Arabic and Quran

JQuranTree - Overview

JQuranTree is organized into three parts: The Quranic text itself, a set of access APIs, and a set of analysis APIs. The distinction between accessing and analyzing the Quran is that access is concerned with representing the Arabic text (e.g. chapters, verses, letters and diacritics), whereas the analysis API is built on top of this, providing more sophisticated tools for computational linguistics
