一种改进的基于遗传和蚁群算法的主题爬虫

Design of genetic and ant algorithms based focused crawler

介绍了一种改进的基于遗传和蚁群算法的主题爬虫的设计。把遗传算法和蚁群算法相结合,可以提高主题爬虫的性能。同时,对选择算子,交叉算子和变异算子进行了优化。整个设计的改进框架是借助于新的URL分析模型进行的。同时,实验结果也表明了新的算法的有效性。

A novel design of the focused crawler based on the genetic and ant algorithms is proposed in this paper. The genetic and ant algorithms are combined together to improve the performance of focused crawler. The selection operator,crossover and mutation operator are optimized. The whole improved frame is funded on the new URL analysis model. And the experimental results show the new algorithm is efficiency.
