摘　　要：以鳜鱼基因克隆为例,揭示了基于生物信息学的知识发现的全过程。利用Entrez、SRS等检索工具从GenBank、EMBL等核酸序列数据库、鱼类专业数据库获取相关鱼类的基因等信息,采用半经验值直观算法,以BLAST、FASTA方法结合Taxonomy分类数据库,选择恰当的过滤程序过滤掉效数据,最终获得与知识发现预期结果一致知识。The whole process of the knowledge discovery based on the bioinformatics has been showed by the example of gene cloning of Siniperca chuatsi. The gene information of related fishes are got from the nuclei acid databases of GenBank, EMBL and the fish databases using the retrieval tools of Entrez and SRS. The arithmetic method of half experience value has been adopted. The methods of BLAST and FASTA are combined with the classification database of Taxonomy. The adequacy filtration programs are selected to filtrate the inefficacy data. Finally, the knowledge consistent with expect result of knowledge discovery are got.
