Focusing on the problem that the ant colony algorithm gets into stagnation easily and cannot fully search in solution space
a text clustering approach based on fusion of ant colony and genetic algorithm is proposed. The four parameters which influence the performance of ant colony algorithm are encoded as chromosomes
thereby the fitness function
selection
crossover and mutation operator are designed to find the combination of optimal parameters through a number of iterations
and then it is applied to text clustering. The simulation results show that compared with the classical k-means clustering and the basic ant colony clustering algorithm
the proposed algorithm has better performance and the value of F-measure is enhanced by 5.69%
48.60% and 69.60% respectively in 3 test data sets. Therefore it is more suitable for processing larger datasets.
