英文摘要：

As a novel simulated evolutionary computation technology, swarm intelligence has shown its performance in solving complex optimization problem. This paper introduces and discusses the application of ACO and PSO in Knowledge Discovery in Database（KDD）. The basic principle and characteristics of the algorithms are addressed in the paper. Finally, some problems to be solved are mentioned.
