Semantics of Opinion Transitions in Multi-Agent Forum Argumentation

A paper submitted to the 16th Pacific Rim International Conference on Artificial Intelligence (PRICAI2019) was awarded the "Best Paper Award" from among 265 papers submitted to the conference.

Abstract：There are online forums such as changemyview where a user may submit his/her views on a subject matter, against which other users argue to try to change the opinions of his/hers. To measure the quality of such discussion, one useful criterion is how influential a given topic is to participating users' opinion changes, as may be measured by the change (if any) in the proportion of supporting-objecting-mixed opinions by users. In this work, we incorporated the notion of agency into a previously proposed argumentation framework for issue-based information systems, QuAD, and formulated semantics of opinion transitions by newly considering agent-wise evaluation of QuAD initial scores.
