An Intelligent Web-Based Learning System for Group Collaboration Using Contracts

چکیده
In this paper we introduce an Intelligent Web-Based Learning System Virtus which supports role-based collaboration using a group contract model (a charter) based on roles and rules. The originality of our work consists, on the one hand, in proposing a declarative language to express contracts using declarative rules, commitments and role responsibilities and, on the other hand, in automatically executing the contract thanks to a knowledge-based system.
