Research on Text Clustering Algorithm Based on K_means and SOM
Xinwu Li · 2008
Text clustering is one of the difficult and hot research fields in the Internet search engine research. Combination the advantages of k-means clustering and self-organizing model (SOM) techniques, a new text clustering algorithm is presented. Firstly, texts are preprocessed to satisfy succeed process. Then, the paper analyzes common k-means clustering algorithm and SOM algorithm and combines them to overcome efficiency of low stability of k-means algorithm which is very sensitive to the initial cluster center and the isolated point text. The experimental results indicate that the improved algorithm has a higher accuracy and has a better stability, compared with the original algorithm.
