Abstract: A meeting was held in Santa Fe, New Mexico, October 21-22, 1999, to generate discussion and consensus about interoperability of publicly available scholarly information archives. The invitees represented several well known e-print and report archive initiatives, as well as organizations with interests in digital libraries and the transformation of scholarly communication. The central goal of the meeting was to agree on recommendations that would make the creation of end-user services such as scientific search engines and linking systems for data originating from distributed and dissimilar archives easier. The Universal Preprint Service (UPS) Prototype was developed in preparation for this meeting. As a proof-of-concept of a multi-discipline digital library of publicly available scholarly material, the Prototype harvested nearly 200,000 records from several different archives and created an attractive end-user environment. This paper describes the results of the project. This is done in two ways. On the one hand, the experimental end-user service that was created during the project is illustrated. On the other hand, the lessons that the project team drew from the experience of creating the Prototype are presented.

  • M. Kholief.Digital Libraries and Education: What and Why?, PACISE’04, California, PA, April 2004.

Abstract: This paper gives an introduction to digital libraries and emphasizes their applications in education. Examples of digital libraries that support education are presented the question of why digital libraries can be useful for education is answered and their possible use to support inquiry-based education in particular is discussed. The paper also presents the issue of how experts’ digital libraries can be adapted by ordinary learners.

  • M. Kholief, K. Maly, S. Shen.Case Study of a Stream-Based Digital Library: Medical Data, ICADL’03, Kuala Lumpur, Malaysia, December 2003.

Abstract:  A case study of a digital library that contains streams and supports event-based retrieval is described. Medical streams that relate to patients having liver tumors are used in the digital library. 3 types of streams were used: computed tomography (CT) scan, medical text, and audio streams. Events, such as lsquoMaximum diameter of the tumorrsquo, were generated and represented in the user interface to enable doctors to retrieve and playback segments of the streams. This paper presents the details of creating the digital library: the data organization, publishing stream data, generating the bibliographic metadata, using events, relating streams, the search engine, and the playback of the streams.

  • M. Kholief, K. Maly, S. Shen.A Medical Streams-Based Digital Library Architecture, JCDL’03, Huston, TX, May 2003.

Abstract: We describe a digital library that contains streams and supports event-based retrieval. Streams used in the digital library are CT scan, medical text, and audio streams. Events, such as ?tumor appeared?, were generated and represented in the user interface to enable doctors to retrieve and playback segments of the streams. This paper concentrates on describing the data organization and the user interface.

Abstract: Data streams are very important sources of information for both researchers and other users. Data streams might be video or audio streams or streams of sensor readings or satellite images. Using digital libraries for archival, preservation, administration, and access control for this type of information greatly enhances the utility of data streams. For this specific type of digital libraries, our proposed event-based retrieval provides an alternate, yet a very natural way of retrieving information. People tend to remember or search by a specific event that occurred in the stream better than by the time at which this event occurred. In this paper we present the analysis and design of a digital library system that contains data streams and supports event-based retrieval.

Abstract: Data streams are a very important source of information for both researchers and ordinary users. Data streams might be video or audio streams or might be a stream of sensor readings, satellite images, etc. Saving data, streams in digital libraries add the advantages of using digital libraries from archival, preservation, administration, access control, etc to this information. For this specific type of digital libraries, event-based retrieval provides an alternative, yet a very natural way of retrieving information. People tend to remember or search by a specific event that happened in the stream better than by the time at which this event happened.In this paper, we describe the organization and services of a prototype digital library system that contains streamed data and enables event-based retrieval from them. We present a preliminary formal definition of data streams and events. We also show some possible applications of this system. We conclude by presenting the ongoing and future extensions to our research.
