Over the last few years, argumentation systems have been gaining increasing importance in several areas of Artificial Intelligence, mainly as a vehicle for facilitating rationally justifiable decision making when handling incomplete and potentially inconsistent information. Argumentation provides a sound model for dialectical reasoning, which underlies discussions among students when solving tasks collaboratively in a CSCL environment. In this setting, we identify the problem of constructing Shared Knowledge and its related Shared Knowledge Awareness. While Shared Knowledge refers to the common knowledge students acquire when they work in a collaborative activity, Shared Knowledge Awareness is associated with the consciousness on the Shared Knowledge that a particular student has. This paper presents a novel approach to model Shared Knowledge construction and the associated Shared Knowledge Awareness through an automated argumentation system.
