Abstract

Several national libraries are collecting parts of the Internet or planning to do so, but in order to render a complete impression of the Internet, web archives must be interoperable, enabling a user to make seamless searches. A questionnaire on this issue was sent to 95 national libraries. The answers show agreement with this goal and that web archiving is becoming more common. Partnering is a key ingredient in moving forward and a useful distinction is suggested in the labels curatorial partners (archives, museums) and technical partners (private companies, universities, other research institutions). Working with private, for-profit companies may also force national libraries to leave room for unorthodox thinking and experimenting. The biggest challenge right now is to make legal deposit, copyright and other legislation adapt to an Internet world, so we can preserve it and make it available to present and future generation.

Abstract

The BAER Web Resources Group was charged in October 1999 with defining and describing the parameters of electronic resources that do not clearly belong to the categories being defined by the BAER Digital Group or the BAER Electronic Journals Group. After some difficulty identifying precisely which resources fell under the Group's charge, we finally named the following types of resources for our consideration: web sites, electronic texts, indexes, databases and abstracts, online reference resources, and networked and non-networked CD-ROMs. Electronic resources are a vast and growing collection that touch nearly every department within the Library. It is unrealistic to think one department can effectively administer all aspects of the collection. The Group then began to focus on the concern of bibliographic access to these varied resources, and to define parameters for handling or processing them within the Library. Some key elements became evident as the work progressed. * Selection process of resources to be acquired for the collection * Duplication of effort * Use of CORC * Resource Finder design * Maintenance of Resource Finder * CD-ROMs not networked * Communications * Voyager search limitations. An unexpected collaboration with the Web Development Committee on the Resource Finder helped to steer the Group to more detailed descriptions of bibliographic access. This collaboration included development of data elements for the Resource Finder database, and some discussions on Library staff processing of the resources. The Web Resources Group invited expert testimony to help the Group broaden its view to envision public use of the resources and discuss concerns related to technical services processing. The first testimony came from members of the Resource Finder Committee. Some background information on the Web Development Resource Finder Committee was shared. The second testimony was from librarians who select electronic texts. Three main themes were addressed: accessing CD-ROMs; the issue of including non-networked CD-ROMs in the Resource Finder; and, some special concerns about electronic texts. The third testimony came from librarians who select indexes and abstracts and also provide Reference services. Appendices to this report include minutes of the meetings with the experts (Appendix A), a list of proposed data elements to be used in the Resource Finder (Appendix B), and recommendations made to the Resource Finder Committee (Appendix C). Below are summaries of the key elements.

Rez. in: ZfBB 51(2004) H.2, S.116-118 (H. Jüngling): "Das überspitzt gezeichnete Bild vom Ingenieur,der nur mit Rechenschieber und Zeichenbrett ausgestattet und ohne weitere Hilfsmittel im stillen Kämmerlein erfolgreich neue, nützliche Maschinen konstruiert, stimmt schon lange nicht mehr. Zwar haben Ingenieure die Unterstützung durch moderne Rechner in der täglichen Praxis nicht nur gerne und zügig schätzen gelernt, sie waren sogar häufig Vorreiter bei deren (Weiter-)Entwicklung und Nutzung. Zur Beschaffung von Informationen jedweder Art wurden Rechner dagegen zunächst überaus zögerlich angenommen und gewannen - wie allerdings in vielen anderen Wissenschaftsbereichen auch -für diese Verwendung im Grunde erst durch die Möglichkeiten des Internets an Akzeptanz und Bedeutung. Erste Initiativen, dem möglicherweise spezifischen Informationsbedarf von Ingenieuren entgegenzukommen und der Engineering Community »runde« Angebote zu machen, gehen auf die Mitte der 90er-Jahre zurück. So sind 1994/95 u.a. die Engineering Electronic Library, Sweden (EELS, 1994),2 das Engineering Village von Engineering Information Inc., NewYork (1995)3 und die Edinburgh Engineering Virtual Library (EEVL, 1995)4 entstanden. Zum Vergleich sei angemerkt, dass konkrete Planungen für die Virtuelle Fachbibliothek Technik (ViFaTec)s der TIB/DFG erst 1997/98 einsetzten. Nach anfänglicher Euphorie hat sich bekanntermaßen relativ schnell gezeigt, dass derartige Angebote trotz teilweise überregionaler Zusammenarbeit nicht ohne erheblichen finanziellen Aufwand zu kreieren und vor allem aufrecht zu erhalten und zu pflegen sind.So hat z.B.die zweite Generation des Engineering Village von früheren, relativ hoch gesteckten Zielen Abstand genommen. Die EELS hat ihr Angebot bereits vor etwa einem Jahr »eingefroren«. Dagegen scheint die EEVL noch immer recht lebendig zu sein. U. a. deshalb soll hier näher darauf eingegangen werden. ..."

Abstract

This is the second part of two articles about reference linking in hybrid digital libraries. The first part, Frameworks for Linking described the current state-of-the-art and contrasted various approaches to the problem. It identified static and dynamic linking solutions, as well as open and closed linking frameworks. It also included an extensive bibliography. The second part describes our work at the University of Ghent to address these issues. SFX is a generic linking system that we have developed for our own needs, but its underlying concepts can be applied in a wide range of digital libraries. This is a description of the approach to the creation of extended services in a hybrid library environment that has been taken by the Library Automation team at the University of Ghent. The ongoing research has been grouped under the working title Special Effects (SFX). In order to explain the SFX-concepts in a comprehensive way, the discussion will start with a brief description of pre-SFX experiments. Thereafter, the basics of the SFX-approach are explained briefly, in combination with concrete implementation choices taken for the Elektron SFX-linking experiment. Elektron was the name of a modest digital library collaboration between the Universities of Ghent, Louvain and Antwerp.

Abstract

More and more libraries starting semantic web projects. The question about the license of the data is not discussed or the discussion is deferred to the end of project. In this paper is discussed why the question of the license is so important in context of the semantic web that is should be one of the first aspects in a semantic web project. Also it will be shown why a public domain weaver is the only solution that fulfill the the special requirements of the semantic web and that guaranties the reuseablitly of semantic library data for a sustainability of the projects.

Abstract

I describe a set of automated archives for electronic communication of research information in many fields of physics, and some related and unrelated disciplines, starting from 1991. These archives now serve over 35.000 users worldwide from over 70 countries, and process more than 70.000 electronic transaction per day. In some fields of physics, they have already supplanted traditional research journals as conveyors of both topical and archival research information

Enthält die Bemerkung: "The problems of indexing and categorization of information in principle lie within the purview of library and information science communities, but to date theirs has been a curiously low profile in the electronic realm, while various amateur brute-force indexing schemes are running dangerously amok. It would be remarkable if centuries of ostensibly relevant experience will find little applicability in the network context"

Abstract

Purpose: To provide a critical review of Bergman's 2001 study on the Deep Web. In addition, we bring a new concept into the discussion, the Academic Invisible Web (AIW). We define the Academic Invisible Web as consisting of all databases and collections relevant to academia but not searchable by the general-purpose internet search engines. Indexing this part of the Invisible Web is central to scien-tific search engines. We provide an overview of approaches followed thus far. Design/methodology/approach: Discussion of measures and calculations, estima-tion based on informetric laws. Literature review on approaches for uncovering information from the Invisible Web. Findings: Bergman's size estimate of the Invisible Web is highly questionable. We demonstrate some major errors in the conceptual design of the Bergman paper. A new (raw) size estimate is given. Research limitations/implications: The precision of our estimate is limited due to a small sample size and lack of reliable data. Practical implications: We can show that no single library alone will be able to index the Academic Invisible Web. We suggest collaboration to accomplish this task. Originality/value: Provides library managers and those interested in developing academic search engines with data on the size and attributes of the Academic In-visible Web.

Abstract

The creation of services linking related information entities is an area that is attracting an ever increasing interest in the ongoing development of the World Wide Web in general, and of research-related information systems in particular. Currently, both practice and theory point at linking services as being a major domain for innovation enabled by digital communication of content. Publishers, subscription agents, researchers and libraries are all looking into ways to create added value by linking related information entities, as such presenting the information within a broader context estimated to be relevant to the users of the information. This is the first of two articles in D-Lib Magazine on this topic. This first part describes the current state-of-the-art and contrasts various approaches to the problem. It identifies static and dynamic linking solutions as well as open and closed linking frameworks. It also includes an extensive bibliography. The second part, SFX, a Generic Linking Solution describes a system that we have developed for linking in a hybrid working environment. The creation of services linking related information entities is an area that is attracting an ever increasing interest in the ongoing development of the World Wide Web in general, and of research-related information systems in particular. Although most writings on electronic scientific communication have touted other benefits, such as the increase in communication speed, the possibility to exchange multimedia content and the absence of limitations on the length of research papers, currently both practice and theory point at linking services as being a major opportunity for improved communication of content. Publishers, subscription agents, researchers and libraries are all looking into ways to create added-value by linking related information entities, as such presenting the information within a broader context estimated to be relevant to the users of the information.

Abstract

This second edition is an update and expansion of the original April 1998 edition. It contains more of everything. In particular, the resources section has been expanded and updated. This document is designed to help those who are contemplating setting up a digital library. Whether this is a first time computerization effort or an extension of an existing library's services, there are questions to be answered, deci-sions to be made, and work to be done. This document covers all those stages and more. The first section (Chapter 1) is a series of questions to ask yourself and your organization. The questions are designed generally to raise issues rather than to provide definitive answers. The second section (Chapters 2-5) discusses the planning and implementation of a digital library. It raises some issues which are specific, and contains information to help answer the specifics and a host of other aspects of a digital li-brary project. The third section (Chapters 6 -7) includes resources and a look at current research, existing digital library systems, and the future. These chapters enable you to find additional resources and help, as well as show you where to look for interesting examples of the current state of the art

Abstract

This is the third part of our papers about reference linking in a hybrid library environment. The first part described the state-of-the-art of reference linking and contrasted various approaches to the problem. It identified static and dynamic linking solutions, open and closed linking frameworks as well as just-in-case and just-in-time linking. The second part introduced SFX, a dynamic, just-in-time linking solution we built for our own purposes. However, we suggested that the underlying concepts were sufficiently generic to be applied in a wide range of digital libraries. In this third part we show how this has been demonstrated conclusively in the "SFX@Ghent & SFX@LANL" experiment. In this experiment, local as well as remote distributed information resources of the digital library collections of the Research Library of the Los Alamos National Laboratory and the University of Ghent Library have been used as starting points for SFX-links into other parts of the collections. The SFX-framework has further been generalized in order to achieve a technology that can easily be transferred from one digital library environment to another and that minimizes the overhead in making the distributed information services that make up those libraries interoperable with SFX. This third part starts with a presentation of the SFX problem statement in light of the recent discussions on reference linking. Next, it introduces the notion of global and local relevance of extended services as well as an architectural categorization of open linking frameworks, also referred to as frameworks that are supportive of selective resolution. Then, an in-depth description of the generalized SFX solution is given.

Abstract

Ontologies are currently a buzzword in many communities, hailed as a mechanism for making better use of the Web. They offer a shared definition of a domain that can be understood by computers, enabling them to complete more meaningful tasks. Although ontologies of different descriptions have been in development and use for some time, it is their potential as a key technology in the Semantic Web which is responsible for the current wave of interest. Communities have different expectations of the Semantic Web and how it will be realised, but it is generally believed that ontologies will play a major role. In light of their potential in this new context, much current effort is focusing an developing languages and tools. OWL (Web Ontology Language) has recently become a standard, and builds an top of existing Web languages such as XML and RDF to offer a high degree of expressiveness. A variety of tools are emerging for creating, editing and managing ontologies in OWL. Ontologies have a range of potential benefits and applications in further and higher education, including the sharing of information across educational systems, providing frameworks for learning object reuse, and enabling intelligent and personalised student support. The difficulties inherent in creating a model of a domain are being tackled, and the communities involved in ontology development are working together to achieve their vision of the Semantic Web. This Technology and Standards Watch report discusses ontologies and their role in the Semantic Web, with a special focus an their implications for teaching and learning. This report will introduce ontologies to the further and higher education community, explaining why they are being developed, what they hope to achieve, and their potential benefits to the community. Current ontology tools and standards will be described, and the emphasis will be an introducing the technology to a new audience and exploring its risks and potential applications in teaching and learning. At a time when educational programmes based an ontologies are starting to be developed, the author hopes to increase understanding of the key issues in the wider community.

"Ontologies promise "a shared and common understanding of a domain that can be communicated between people and application systems" [1]. They attempt to formulate a thorough and rigorous representation of a domain by specifying all of its concepts, the relationships between them and the conditions and regulations of the domain. Ontologies can express hierarchical links between entities as well as other semantic relations. An example of part of an ontology is provided in Figure 1, in which it is specified not only that an author is a person and that a book is a publication, but also that an author writes a book and that a book has chapters."

Abstract

This paper presents findings from a study of how knowledge workers use the Web to seek external information as part of their daily work. 34 users from 7 companies took part in the study. Participants were mainly IT-specialists, managers, and research/marketing/consulting staff working in organizations that included a large utility company; a major bank, and a consulting firm. Participants answered a detailed questionnaire and were interviewed individually in order to understand their information needs and information seeking preferences. A custom-developed WebTracker software application was installed on each of their work place PCs, and participants' Web-use activities were then recorded continuously during two-week periods

Abstract

DOI-X is a prototype metadata database designed to support DOI lookups. The prototype is intended to address the integration of metadata registration and maintenance with basic DOI registration and maintenance, enabling publishers to use a single mechanism and a single quality-assurance process to register both DOIs and their associated metadata. It also contains the lookup mechanisms necessary to access the journal article metadata, both on a single-item lookup basis and on a batch basis, such as would facilitate reference linking. The prototype database was introduced and demonstrated to attendees at the STM International Meeting and the Frankfurt Book Fair in October 1999. This paper discusses the background for the creation of DOI-X and its salient features.
