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 for juris-informatics 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We solicit unpublished papers on theories, technologies and applications on juris-informatics.


Relevant topics include, but are not limited to, the following:

  • Legal reasoning
  • Argumentation/Argumentation agent
  • Legal term ontology
  • Formal legal knowledge-base/Intelligent management of legal knowledge-base
  • Translation of legal documents
  • Information retrieval of legal texts
  • Computer-aided law education
  • Use of Informatics and AI in law
  • Legal issues on ubiquitous computing/multi-agent system/the Internet
  • Social implications of use of informatics and AI in law
