Hadith Science is an entire field of study that has helped muhaddithin (hadith scholars and researchers) through ages in determining the authenticity of riwayahs (reported sayings of prophet Muhammad – may peace be upon him).
In recent years, technology has made possible amazing tools that take hadith science to a whole new level. In this video watch Hassan Ilyas demonstrate a software called جوامع الکلم that he uses on a daily basis in his research.
