In this paper, we present a revision approach for creativity evaluation of collaborative design. In the original clustering method, the creativity level of Linkography is calculated by two parameters: Average distances and Coefficient of variance among clusters. The method could cause problem when two Linkographys are of different size but happen to have identical parameters. To deal with such problem, we propose to adopt a global factor for the whole Linkography and a local factor for entropy calculation of every cluster. The effectiveness of the proposed revision is verified by two empirical studies. Firstly, a total of six Linkographys composing a pair of 20, 30 and 40 moves are generated by our computer program designated for this study. By applying the two proposed modification factors, the reduction of creativity level for those over-sparse or over-dense Linkographys are achieved. The second study takes the outputs of collaborative designs executed by novice team and expert team. Two Linkographys are produced and the analyses steps are the same as study 1. The creativity level of expert team becomes larger than novice after the appliance of proposed modification factors. The outcome shows the necessity of revising Linkography clustering method.
