Pallotta Vincenzo, Niekrasz John, Purver Matthew. Collaborative and argumentative models of natural discussions, in Proceedings of the 5th Workshop on Computational Models of Natural Argument (CMNA), Jul 2005.
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 in meetings. We highlight the complexity of the problem in modeling interaction and discourse in argumentative discussions and we propose a solution based on the construction of a specific knowledge base.
