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.
