A Multi-level Approach for Document Clustering
نویسندگان
چکیده
The divisive MinMaxCut algorithm of Ding et al. [3] produces more accurate clustering results than existing document cluster methods. Multilevel algorithms [4, 1, 5, 7] have been used to boost the speed of graph partitioning algorithms. We combine these two algorithms to construct faster and more accurate algorithm. In this new algorithm, the original graph is coarsened, partitioned by the divisive MinMaxCut algorithm and then decoarsened. A refining algorithm is also applied to improve the accuracy at each level.

Data clustering is one of the most important areas of research in data mining and knowledge discovery. Recent research in this area has shown that the best clustering results can be achieved using multi-objective methods. In other words, assuming more than one criterion as objective functions for clustering data can measurably increase the quality of clustering. In this study, a model with two ...
