Abstract

Libraries have had web presences since the introduction of the World Wide Web. Providing access to information provided by the library has been attempted through various means throughout the years but no method has been as popular or pervasive as the uses of library gateways and portals. Development of gateways and portals in libraries has been affected by many factors many of which have been outside the direct control of libraries or librarians. Both the history of library practice in this area and these external factors have had a substantial impact on the state of library portal and gateway development today.

Abstract

With the development of the World Wide Web, the "information search" has grown to be a significant business sector of a global, competitive and commercial market. Powerful players have entered this market, such as commercial internet search engines, information portals, multinational publishers and online content integrators. Will Google, Yahoo or Microsoft be the only portals to global knowledge in 2010? If libraries do not want to become marginalized in a key area of their traditional services, they need to acknowledge the challenges that come with the globalisation of scholarly information, the existence and further growth of the academic internet

Abstract

With the recent rapid diffusion over the international computer networks of world-wide distributed document bases, the question of multilingual access and multilingual information retrieval is becoming increasingly relevant. We briefly discuss just some of the issues that must be addressed in order to implement a multilingual interface for a Digital Library system and describe our own approach to this problem.

Abstract

Information subject gateways provide targeted discovery services for their users, giving access to Web resources selected according to quality and subject coverage criteria. Information gateways recognise that they must collaborate on a wide range of issues relating to content to ensure continued success. This report is informed by discussion of content activities at the 1999 Imesh Workshop. The author considers the implications for subject based gateways of co-operation regarding coverage policy, creation of metadata, and provision of searching and browsing across services. Other possibilities for co-operation include working more closely with information providers, and diclosure of information in joint metadata registries

Content

"Wissenschaftler brauchen fundierte Informationen aus Quellen, auf die man sich verlassen kann. Die Suche nach solchen Quellen, wissenschaftlichen Aufsätzen, Dissertationen, Büchern, Datenbanken und Linklisten gestaltete sich bislang schwierig: Bibliotheken oder Verlage von Fachzeitschriften mussten einzeln angesteuert werden, einen zentralen, einheitlichen und einfachen Zugang gab es bislang, nicht. Das soll sich jetzt ändern: Das vom Bundesministerium für Bildung und Forschung (BMBF) und von der Deutschen; Forschungsgemeinsehaft (DFG) geförderte Internetportal "vascoda", das nach dem Willen seiner Initiatoren auch Grundbaustein für die "Digitale Bibliothek Deutschland" sein soll, will Forschern Zugang zu wissenschaftlicher Information unterschiedlichster Fachrichtungen und unterschiedlichster Formate bieten. Das ist bundesweit in dieser Form ebenso einzigartig wie die Tatsache, dass die an vascoda angeschlossenen Datenbanken ausschließlich ;,geprüfte" Informationen liefern sollen: "Fachbibliothekare und Fachwissenschaftler der Anbieter, die sich unter dem vascoda-Dach zusammengeschlossen haben, prüfen, welche Texte vdrfügbar gemacht werden", sagt Christine Burblies von der vascoda-Geschäftsstelle in Hannover. "So können wir gewährleisten, dass die Informationen wissenschaftlichen Ansprüchen genügen." Das macht dann auch den wesentlichen Unterschied zu anderen Suchmaschinen aus: Die Suchmaske des Wissenschaftsportals ist zwar ähnlich einfach zu handhaben wie die Internet-Suchmaschine Google - vascoda verirrt sich aber nicht im World Wide Web. Und während andere Internet-Suchmaschinen nicht den Zugriff auf das so genannte "invisible web" bieten, also beispielsweise auf Bibliothekskataloge, ermöglicht vascoda auch den Zugriff auf dieses unsichtbare Netz. Das Wissenschaftsportal ist unentgeltlich nutzbar, und auch ein Großteil der Informationen ist kostenlos zu beziehen. Es sind aber auch kostenpflichtige Informationen verfügbar - zum Beispiel aus Verlagsangeboten und kommerziellen Datenbanken. Wer Informationen etwa zu soziologischen Fragen sucht, landet sicher auch auf den Internetseiten des Instituts für Soziologie in Darmstadt (www.ifs.tu-darmstadt.de/forsch.htm), das ebenso zu den vascoda-Anbietern gehört wie das Deutsche Institut für Internationale Pädagogik (DIPF) in Frankfurt (www.dipfde/index_1024.htm). In vascoda eingebunden sind zur Zeit 23 virtuelle Fachbibliotheken (ViFas), die vier großen Informationsverbünde EconDoc (Wirtschaft), GetInfo (Naturwissenschaften und Technik), infoconnex (Pädagogik, Sozialwissenschaften, Psychologie) und Medizin sowie die Elektronische Zeitschriftenbibliothek (EZB), ein kooperativer Service von 209 Bibliotheken zur Bereitstellung von elektronischen Zeitschriften, -die im Internet publiziert werden. "Wir planen überdies die Erweiterung um das Fach Germanistik, und wenn es soweit ist, wird die Stadt- und Universitätsbibliothek Frankfurt diesen Service bereitstellen", sagt Burblies."

Abstract

From 4 to 6 June 2003 the 2nd European Library Seminar / 3rd Gabriel Workshop was held at the Biblioteca Nacional in Lisbon, Portugal. 62 librarians and webmasters from 20 countries participated in the workshop, mainly Gabriel contacts but also quite a number of librarians from Portugal. Since its foundation in 1995 Gabriel, the world wide web service of the European national libraries, has established itself as the official network service of the Conference of European National Librarians (CENL) and has undergone a continuous development. The Gabriel website has been redesigned and restructured, and it was relaunched in summer 2002. At present, 41 libraries from 39 European countries are represented in Gabriel. Gabriel offers access to varied information sources and numerous online-catalogues and Services of the European national libraries. Gabriel is the only trans-European library service.

Abstract

A preliminary, purposive survey of definitions and current applications of facet analytical theory (FA) is used to develop a framework for the analysis of Websites. This set of guidelines may well serve to highlight commonalities and differences among FA applications an the Web. Rather than identifying FA as the terrain of a particular interest group, the goal is to explore current practices, uncover common misconceptions, extend understanding, and highlight developments that augment the traditional practice of FA and faceted classification (FC).

Abstract

Virtuelle Quellen zur Kunst-Erschließung und Recherchewar das Thema eines Workshops, der am 16. Oktober 2003 in der Sächsischen Landesbibliothek - Staats- und Universitätsbibliothek Dresden (SLUB) veranstaltet wurde. Anliegen war die Präsentation des DFG-geförderten Projektes ViFaArtVirtuelle Fachbibliothek Gegenwartskunst. Im Folgenden wird dieses Projekt näher vorgestellt. Schwerpunkt der Darstellung wird der hierbei entwickelte Katalog von Webseiten bzw. Internetquellen sein (Art-Guide). Die Auseinandersetzung mit Internetquellen und ihre Nutzung für die Informationsgewinnung ist auch für die Kunstwissenschaft zum aktuellen Thema geworden. Eine Hauptaufgabe des World Wide Web liegt neben dem schnellen und direkten Informationsaustausch in der Vermittlung von Information - einem Hauptanliegen wissenschaftlicher Bibliotheken überhaupt. Somit rückt die Problematik auch immer näher an den Aufgabenkreis von Bibliotheken heran. Es stellen sich Fragen wie: Welche Art von Informationen liegen im Web bereit, sind sie vertrauenswürdig, wie kann man sie nutzen und vor allem: wie sind sie zu finden? Seit 2000 wird an der SLUB eine Virtuelle Fachbibliothek zur Gegenwartskunst projektiert: ViFaArt. Das Projekt ist Partner von Vascoda, dem interdisziplinären Internetportal für wissenschaftliche Information in Deutschland. Unter http:// www.vascoda.de/sind Online- und Print-Informationen von derzeit über 20 Virtuellen Fachbibliotheken, 4 Informationsverbünden und der Elektronischen Zeitschriftenbibliothek (EZB) abrufbar. Anfang des nächsten Jahres wird auch ViFaArt den Katalog der Internetquellen (Art-Guide, vgl. unten) als Datenbank dort einbringen. Eine Metasuche über Vascoda wird dann also immer auch alle ArtGuide-Katalogisate berücksichtigen.

Abstract

While the Web has grown significantly in recent years, some portions of the Web remain largely underdeveloped, as shown in a lack of high-quality content and functionality. An example is the Arabic Web, in which a lack of well-structured Web directories limits users' ability to browse for Arabic resources. In this research, we proposed an approach to building Web directories for the underdeveloped Web and developed a proof-of-concept prototype called the Arabic Medical Web Directory (AMedDir) that supports browsing of over 5,000 Arabic medical Web sites and pages organized in a hierarchical structure. We conducted an experiment involving Arab participants and found that the AMedDir significantly outperformed two benchmark Arabic Web directories in terms of browsing effectiveness, efficiency, information quality, and user satisfaction. Participants expressed strong preference for the AMedDir and provided many positive comments. This research thus contributes to developing a useful Web directory for organizing the information in the Arabic medical domain and to a better understanding of how to support browsing on the underdeveloped Web.

Content

""Das Ehrenamt", schreibt Wikipedia, "bezeichnet ein öffentliches unbezahltes Amt, das durch soziale Anerkennung vergolten wird." Später heißt es weiter in eigener Sache: "Wikipedia wird zum größten Teil ehrenamtlich geleistet und stellt so eine neue Form von bürgerschaftlichem Engagement dar." Neu und unerwartet klingt das zunächst in der Tat: Das erfolgreichste Onlineprojekt seiner Art lebt nicht von den Millionen eines internationalen Konzerns, sondern dank der unentgeltlichen Arbeit seiner Nutzer. Steht das Internet doch in den Augen vieler vor allem für Kommerz und windige Geschäfte. Doch Wikipedia ist kein Einzelfall. Es gibt weitere Projekte im Internet, die in ihrer Qualität rein kommerziell kaum realisierbar sein dürften. Da ist etwa das "Open Directory" - nicht weniger als der Versuch, dem Internet ein Inhaltsverzeichnis zu geben. Ähnliche Kataloge professioneller Anbieter sind oft veraltet; zunehmend nehmen sie Adressen gegen Bezahlung vorrangig auf - was die Listen-Unabhängigkeit in Frage stellt. Beim "Open Directory" fließt kein Geld. Um die Einträge kümmern sich etwa 68.000 ehrenamtliche Editoren - eine Redaktionsstärke, die sich selbst finanzstarke Unternehmen kaum werden leisten wollen. Mehr als 400 Webseiten übernehmen den Katalog - unter anderem die bekannteste aller Web-Suchmaschinen in der Rubrik "Google Verzeichnis". Gegenseitiger Austausch und Hilfe - das macht entgegen mancher Wahrnehmung schon immer den Reiz des internets aus. Denn das Medium bringt Interessierte selbst für ungewöhnliche Vorlieben zusammen. Das geschieht oft abseits des bunten World Wide Web, etwa in Mail-Verteilerlisten oder den kaum bekannten Foren des Usenet. Sie leben von Debatten, Fragen und Antworten. Und sammeln erstaunliches Fachwissen - mal auf nationaler, mal auf internationaler Ebene. Google bietet einen Einblick in diese Welt unter groups.google.de. Freiwillig zusammen an einer gemeinsamen Sache arbeiten - das ist auch das Prinzip von Open-Source-Software, als deren prominenteste Vertreterin das Betriebssystem Linux gilt. Derartige Programme stehen unter bestimmten Bedingungen frei zur Verfügung. Den Aktiven ist die soziale Anerkennung sicher, von der Wikipedia spricht. Und manchmal nicht nur die. Hier und da wird aus dem Ehrenamt ein bezahlter Job - beispielsweise wenn es darum geht, Computersysteme zu betreuen, die mit der freien Software laufen."

Abstract

NOVAGate is a subject-based information gateway covering electronic resources in the agricultural, veterinary and related fields. The service, which opened in July 1998, is produced by the veterinary and agricultural libraries of the 5 Nordic countries - Denmark, Finland, Iceland, Norway and Sweden - which serve the NOVA University. The gateway covers Nordic and European resources as well as the resources of international organizations, but being planned is a network of subject gateways which will give access to a wide range of international quality resources within the agricultural, veterinary and related fields. The service uses the ROADS software

Abstract

Digital Libraries currently face the challenge of integrating many different types of research information (e.g. publications, primary data, expert's profiles, institutional profiles, project information etc.) according to their scientific users' needs. To date no general, integrated model for knowledge organization and retrieval in Digital Libraries exists. This causes the problem of structural and semantic heterogeneity due to the wide range of metadata standards, indexing vocabularies and indexing approaches used for different types of information. The research presented in this paper focuses on areas in which activities are being undertaken in the field of Digital Libraries in order to treat semantic interoperability problems. We present a model for the integrated retrieval of factual and textual data which combines multiple approaches to semantic interoperability und sets them into context. Embedded in the research cycle, traditional content indexing methods for publications meet the newer, but rarely used ontology-based approaches which seem to be better suited for representing complex information like the one contained in survey data. The benefits of our model are (1) easy re-use of available knowledge organisation systems and (2) reduced efforts for domain modelling with ontologies.

Abstract

Purpose - The paper aims to argue that digital library retrieval should be based on semantic representations and propose a semantic infrastructure for digital libraries. Design/methodology/approach - The approach taken is formal model based on subject representation for digital libraries. Findings - Search engines and search techniques have fallen short of user expectations as they do not give context based retrieval. Deploying semantic web technologies would lead to efficient and more precise representation of digital library content and hence better retrieval. Though digital libraries often have metadata of information resources which can be accessed through OAI-PMH, much remains to be accomplished in making digital libraries semantic web compliant. This paper presents a semantic infrastructure for digital libraries, that will go a long way in providing them and web based information services with products highly customised to users needs. Research limitations/implications - Here only a model for semantic infrastructure is proposed. This model is proposed after studying current user-centric, top-down models adopted in digital library service architectures. Originality/value - This paper gives a generic model for building semantic infrastructure for digital libraries. Faceted ontologies for digital libraries is just one approach. But the same may be adopted by groups working with different approaches in building ontologies to realise efficient retrieval in digital libraries.

Abstract

Reports a preliminary analysis of organizational schemes applied by academic libraries worldwide to arrange their electronic resources an their Web-based information gateways. The unsystematic sample consists of 41 academic libraries in 10 countries representing 4 languages, Chinese, English, German, and Spanish. The study reveals a widely accepted practice in applying 6 simplistic methods to organizing online information: by resource type, alphabetical by title, alphabetical by subject (mostly discipline and genre), by vendor/publisher, by broad classification, and random. In addition, it notes a marked difference between libraries in the English-speaking world and those in other countries in that the former present significantly more systematic characteristics.

Abstract

The Europeana Data Model (EDM) is a new approach towards structuring and representing data delivered to Europeana by the various contributing cultural heritage institutions. The model aims at greater expressivity and flexibility in comparison to the current Europeana Semantic Elements (ESE), which it is destined to replace. The design principles underlying the EDM are based on the core principles and best practices of the Semantic Web and Linked Data efforts to which Europeana wants to contribute. The model itself builds upon established standards like RDF(S), OAI-ORE, SKOS, and Dublin Core. It acts as a common top-level ontology which retains original data models and information perspectives while at the same time enabling interoperability. The paper elaborates on the aforementioned aspects and the design principles which drove the development of the EDM.

Abstract

Libraries have always been an inspiration for the standards and technologies developed by semantic web activities. However, except for the Dublin Core specification, semantic web and social networking technologies have not been widely adopted and further developed by major digital library initiatives and projects. Yet semantic technologies offer a new level of flexibility, interoperability, and relationships for digital repositories. Kruk and McDaniel present semantic web-related aspects of current digital library activities, and introduce their functionality; they show examples ranging from general architectural descriptions to detailed usages of specific ontologies, and thus stimulate the awareness of researchers, engineers, and potential users of those technologies. Their presentation is completed by chapters on existing prototype systems such as JeromeDL, BRICKS, and Greenstone, as well as a look into the possible future of semantic digital libraries. This book is aimed at researchers and graduate students in areas like digital libraries, the semantic web, social networks, and information retrieval. This audience will benefit from detailed descriptions of both today's possibilities and also the shortcomings of applying semantic web technologies to large digital repositories of often unstructured data.

Abstract

The concept for the German Digital Libraries Program is imbedded in the Information Infrastructure Program of the German Federal Government for the years 1996-2000 which has been explicated in the Program Paper entitled "Information as Raw Material for Innovation".3 The Program Paper was published 1996 by the Federal Ministry for Education, Research, and Technology. The actual grants program "Global Info" was initiated by the Information and Communication Commission of the Joint Learned Societies to further technological advancement in enabling all researchers in Germany direct access to literature, research results, and other relevant information. This Commission was founded by four of the learned societies in 1995, and it has sponsored a series of workshops to increase awareness of leading edge technology and innovations in accessing electronic information sources. Now, nine of the leading research-level learned societies -- often those with umbrella responsibilities for other learned societies in their field -- are members of the Information and Communication Commission and represent the mathematicians, physicists, computer scientists, chemists, educational researchers, sociologists, psychologists, biologists and information technologists in the German Association of Engineers. (The German professional librarian societies are not members, as such, of this Commission, but are represented through delegates from libraries in the learned societies and in the future, hopefully, also by the German Association of Documentalists or through the cooperation between the documentalist and librarian professional societies.) The Federal Ministry earmarked 60 Million German Marks for projects within the framework of the German Digital Libraries Program in two phases over the next six years. The scope for the German Digital Libraries Program was announced in a press release in April 1997,4 and the first call for preliminary projects and expressions of interest in participation ended in July 1997. The Consortium members were suggested by the Information and Communication Commission of the Learned Societies (IuK Kommission), by key scientific research funding agencies in the German government, and by the publishers themselves. The first official meeting of the participants took place on December 1, 1997, at the Deutsche Bibliothek, located in the renowned center of German book trade, Frankfurt, thus documenting the active role and participation of libraries and publishers. In contrast to the Digital Libraries Project of the National Science Foundation in the United States, the German Digital Libraries project is based on furthering cooperation with universities, scientific publishing houses (including various international publishers), book dealers, and special subject information centers, as well as academic and research libraries. The goals of the German Digital Libraries Project are to achieve: 1) efficient access to world wide information; 2) directly from the scientist's desktop; 3) while providing the organization for and stimulating fundamental structural changes in the information and communication process of the scientific community.
