This paper describes the design and characteristics of a test collection for navigational retrieval of WWW data that was built through the WEB Task of the Fourth NTCIR Workshop to evaluate the retrieval effectiveness of Web search systems. This reusable test collection consists of 100 gigabytes of Web document data and 300 topics of various types and corresponding relevance judgments. Among the several types of ‘Navigational Retrieval,’ we selected the ‘Known Item Search,’ which simulates a situation where a user searches for one or a few ‘representative Web pages’ of a known item. It is assumed that the user knows about the item but may not have seen its Web page. Relevance judgments were performed on the probable documents mainly from the viewpoint of representativeness of respective known items represented by the topics. Using the judgment results, several evaluation measures were applied to various retrieval results. Based on the evaluation results, relationships among the types of topics, Web-page styles and search methods are discussed. The stability of the evaluation results with different numbers of topics is also analyzed.

The National Institute of Informatics (NII) has been conducting joint research with JapanTelecom to develop a 40 Gbps optical transport system for the next-generation SuperSINET. We report on the recent results of field trials focused on automatic chromatic dispersion compensation and path protection/restoration applied to the future SuperSINET as key technologies required to maintain the quality of transmission, to reduce operational costs, and to facilitate the enhancement of network capabilities. From the results of the field trial, we have confirmed that an automatic optical path control system is essential in an all-optical wavelength path network.
