- Abstract
- Eine ganze Anzahl von Bibliotheken in Europa befaßt sich mit der Entwicklung von Internet Subject Gateways - einer Serviceleistung, die den Nutzern helfen soll, qualitativ hochwertige Internetquellen zu finden. Subject Gateways wie SOSIG (The Social Science Information Gateway) sind bereits seit einigen Jahren im Internet verfügbar und stellen eine Alternative zu Internet-Suchmaschinen wie AltaVista und Verzeichnissen wie Yahoo dar. Bezeichnenderweise stützen sich Subject Gateways auf die Fertigkeiten, Verfahrensweisen und Standards der internationalen Bibliothekswelt und wenden diese auf Informationen aus dem Internet an. Dieses Referat will daher betonen, daß Bibliothekare/innen idealerweise eine vorherrschende Rolle im Aufbau von Suchservices für Internetquellen spielen und daß Information Gateways eine Möglichkeit dafür darstellen. Es wird einige der Subject Gateway-Initiativen in Europa umreißen und die Werkzeuge und Technologien beschreiben, die vom Projekt DESIRE entwickelt wurden, um die Entwicklung neuer Gateways in anderen Ländern zu unterstützen. Es wird auch erörtert, wie IMesh, eine Gruppe für Gateways aus der ganzen Welt eine internationale Strategie für Gateways anstrebt und versucht, Standards zur Umsetzung dieses Projekts zu entwickeln

- How should Google be regulated? We should limit the amount of information that is being collected. In particular we should look at information that is being collected across sites. It should not be legal to combine data from multiple sites and services. The fact that these sites and services are using the same underlying technology does not change the fact that the user's dealings is with a site at a time and each site should not have the right to share the data with others. I believe this the cornerstone of laws in many countries today, but these laws need to be enforced. Data about us is ours alone and it should not be possible to sell it. We should also limit the ability to target users individually. In the past, ads on sites were ads on sites. You might know what kind of users visited a site and you would place tech ads on tech sites and fashion ads on fashion sites. Now the ads follow you individually. That should be made illegal as it uses data collected from multiple sources and invades our privacy. I also believe there should be regulation as to how location data is used and any information related to our mobile devices. In addition, regulators need to be vigilant as to how companies that have monopoly power use their power. That kind of goes without saying. Companies with monopoly powers should not be able to use those powers when competing in an open market or using their monopoly services to limit competition."

- Abstract
- Im Rahmen des klassischen Information Retrieval wurden verschiedene Verfahren für das Ranking sowie die Suche in einer homogenen strukturlosen Dokumentenmenge entwickelt. Die Erfolge der Suchmaschine Google haben gezeigt dass die Suche in einer zwar inhomogenen aber zusammenhängenden Dokumentenmenge wie dem Internet unter Berücksichtigung der Dokumentenverbindungen (Links) sehr effektiv sein kann. Unter den von der Suchmaschine Google realisierten Konzepten ist ein Verfahren zum Ranking von Suchergebnissen (PageRank), das in diesem Artikel kurz erklärt wird. Darüber hinaus wird auf die Konzepte eines Systems namens CiteSeer eingegangen, welches automatisch bibliographische Angaben indexiert (engl. Autonomous Citation Indexing, ACI). Letzteres erzeugt aus einer Menge von nicht vernetzten wissenschaftlichen Dokumenten eine zusammenhängende Dokumentenmenge und ermöglicht den Einsatz von Banking-Verfahren, die auf den von Google genutzten Verfahren basieren.

- 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
- Kleinberg's HITS (Hyperlink-Induced Topic Search) algorithm (Kleinberg 1999), which was originally developed in a Web context, tries to infer the authoritativeness of a Web page in relation to a specific query using the structure of a subgraph of the Web graph, which is obtained considering this specific query. Recent applications of this algorithm in contexts far removed from that of Web searching (Bacchin, Ferro and Melucci 2002, Ng et al. 2001) inspired us to study the algorithm in the abstract, independently of its particular applications, trying to mathematically illuminate its behaviour. In the present paper we detail this theoretical analysis. The original work starts from the definition of a revised and more general version of the algorithm, which includes the classic one as a particular case. We perform an analysis of the structure of two particular matrices, essential to studying the behaviour of the algorithm, and we prove the convergence of the algorithm in the most general case, finding the analytic expression of the vectors to which it converges. Then we study the symmetry of the algorithm and prove the equivalence between the existence of symmetry and the independence from the order of execution of some basic operations on initial vectors. Finally, we expound some interesting consequences of our theoretical results.

- "Es gibt Daten, Informationen und Fakten. Wenn man mir eine Zahlenreihe vorsetzt, dann handelt es sich um Daten: unterscheidbare Einheiten, im Fachjargon: Items. Wenn man mir sagt, dass diese Items stündliche Temperaturangaben der Aare im Berner Marzilibad bedeuten, dann verfüge ich über Information - über interpretierte Daten. Wenn man mir sagt, dies seien die gemessenen Aaretemperaturen am 22. August 2016 im Marzili, dann ist das ein Faktum: empirisch geprüfte interpretierte Daten. Dieser Dreischritt - Unterscheiden, Interpretieren, Prüfen - bildet quasi das Bindemittel des Faktischen, «the matter of fact». Wir alle führen den Dreischritt ständig aus und gelangen so zu einem relativ verlässlichen Wissen und Urteilsvermögen betreffend die Dinge des Alltags. Aber wie schon die Kurzcharakterisierung durchblicken lässt, bilden Fakten nicht den Felsengrund der Realität. Sie sind kritikanfällig, sowohl von der Interpretation wie auch von der Prüfung her gesehen. Um bei unserem Beispiel zu bleiben: Es kann durchaus sein, dass man uns zwei unterschiedliche «faktische» Temperaturverläufe der Aare am 22. August 2016 vorsetzt.

- Empört zogen US-Autoren und -Verlage vor Gericht und handelten im Herbst einen Vergleich aus, den das Gericht noch genehmigen muss. Er sieht vor, dass Google die Verfahrenskosten trägt, jedem Autor eines ungenehmigt digitalisierten Buches 60 US-Dollar zahlt (insgesamt 45 Millionen US-Dollar) sowie 34,5 Millionen US-Dollar für die Gründung eines digitalen, von Google unabhängigen Buchregisters bereitstellt. Das Register soll die Einnahmen verteilen (37 Prozent an Google, 63 Prozent an die Rechteinhaber), die Google erwirtschaftet aus dem kostenpflichtigen Zugang zu Büchern oder ihrem Download (als Ebook oder Book on Demand), aus der Werbung sowie aus Online-Abonnements für Institutionen und Bibliotheken. Und natürlich dürfen die Scan-Maschinen weiter laufen. Die Konsequenzen des Vergleichs lassen tief durchatmen. Google erhält, warnt Robert Darnton in "The New York Review of Books", praktisch ein Digitalisierungsmonopol für die USA. Mehr noch: Die millionenfache Verletzung des Urheberrechts wird pragmatisch durchgewunken. Die Verlage erfreut nämlich, dass Google ein neues Geschäftsfeld erschlossen hat: all die vergriffenen Bücher, deren Nachdruck sie für nicht lohnend halten. Die Suchmaschinenfirma geht ihrerseits vom Prinzip der Finanzierung durch Werbung ab: Google wird auf einen Schlag weltgrößter Verleger und weltgrößter Buchhändler. Die Buchsuche wandelt sich zum Online-Buch(inhalte)verkauf.
