Workshop on Argumentation and AI and Law

What do we Know and Where should we Go?

Part 1: Tools for AI and Law Argumentation: Part 2: Argumentation with Legal Cases

W2 of the International Conference on AI and Law Workshops

Casa Dell'Aviatore,Viale dell Universita, 20, Rome,
Monday June 10th, 2013


This workshop will comprise two sessions, intended to take the opportunity to bring together both established and young researchers to take stock of what has been achieved and to suggest possible future research directions for two important areas of AI and Law. The workshop will not be a mini conference with presentations but will be structured as a genuine working meeting designed to fulfil these purposes.

Each half-day session will be divided into two halves. The first will explore the state of the art, starting with a talk summarising some relevant achievements, followed by a commentary indicating areas of consensus, areas of controversy and other aspects not covered by the opening talk. These two talks will be followed by an open, facilitated, discussion in which the participants can express their own views on the topic.

The second half will explore how the current foundations may be built upon. This will open with a panel session in which four panellists will briefly put forward their positions. This will be followed by an open discussion in which these positions may be explored, questioned and extended. The discussion will conclude with a summary, identifying open questions.

A Handout for the workshop giving the Programme, Papers and a Selected Reading List is now available.
