An Improved Of Chinese Text Hierarchical Clustering Algorithm

hierarchical clustering algorithm,text clustering,Chinese text

Hierarchical clustering algorithm has low computational efficiency and error accumulation problem in iterative clustering process. To deal with the problems, we propose an improved of hierarchical clustering algorithm based on GAAC (Group-average Agglomerative Clustering), and the improved algorithm is applied to Chinese text clustering. The results of our experimentation show that the improved algorithm have been improved greatly in computational efficiency and the quality of clustering results.
