Askhoj, Jan, Nagamori, Mitsuharu and Sugimoto, Shigeo (2011): Archiving as a service: a model for the provision of shared archiving services using cloud computing. In: Proceedings of the 2011 iConference 2011. pp. 151-158. Available online
In this paper, we define some of the characteristics of archiving in a cloud computing environment. Based on these, we describe a model for a cloud archiving system using concepts and information types from the OAIS reference model. The proposed model allows the sharing of functionality and information objects by making these available as services to above layers. The model covers the entire document lifecycle, making archive functionality such as preservation planning possible at an early stage in the document lifecycle, helping to simplify records transfer. Finally, we use our model in a case study, using the records transfer process from Japanese government agencies to the National Archives of Japan as an example.

Morishima, Atsuyuki, Nakamizo, Akiyoshi, Iida, Toshinari, Sugimoto, Shigeo and Kitagawa, Hiroyuki (2009): Why are moved web pages difficult to find?: the WISH approach. In: Proceedings of the 2009 International Conference on the World Wide Web 2009. pp. 1117-1118. Available online
This paper addresses the problem of finding new locations of moved Web pages. We discuss why the content-based approach has a limitation in solving the problem and why it is important to exploit the knowledge on where to search for the pages.

Morishima, Atsuyuki, Nakamizo, Akiyoshi, Iida, Toshinari, Sugimoto, Shigeo and Kitagawa, Hiroyuki (2009): Bringing your dead links back to life: a comprehensive approach and lessons learned. In: Proceedings of the 20th ACM Conference on Hypertext and Hypermedia 2009. pp. 15-24. Available online
This paper presents an experimental study of the automatic correction of broken (dead) Web links focusing, in particular, on links broken by the relocation of Web pages. Our first contribution is that we developed an algorithm that incorporates a comprehensive set of heuristics, some of which are novel, in a single unified framework. The second contribution is that we conducted a relatively large-scale experiment, and analysis of our results revealed the characteristics of the problem of finding moved Web pages. We demonstrated empirically that the problem of searching for moved pages is different from typical information retrieval problems. First, it is impossible to identify the final destination until the page is moved, so the index-server approach is not necessarily effective. Secondly, there is a large bias about where the new address is likely to be and crawler-based solutions can be effectively implemented, avoiding the need to search the entire Web. We analyzed the experimental results in detail to show how important each heuristic is in real Web settings, and conducted statistical analyses to show that our algorithm succeeds in correctly finding new links for more than 70% of broken links at 95% confidence level.

Sakaguchi, Tetsuo, Maeda, Akira, Fujita, Takehisa, Sugimoto, Shigeo and Tabata, Koichi (1996): A Browsing Tool of Multi-Lingual Documents for Users without Multi-Lingual Fonts. In: DL96: Proceedings of the 1st ACM International Conference on Digital Libraries 1996. pp. 63-71. Available online
Since a library is inherently multi-lingual, a multi-lingual document environment is crucial for a digital library. In the near future, worldwide information sharing through digital libraries will be common. Currently, multi-lingual documents are poorly facilitated on computers and the Internet. It is impractical to consider installing fonts for all character sets in every user's terminal. This paper presents a multi-lingual document browsing tool for a user with no multi-lingual fonts on his or her terminal. It discusses several methods for browsing multi-lingual documents and proposes a browser which sends a text string with the font glyphs required to display the text. It also gives the evaluation result of the browser.

Tabata, Koichi and Sugimoto, Shigeo (1989): A Knowledge-Based System with Audio-Visual Aids. In Interacting with Computers, 1 (3) pp. 245-258.
A Knowledge-based System with Audio-Visual Aids (KS/AV) is presented. KS/AV is a knowledge-based system that has multiple types of knowledge represented not only in symbols but in audio-visual (AV) images, and it provides an environment for human-machine communication through AV media. We define a predicate logic based on objects for knowledge representation in KS/AV. It is a first order predicate logic in which every individual is regarded as an object. All of the individuals including AV images are regarded as objects. Their definitions are based on the class concepts of Smalltalk-80. AV image objects presented in this paper include not only simple video and graphic images, but also composite images that consist of several component images. This paper presents the KS/AV system developed on a small computer system with various AV equipment. As a case study, we developed a reading advisory system for children on KS/AV, which communicates with children through AV images and gives their favourite picture books.
