A novel method for text categorization,which is based on boosting fuzzy classification,was proposed in the paper.Latent Semantic Index(LSI) was used to select text feature and then Boosting algorithm was proposed to integrate fuzzy classification.In each iteration training of boosting algorithm,the distribution of training instances was adjusted,and classification rules were created by genetic algorithm.The weights of the training instances that were classified correctly by available rules were reduced,so that the new fuzzy rule focuses on the misestimate or uncovered instances.Experimental results show that classifier based on fuzzy classification is effective and efficient.
