Public, parliamentary and television debates are commonplace in modern democracies. However, developing an understanding and communicating with others is often limited to passive viewing or, at best, textual discussion on social media. To address this, we present the design and implementation of Deb8, a tool that allows collaborative analysis of video-based TV debates. The tool provides a novel UI designed to enable and capture rich synchronous collaborative discussion of videos based on argumentation graphs that link quotes of the video, opinions, questions, and external evidence. Deb8 supports the creation of rich idea structures based on argumentation theory as well as collaborative tagging of the relevance, support and trustworthiness of the different elements. We evaluated the design of the tool in a study of three groups of three people. We present the results of the study and a reflection on the challenges involved.

Concepts are fundamental to the rational communication through language. In the philosophical process, concepts are used either as instruments or as objects of inquiry, and play a very important role in the expression and organization of knowledge. On the other hand, the notion of concept was formally treated in a mathematical theory called Formal Concept Analysis (FCA), which deals basically with data analysis and knowledge processing. Our research aimed the study of the similarities between the philosophical and the mathematical approaches involved in the notion of concept.
