- Abstract
- In diesem Kapitel werden Anwendungsgebiete und Ansätze für die semantische Beschreibung von Web Services behandelt. Bestehende Web Service Technologien leisten einen entscheidenden Beitrag zur Entwicklung verteilter Anwendungen dadurch, dass weithin akzeptierte Standards vorliegen, die die Kommunikation zwischen Anwendungen bestimmen und womit deren Kombination zu komplexeren Einheiten ermöglicht wird. Automatisierte Mechanismen zum Auffinden geeigneter Web Services und deren Komposition dagegen werden von bestehenden Technologien in vergleichsweise geringem Maß unterstützt. Ähnlich wie bei der Annotation statischer Daten im "Semantic Web" setzen Forschung und Industrie große Hoffnungen in die semantische Beschreibung von Web Services zur weitgehenden Automatisierung dieser Aufgaben.

- 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
- Reports on the current state of reference services supplied by the WWW and describes: the main features of WWW based reference services; several models of handling requests; and the impact of these services on traditional reference services. Based upon anecdotal information, concludes that, to date, Web based reference services have had little impact upon traditional reference services

- Abstract
- Wer Informationen sucht, wird im Internet meist irgendwie fündig. Dennoch erweist sich eine zielgerichtete »intelligente« Suche nach konkreten Informationen und ihre Verknüpfung trotz der immer raffinierteren Suchmechanismen von Google & Co. als schwierig. Hoffnung verbreitet derzeit die Idee vom semantischen Web. Das »einzige Bedeutungsnetz von allem und jedem« (WWW-Erfinder Tim Bernes-Lee) wird als universelle Weiterentwicklung des World Wide Web gehandelt. Das Bundesministerium für Bildung und Forschung will deshalb bis 2006 insgesamt 13,7 Millionen Euro in die Förderung dieser Technologie stecken. Bis dahin wollen die Projektpartner eine erste Anwendung der neuen Technologie präsentieren: Das »Smart Web« soll Service-Informationen zu den einzelnen Spielen der Fußballweltmeisterschaft liefern und auch Reiseanfragen beantworten können. Im semantischen Web wird allen möglichen Dingen - also beispielsweise Texten, Bildern, Musik und Videos - eine Bedeutung zugewiesen. Diese Angaben werden als Metadaten bezeichnet, als Informationen über Informationen. Der Vorteil: Das durch die Verknüpfung dieser Daten entstehende Netz aus Bedeutungen ist für Software »lesbar«, so dass nicht nur die »Dinge« sondern auch ihre Zusammenhänge untereinander von Algorithmen ausgewertet und verstanden werden können. Das semantische Web überführt das WWW von einem »Netz von Dokumenten« in ein »Netz von Informationen«. So bekommen fünfstellige Zahlen z.B. die Zuweisung »Postleitzahl«, wenn sie eine solche sind. Und das Wort »Kohl« würde ggf. in die Kategorie »Gemüse« fallen. Suchmaschinen würden so Informationen »verstehen« und wie das menschliche Gehirn assoziative Querverbindungen zwischen unterschiedlichen Dokumenten herstellen. Entsprechend könnten sie eine Frage wie: »Wer war 2004 deutscher Bundeskanzler?« mit »Gerhard Schröder« beantworten und Links mit weiteren Informationen zur Person des Bundeskanzlers (und nicht einer anderen Person gleichen Namens) angeben. Das Internet würde so zu dem globalen Gehirn, über das schon Visionäre wie H.G. Wells philosophierten, und wäre mehr als nur die Summe seiner Daten.

- Abstract
- While many catalogers are using the Web to find the information they need to perform authority work quickly and accurately, the full potential of the Web to assist catalogers in name authority work has yet to be realized. The ever-growing nature of the Web means that available information for creating personal name, corporate name, and other types of headings will increase. In this article, we examine ways in which simple and effective Web searching can save catalogers time and money in the process of authority work. In addition, questions involving evaluating authority information found on the Web are explored.

- Abstract
- In Zeiten zunehmend wissensintensiver Berufsbilder besteht eine große Herausforderung heutiger Unternehmen darin, die zur Unterstützung organisatorischen Handelns erforderliche Information effizient und effektiv zur Verfügung zu stellen. Eine Grundlage für die Entwicklung einer adäquaten Informationsumgebung legt dabei das umfassende Verständnis des Kontexts und Verhaltens von Mitarbeitern im Umgang mit Information. Beides unterliegt jedoch einem steten Wandel und stellt hohe Anforderungen an die Flexibilität von Arbeitsplatzkonzepten und der Gestaltung von Informationsumgebungen. In diesem Artikel wird daher die aktuelle Bedeutung und Entwicklung informationswissenschaftlicher Ansätze zur Modellierung von Informationssuchverhalten, deren Methoden, sowie zentrale Konzepte und Erkenntnisse vorgestellt. Anschließend wird die Bedeutung dieser Modelle für den Arbeitsplatz-Kontext in Zeiten zunehmend wissensintensiver Tätigkeiten untersucht. Anhand der Wandlung des primär informativ genutzten Internet zu einem partizipativen Social Web wird daraufhin erörtert, welche neuen Entwicklungen es in der Erforschung des Nutzerkontexts zu berücksichtigen gilt. Die beispielhafte Betrachtung aktueller Forschungsergebnisse auf diesem Gebiet mündet in einer Diskussion weiteren Forschungsbedarfs.

- Abstract
- Provides a framework for analysing the utility, usability and likeability of net and web services and illustrates its application to significant aspects of supporting scholarly communities. The utility of the net and web are measured in terms of the growth of usage and the different services involved are distinguished in terms of their specific utilities. A layered protocol model is used to model discourse through the net and is extended to encompass interaction in communities. An operational criterion for distinguishing different communities is defined in terms of the types of awareness that resource providers and user have of one another. Develops a temporal model of discourse that enables the spectrum of services ranging from real-time discourse to long-term publication to be analyzed in a unified framework. The dimensions of awareness and time are used to characterise and compare the full range of net services and model their unification through the next generation of web browsers

- Abstract
- Mit über 1100 Delegierten und 85 Ausstellern stellte die zwölfte Information Online auch 2005 wieder die im Raum Asien und Pazifik größte und renommierteste regionale Fachmesse für den Informationsbereich dar. Alle zwei Jahre veranstaltet der australische Informationsberufe-Verband ALIA in Sydney die Tagung mit Fachreferenten aus Australien, Asien, Europa und USA. An drei bis fünf Tagen kommen hier Bibliothekare und Informationsspezialisten aus Australien und Neuseeland, Indien, Malaysien, Amerika, und Europa zusammen, um sich anhand von Vorträgen, Workshops, einer Fachausstellung und reichlich Gelegenheiten für informelles Networking einen Überblick über den sich rasant entwickelnden Markt des elektronischen Informationsmanagement und der Informationsversorgung zu verschaffen. 60 Referenten und neun Hauptredner (Angela Abell, Kate Andrews, Liesle Capper, Peter Crowe, Prof. Brian Fitzgerald, David Hawking, Mary Lee Kennedy, Hemant Manohar, Joan Frye Williams) lieferten Forschungsergebnisse, Fallstudien, Fortschrifttsberichte und programmatische Thesen aus den Themenbereichen Informationsarchitektur, Online Archive, Content Management Systeme, Urheberrecht und WWW, Web Services für Bibliotheken und Informationsstellen, Benutzungsschemata für Web-Technologien, Schnittstellen, Datenpool, Bibliotheksautomation, Referenzservice online, Metadaten für Informationssysteme und für Organisationen, Wissenschaftliches Publizieren, Open Access, Knowledge Management und intellektuelles Kapital, Benutzerpsychologie, Online lernen, Berufsbild Informationsspezialist. Ein Drittel der Beiträge beschäftigte sich mit Fragen rund um Information beziehungsweise Knowledge Discovery Search, Search und nochmals Search. Dreht sich angesichts der kommerziellen Erfolge von Google und Konsorten denn alles nur noch um die Websuche?

- Abstract
- Das Werk behandelt die aktuellen Entwicklungen zur inhaltlichen Erschließung von Informationsquellen im Internet. Topic Maps, semantische Modelle vernetzter Informationsressourcen unter Verwendung von XML bzw. HyTime, bieten alle notwendigen Modellierungskonstrukte, um Dokumente im Internet zu klassifizieren und ein assoziatives, semantisches Netzwerk über diese zu legen. Neben Einführungen in XML, XLink, XPointer sowie HyTime wird anhand von Einsatzszenarien gezeigt, wie diese neuartige Technologie für Content Management und Information Retrieval im Internet funktioniert. Der Entwurf einer Abfragesprache wird ebenso skizziert wie der Prototyp einer intelligenten Suchmaschine. Das Buch zeigt, wie Topic Maps den Weg zu semantisch gesteuerten Suchprozessen im Internet weisen.

- Abstract
- Mit der Einführung einer europarechtlich flankierten Geodateninfrastruktur gewinnen geobasierte Daten und Anwendungen zunehmend an Bedeutung. Auch die öffentliche Verwaltung will hieran partizipieren und ihre raumbezogenen Daten der Öffentlichkeit zur Verfügung stellen. Damit wird eine datenschutzrechtlich bisher vor allem am Beispiel des Google-Dienstes Street-View diskutierte Frage akut, ob oder wann es sich bei solchen Daten um personenbezogene Daten nach dem Datenschutzrecht handelt. Der Beitrag tritt dem Vorschlag entgegen, solche Daten aus dem Anwendungsbereich des Datenschutzrechtes herauszuinterpretieren, sondern fordert den Gesetzgeber auf eine bereichsspezifische Befugnisnorm mit korrespondierenden Schutzregelungen zu erlassen. Hierfür werden Rahmenbedingungen skizziert und eine Formulierung am Beispiel des Gesetzgebungsverfahrens in Mecklenburg-Vorpommern vorgeschlagen.
