Abstract
In this paper, we propose a new method to analyze people’s interests by simulating the gradually changing and transferring mechanism among interests. Different boards in Bulletin Board System (BBS) which focus on various topics serve as representation of people’s interests. A technique named Dissimilarity Reconstruction (DSR) is put forward to discover relationships between the interests. DSR tries to grasp the intrinsic structure of the data set by the following steps. First, Vector Space Model (VSM) representations of the interests are obtained by taking users in BBS as terms and the numbers of messages they post as weights. Second, dissimilarities are calculated from the interest vectors. Finally, the nonlinear technique Isomap is engaged to map the interests into the intrinsic dimensional space of the data set where Euclidean distance between two interests well represents their relationship.
