It is part of a PhD research project into Arabic language computing at the University of Leeds, according to the project's website.
Eric Atwell supervises the Arabic language computing research group within the School of Computing. This project is also supported by a wide community of volunteers.
The Quranic Arabic Corpus project aims to provide a richly annotated linguistic resource for researchers wanting to study the language of the Quran. The grammatical analysis will help readers further in uncovering the detailed intended meanings of each verse and sentence. Each word of the Quran is tagged with its part-of-speech as well as multiple morphological features.
Although there are other online resources that explain the Quran, few are machine-readable, or go into detailed grammatical analysis for each word in context. Having linguistic information in a format that both humans and computers can understand leads to many useful applications. By applying Arabic computing language technology to the Quran, it is possible to achieve rapid morphological and syntactic analysis that would otherwise take far longer manually.
Quranic Arabic Corpus is an annotated linguistic resource which shows the Arabic grammar, syntax and morphology for each word in the Holy Quran. The corpus provides three levels of analysis: morphological annotation, a syntactic treebank and a semantic ontology.
