我们参加了NTCIR-5 WEB导航检索子任务(Navi-2),以通过使用仅索引锚文本而不是网页全文的检索系统来验证锚文本索引的最有效检索方法。我们引入了结合六种检索度量中的一种或多种的检索方法:(a)锚定频率(af),(b)参考一致性(rc),(c)查询权重(qw),(d)页面代表性(rep),(e)站点相关性(sr)和(f)逆锚定文档频率(iadf)。实验结果表明:(1)可以看出,仅使用锚频率进行锚文本索引的检索方法比仅使用网页全文索引的检索方法更有效;(2)包含sr或iadf的检索方法对于锚文本索引是有效的,并且sr比iadf更有效。关键词:锚文本、导航检索、站点相关性
We participated in NTCIR-5 WEB Navigational Retrieval Subtask(Navi-2) in order to verify the most effective retrieval method for the index of anchor texts by using a retrieval system that indexed only anchor texts instead of full texts of Web pages. We introduced retrieval methods that combine one or more of six retrieval measures: (a) anchor frequency (af), (b) reference consistency (rc), (c) query weight (qw), (d) page representativeness (rep), (e) site relevancy (sr), and (f) inverse anchor document frequency (iadf). The experimental results revealed that: (1) it could be implied that the retrieval method that used only anchor frequency for the index of anchor texts was more effective than the retrieval method for the index of only full texts of Web pages, and that (2) the retrieval method that contained sr or iadf was effective for the index of anchor texts, and that sr was more effective than iadf.
