With the number and types of documents in digital library systems incr easing, tools for automatically organizing and presenting the content have to be found. While many approaches focus on topic-based organization and structuring, hardly any system ...

Text categorization is typically formulated as a concept learning prob lem where each instance is a single isolated document. In this paper we are interested in a more general formulation where documents are organized as page sequences, as naturally ...

This paper describes a system for the automated assignment of authoriz ed names. A collaboration between a computer scientist and a librarian, the system provides for enhanced end-user searching of digital libraries without increasing drastically the ...

We propose a novel approach for automatic generation of topically-rela ted events from multi-lingual news sources. Named entity terms are extracted automatically from the news content. Together with the content terms, they constitute the basis of ...

A service is described to help enable digital libraries for education, such as the NSDL, to serve as collaboration spaces for the creation, modification and use of active learning experiences. The goal is to redefine the line between those activities ...

We believe that an important category of SMET digital library content will be highly interactive, explorable microworlds for teaching science, mathematics, and engineering concepts. Such environments have proved extraordinarily time-consuming and ...

In this paper we report the findings from a field study of legal resea rch in a first-tier law school and on the resulting redesign of XLibris, a next-generation e-book. We first characterize a work setting in which we expected an e-book to be a useful ...

The Open Archives Initiative [www.openarchives.org] has developed a me tadata harvesting protocol to further its aim of efficient dissemination of content through interoperability standards. In early 2001, at meetings in the U.S. and Europe, the version ...

Interoperability is a fundamental challenge for networked information discovery and retrieval. Often treated monolithically in the literature, interoperability is multifaceted and can be analyzed into different types and levels. This paper discusses an ...

This short paper describes the construction and application of Cross-D omain Information Servers using features of the standard Z39.50 information retrieval protocol[11]. We use the Z39.50 Explain Database to determine the databases and indexes of a ...

The Open Archives Initiative (OAI) develops and promotes interoperabil ity solutions that aim to facilitate the efficient dissemination of content. The roots of the OAI lie in the E-Print community. Over the last year its focus has been extended to ...

The Open Archives Initiative (OAI) is an organization dedicated to sol ving problems of digital library interoperability by defining simple protocols, most recently for the exchange of metadata. The success of such an activity requires vigilance in ...

The usefulness of the many on-line journals and scientific digital lib raries that exist today is limited by the lack of a service that can federate them through a unified interface. The Open Archive Initiative (OAI) is one major effort to address ...

Increasingly, digital libraries are being defined that collect pointers to World-Wide Web based resources rather than hold the resources themselves. Maintaining these collections is challenging due to distributed document ownership and high fluidity. ...

We describe the preliminary results from a pilot study, which assessed the perceived reputation - authority and trustworthiness - of the output from five WWW indexing/ranking tools. The tools are based on three techniques: external link structures, ...

Searching for useful information on the World Wide Web has become incr easingly difficult. While Internet search engines have been helping people to search on the web, low recall rate and outdated indexes have become more and more problematic as the web ...

In this paper, we describe Salticus, a web crawler that learns from us ers web browsing activity. Salticus enables users to build a personal digital library by collecting documents and generalizing over the user's choices.

This panel is organized to share the experience gained and lessons lea rned in developing cutting-edge technology applications and digital libraries when different cultures meet together. “Culture”ù is interpreted in different ways and different ...

Naturally, digital library systems focus principally on the reader: th e consumer of the material that constitutes the library. In contrast, this paper describes an interface that makes it easy for people to build their own library collections. ...

The DL offers the possibility of collaborative scholarship, but the ap propriate tools must be integrated within the DL to serve this purpose. We propose a Web-based tool to guide controlled data annotations that link items in the DL to a domain-...

Silver is an authoring tool that aims to allow novice users to edit di gital video. The goal is to make editing of digital video as easy as text editing. Silver provides multiple coordinated views, including project, source, outline, subject, storyboard,...

This paper introduces Videograph, a new tool for video mining and visu alizing the structure of the plot of a video sequence. The main idea is to “stitch” together similar scenes which are apart in time. We give a fast algorithm to do stitching and we ...

This note summarizes the system development activities of the Alexandr ia Digital Earth Prototype (ADEPT) Project.5 ADEPT and the Alexandria Digital Library (ADL) are, respectively, the research and operational components of the Alexandria Digital ...

This paper reviews considerations associated with implementing the Ale xandria Digital Earth Prototype (ADEPT) in undergraduate geography education by means of Iscapes (or Information landscapes). In particular, we are interested in how Iscapes might ...

This paper describes a new project funded in the UK by the Joint Infor mation Systems Committee, to develop a virtual learning environment which combines a new awareness of internet sources such as bibliographic databases and full-text electronic ...

In this paper, we describe the NBDL (National Biology Digital Library) project, one of the six CIS (Core Integration System) projects of the NSF NSDL (National SMETE Digital Library) Program.

The potential of automatically generated indexes for information acces s has been recognized for several decades (e.g., Bush 1945 [2], Edmundson and Wyllys 1961 [4]), but the quantity of text and the ambiguity of natural language processing have made ...

Digital libraries and their user communities are increasingly internat ional in nature. However - though technological progress and global education have brought American and European communities closer - cross-cultural and other crosscutting issues ...

The Internet has considerably empowered libraries and changed common p erception of what they entail. Public libraries, in particular, are using technological advancements to expand their range of services and enhance their civic roles. Providing ...

The UKs development of a Distributed National Electronic Resource (DNE R) is being subjected to intensive formative evaluation by a multi-disciplinary team. In this paper the Project Director reports on initial actions designed to characterise the DNER ...
