abstract

Digital library is a new term but widely known as an important issue to make information super-highways really work. Digital library researches have been launched in many countries. For examples, in USA, NSF/NASA/ARPA have started their grant for digital libray researches in 1994, and in UK, JISC has started their research funding program for digital libraries.
Digital library, which is called "Wall-less Library", will provide us with the Space of Information where we can seamlessly access information from our own terminals. The research area of digital libraries covers various aspects from computer/network technologies to social aspects. This paper describes backgrounds of digital libraries and discusses several technological aspects related to digital libraries.

Abstract

B-ISDN, a revolutionary information and telecommunication infrastructure for the next century, is capable of simultaneously transmitting multimedia information composed of sound, image, text and HDTV signal. Its transmission capacity is 100 times that of N-ISDN.
The Association of Broadband-ISDN Business chance & Culture Creation(BBCC), the first Japanese organization to conduct application research and experiments in B-ISDN, opened its laboratory to the public on July 8th, 1994. Through its activities, the BBCC promotes B-ISDN and proves its social utility, while developing and experimenting with new applications indispensable to a fully advanced information society.
In this talk, the outline of application projects is introduced.

Abstracts

First, general functions of digital library system are discussed. Second, necessary functions for information retrieval system to full-text data are investigated. Third, three experimental systems: a system for information retrieval by query sentences, a system for keywords translation, and a system for automatic combination classification numbers are presented which are developed by the author. The first two systems are now operated as demonstration systems in the BBCC project which is the B-ISDN Business chance & Culture Creations project in Japan. Finally, some problems which must be solved to realize a digital library system are presented.

Abstract

This paper suggests that document structure extraction and abstract generation are fundamental functions of a digital library. A digital library should have an effective document retrieval facility. In a document, several information axises can be defined: a title, section, paragraph, background, purpose, conclusion, etc. A document structure represents such information axes. The document structure is automatically extracted from a full-text, and is used for generating abstracts to realize effective document retrieval.

Abstract

Collaboration support tools with well-designed user interfaces are essential to provide library users with good environments for their intellectual activities. This paper describes a collaboration support tool and an OPAC which has a bookshelf-like graphical user interface. The collaboration support tool is composed of a TV-phone, a shared virtual display, a white board and an image tool. A user and a librarian can talk with each other via the collaboration tool looking at books displayed on a virtual bookshelf together. We evaluated the applicability of the system by applying it to the reference service that a librarian instructs a user to learn operations of a GUI-based OPAC, which is in operation in our university. We applied this experiment to 30 testees, and got the positive result from the answers of the questionares given to the testees.
