Abstract:

Clustering analysis with ant colony optimization (ACO) is presented by Deneubourg in 1991 and has been used widely. In this paper, a mechanism of the  best solution kept is presented to improve the performance of clustering analysis with ACO further. Two indices are chosen to valide the new algorithm. Two experiments in the datasetIris and the text dataset show that the new algorithm has better performance.

Key words: text clustering, ant colony algorithm, clustering with ACO, text mining
