【摘要】 针对目前互联网信息资源广泛、网页结构复杂、噪音信息较多的现状,主题爬虫获取有效信息过程中精确度低、耗费时间长等问题。结合经典的Hopfield算法,提出了针对网页结构特征进行分块的主题爬行改进算法,实验证明该改进算法在一定程度上能有效地解决目前信息获取过程中所面临的问题。更多还原

【Abstract】 As the Web continues to grow,it has become increasingly obvious that information overload and is terribly noisy.In this paper,to address such issues as low precision,much time-consumption,we present an improved Hopfield algorithm orienting web page structure feature.The experimental results show that the proposed approach is practical.更多还原
