Aims and Scope

Juris-informatics is a new research area which studies legal issues from the perspective of informatics. The purpose of this workshop is to discuss both the fundamental and practical issues among people from the various backgrounds such as law, social science, information and intelligent technology, logic and philosophy, including the conventional "AI and law" area. We solicit unpublished papers on theories, technologies and applications on juris-informatics.

Bar Exam Competition (COLIEE2022)

This year, JURISIN will co-located with the Seventh Competition on Legal Information Extraction/Entailment (COLIEE-2022). The motivation for the competition is to help create a research community of practice for the capture and use of legal information. Please visit the homepage of COLIEE2022 ( to see the detail of the competition.
