Argumentation graphs with constraint-based reasoning for collaborative expertise

摘要

AbstractCollaborative processes are very important in telemedicine domain since they allow for making right decisions in complex situations with multidisciplinary staff. When modelling these collaborative processes, some inconsistencies can appear. In semantic modelling (conceptual graphs), these inconsistencies are verified using constraints. In this work, collaborative processes are represented using an argumentation system modelled in a conceptual graph formalism where inconsistencies could be particular bad attack relation between arguments. To overcome these inconsistencies, two solutions are proposed. The first one is to weight the arguments evolving in the argumentation system on the basis of the competencies of the health professionals and the credibility of the sources justifying their advice (arguments), and the second one is to model some law concepts as constraints in order to check their compliance of the collaborative process.Highlights•Reasoning underlying the remote collaborative processes in complex decision making.•Abstract argumentation framework with the directed graphs to represent propositions•Conceptual graphs for ontological knowledge modelling and formal visual reasoning.•Competencies and information sources for the weighting of shared advices/opinions.•Constraints checking for conflicts detection according to medical–legal obligations.
