QuranAnalysis (QA) Project


The goal of this project is to build a Semantic Search and Intelligence System for the Quran, providing normal users and scholars the ability to search the Quran semantically, analyse all aspects of the text, find hidden patterns and associations using state-of-the-art visualization techniques.

QA started as an MSc project at the University of Leeds in 2015 supervised by Eric Atwell. The project aimed to glu-together and build on previous research done in the university providing an opensource framework for Quran Analysis work, a framework which can facilitate research, boost applications and foster innovation in that area.

More information can be found in my Thesis below

QuranAnalysis: A Semantic Search and Intelligence System for the Quran

Feel free to use QA in your research or applications, also contributions are welcome.

How can you benefit from QA ?

Assuming you are a developer or researcher, with more than 20,000 lines of code you can benefit in many ways as explained below

  • Access to language corpus and resources (inlcuding QA Ontology)
  • Reusable code and algorithms
  • Libraries for various tasks around Arabic Language handling, Data Model manipulation, NLP, Semantics, and Quran specifics
  • QA Ontology extraction module
  • Search Engine, Question Answering and Semantic Application Implementation
  • Novel D3 visualzation techniques
  • Speed up prototyping by reusing QA user interface

QA Unique Resources

  1. QA Ontology: OWL file including rich concepts, relations and metadata from the Quran
  2. Stopwords Lists: Quranic stop words lists
  3. Simple to Uthmani Mapping File: A file containing one-to-one mapping between simple and uthmani words from the Quran
  4. Qurana to QAC segment Mapping File: QAC and Qurana has different segments counts. The file includes one-to-one mapping between QAC and Qurana segment numbers
  5. Longest Common Substrings in the Quran: A file containing all common substrings in the Quran - extracted using LCS algorithm

Project Structure



I am sorry that some parts in the code are messy, undocumented and not well designed, this is due to shortage of time, stress and the novelty aspect of the project which lead me to focus more on research, coding and thesis writing to meet deadlines. I thought releasing the code this way is much better than waiting until i have time to clean it up which can take forever.
