In the retrieval of newspapers or weblogs in which particular terms and expressions are used frequently, it is not easy to remind the user of appropriate query terms. For this case, it is necessary to present typical feature terms or documents in the document set without depending on the user’s input. In this paper, we propose the navigation system ‘S-node’ for documents. The system extracts two kinds of words that show exhaustivity or specificity from documents written in Japanese based on repetition index, and constructs hyperlinks between documents that can reach as short as possible to various documents based on co-occurrence of terms. We describe the implementation of the system, and the results of evaluation.
