Thiqat System - Hadith Sciences Knowledge Graph

Project Overview

Thiqat is a comprehensive semantic-web-based knowledge graph system for Hadith sciences, modeling narrators (rawis) and important figures from the first five centuries of the Islamic calendar. The system combines graph database technology with logical reasoning capabilities to enable complex scholarly research and analysis in Hadith studies.

Core Innovation

Bridging traditional Islamic scholarship with modern semantic web technologies to create the first machine-validated, reasoning-capable platform for Hadith narrator analysis and historical research.
