In conventional collaborative learning, a small group of students share intellectual effort to pursue a consensual resolution. Traditional communication by means of, for instance verbal or written discourse is a typical tool that helps group members exchange ideas and concepts. However, this tool is not sufficiently effective to foster student attempts to form a consensus. Moreover, referential information is needed as evidence to support their understanding and interpretation of certain concepts during group discussions. To address these problems, I propose a new approach to comparing and merging mind maps produced individually by students in a group. The proposed system integrates Linked Open Data (LOD) standard web technologies to facilitate consensus-building processes. It also employs the Resource Description Framework (RDF) to uniformly represent mind maps, which enables computability and sharing of mind maps. For example, merging a set of given mind maps, a mechanism required in the formation of a group mind map, can be carried out by combining RDF graphs, each of which corresponding to one of the given mind map. A prototype is developed and evaluated in a group of 24 students using 3 criteria; system usability, student satisfaction and learning outcome. The results show that the proposed system outperforms the traditional method significantly, as it improves students performance in discovering new knowledge, creativity, group collaboration, and consensus reaching.
