Non-monotonic Reasoning on the Web

Abstract

In this tutorial we describe the approaches to non monotonic reasoning as a means for inference on the web. In particular we are focusing on the ways in which reasoning technologies have adapted to five different issues of the modern era world wide web: (a) epistemic aspects, bound by the new models of the social web, (b) changes over time, (c) language variants, including different languages of deployment of a web site, (d) agent-based knowledge deployment, due to social networks and blogs, (e) dialogue aspects, introduced again in blogs and social networks. The presentation covers these aspects by a technical viewpoint, including the introduction of specific knowledge-driven methods. The technical issues will be provided within a general logical framework known as defeasible logic.
