Tafsir and hadith to understand the Quranic concept is always emphasized. Protege editor is used for Zakat ontology development, employing top-down process consisting of three main steps, which are, data collection, precautions of data collections and development, and Zakat ontology formulation. Furthermore, Zakat ontology formulation section consists of seven steps, Informal competency questions are formulated with the help of religious scholars for performance evaluation. SPARQL query language is used for querying and results of competency questions show that proposed approach complies with competency questions.
