Abstract: Focusing on the problem that the Fuzzy C-Means clustering algorithm is sensitive to initial centers and input order，a document clustering algorithm combined with ant colony clustering and Fuzzy C-Means is proposed.The algorithm takes advantages of ant colony clustering algorithm to find the initial centers，then uses Fuzzy C-Means to get the accurate result.Experimental results show the good performance of the hybrid document clustering algorithm，and it is better for the large-sized dataset.
