Resumen Argumentative debates are a powerful tool for resolving conflicts and reaching agreements in open environments such as on-line communities. Here we introduce an argumentation framework to structure argumentative debates. Our framework represents the arguments issued by the participants involved in a debate, the (attack and defence) relationships between them, as well as participants? op...

While recent years have seen a surge of interest in automated essay grading, including work on grading essays with respect to particular dimensions such as prompt adherence, coherence, and technical quality, there has been relatively little work on grading the essay dimension of argument strength, which is arguably the most important aspect of argumentative essays. We introduce a new corpus of ...

Defeasible argumentation is a form of defeasible reasoning, that emphasizes the notion of an argument. An argument A for a conclusion q is a tentative piece of reasoning which supports q. In an argumentative framework, common sense reasoning can be modeled as a process in which we must determine whether an argument justifies its conclusion. The process mentioned above takes considerable computa...

This paper describes the development of a written corpus of argumentative reasoning. Arguments in the corpus have been analysed using state of the art techniques from argumentation theory and have been marked up using an open, reusable markup language. A number of the key challenges enountered during the process are explored, and preliminary observations about features such as intercoder reliab...

Knowledge about he discourse-level structure of a scientific article isuseful for flexible and sub-domain independent automatic abstraction. We are interested in the automatic identification of content units ("argumentative entities") in the source text, such as GOAL OR PROBLEM STATEMENT, CONCLUSIONS and RESULTS. In this paper, we present an extension fKupiec et al.’s methodology fortrainable s...

We report in this paper experiences and insights resulting from the first two years of work in two similar projects on meeting tracking and understanding. The projects are the DARPA-funded CALO project and the Swiss National research project IM2. The findings from these two projects have been shared and compared in order to come up with a joint ontology as a model for argumentative discussions ...
