摘要:

主题搜索引擎的研究难点之一就是主题与网页信息之间的准确匹配.通过对网页的特征进行分析,提取网页特征中的主题特征词,并用提取的主题特征词表示网页主题信息,提出了利用网页特征及特征之间的关系来建立网页特征模型.该特征模型能准确地描述网页的内部特征和外部特征的主题表现力,有利于计算网页与主题之间的相似度.实验结果表明该特征模型能有效地表达网页的主题信息,并有助于提高主题搜索引擎的资源发现率和搜索准确率

Abstract:

In focused search engine research,a difficult point is the precise match between theme and Web page. After analyzing the fea-tures,extract the theme feature words from Web pages,and take the theme feature words as Web page theme information,a method of u-sing the Web page features to build Web feature mode is proposed. The feature model can accurately describe the subject of internal fea-tures and external features of the Web's expression,and is beneficial to calculate the similarity between Web pages and themes. The result of the experiment shows that Web feature model can effectively express the Web page theme,and contribute to improve the search re-source discovery rate and accuracy rate of the focused search engine
