Footnote

Mehrere Beiträge befassen sich mit dem Problem der Relevanz. Erica Cosijn und Theo Bothma (Pretoria) argumentieren, dass für das Benutzerverhalten neben der thematischen Relevanz auch verschiedene andere Relevanzdimensionen eine Rolle spielen und schlagen auf der Basis eines (abermals auf Ingwersen zurückgehenden) erweiterten Relevanzmodells vor, dass IR-Systeme die Möglichkeit zur Abgabe auch kognitiver, situativer und sozio-kognitiver Relevanzurteile bieten sollten. Elaine Toms et al. (Kanada) berichten von einer Studie, in der versucht wurde, die schon vor 30 Jahren von Tefko Saracevic3 erstellten fünf Relevanzdimensionen (kognitiv, motivational, situativ, thematisch und algorithmisch) zu operationalisieren und anhand von Recherchen mit einer Web-Suchmaschine zu untersuchen. Die Ergebnisse zeigten, dass sich diese fünf Dimensionen in drei Typen vereinen lassen, die Benutzer, System und Aufgabe repräsentieren. Von einer völlig anderen Seite nähern sich Olof Sundin und Jenny Johannison (Boras, Schweden) der Relevanzthematik, indem sie einen kommunikationsorientierten, neo-pragmatistischen Ansatz (nach Richard Rorty) wählen, um Informationssuche und Relevanz zu analysieren, und dabei auch auf das Werk von Michel Foucault zurückgreifen. Weitere interessante Artikel befassen sich mit Bradford's Law of Scattering (Hjørland & Nicolaisen), Information Sharing and Timing (Widén-Wulff & Davenport), Annotations as Context for Searching Documents (Agosti & Ferro), sowie dem Nutzen von neuen Informationsquellen wie Web Links, Newsgroups und Blogs für die sozial- und informationswissenschaftliche Forschung (Thelwall & Wouters). In Summe liegt hier ein interessantes und anspruchsvolles Buch vor - inhaltlich natürlich nicht gerade einheitlich und geschlossen, doch dies darf man bei einem Konferenzband ohnedies nicht erwarten. Manche der abgedruckten Beiträge sind sicher nicht einfach zu lesen, lohnen aber die Mühe. Auch für Praktiker aus Bibliothek und Information ist einiges dabei, sofern sie sich für die wissenschaftliche Basis ihrer Tätigkeit interessieren. Fachlich einschlägige Spezial- und grössere Allgemeinbibliotheken sollten das Werk daher unbedingt führen.

Abstract

Dieser Aufsatz beschreibt die Entwicklung der Suchmaschine BASE (Bielefeld Academic Search Engine) seit 2005. In dieser Zeit wurde der Index um ein Vielfaches ausgebaut und auch die Nutzungszahlen stiegen deutlich. Der Schwerpunkt liegt auf der Indexierung von Dokumentenservern, die ihre Daten über das "Protocol for Metadata Harvesting" (OAI-PMH) bereitstellen. Im Gegensatz zu speziellen OAI-Suchmaschine wie OAIster verfügt BASE jedoch über weitergehende Suchmöglichkeiten und indexiert auch wissenschaftliche Webseiten mit Hilfe eines integrierten Web-Crawlers und andere Quellen, wie zum Beispiel den Bibliothekskatalog der Universitätsbibliothek Bielefeld. BASE kommt darüber hinaus als Suchsystem auch in anderen Bereichen, zum Beispiel im Bielefeld eScholarship Repository, als Suchmaschine der Universität Bielefeld und im EU-Projekt DRIVER via Schnittstellen zum BASE-Index zum Einsatz.

"Die TI B ist die weltweit erste Registrierungsagentur fürwissenschaftliche Primärdaten. In Zusammenarbeit mit dem Weltklimadatenzentrum am Max-Planck-Institut für Meteorologie (Hamburg), dem Geoforschungszentrum (Potsdam), dem Weltdatenzentrum MARE am Alfred-Wegener-Institut (Bremerhaven) und der Universität Bremen sowie dem Forschungszentrum L3S (Hannover) wurde das DFG-finanzierte Projekt Codata »Publikation und Zitierfähigkeit wissenschaftlicher Primärdaten« 2004 mit dem Ziel aus der Taufe gehoben, den Zugang zu wissenschaftlichen Primärdaten zu verbessern. In Codata wurde ein Modell entwickelt, welches erstmals den Nachweis und die Zitierfähigkeit von Primärdaten ermöglicht und eine dauerhafte Adressierbarkeit gewährleistet. Nutznießer dieses neuen Verfahrens sind in erster Linie Wissenschaftler, die eigene Primärdaten erheben, sowie diejenigen, die diese Daten für eigene, weiterführende Arbeiten nutzen wollen. Der klassische Weg der Veröffentlichung von Forschungsergebnissen führt über Aufsätze in Fachzeitschriften, welche im »Citation Index« aufgelistet werden. Anhand dessen findet eine Leistungsbewertung der Wissenschaftler statt. Veröffentlichungen von Primärdaten, die für Wissenschaftler zusätzliche Arbeit hinsichtlich Aufbereitung, Dokumentation und Qualitätssicherung bedeuten, wurden bisher nicht in die Bewertung mit aufgenommen. Wissenschaftliches Fehlverhalten in der Vergangenheit führte zu den so genannten »Regeln zur guten wissenschaftlichen Praxis«, empfohlen von der Deutschen Forschungsgemeinschaft (DFG). Diese Regeln beinhalten Richtlinien hinsichtlich Datenzugang und Langzeitarchivierung. Daten, die allgemein verfügbaren Publikationen zugrunde liegen, sollen auch für andere überprüfbar und ihre Erhebung nachvollziehbar sein. Gleichzeitig trägt Codata der seit langem formulierten Forderung nach freiem Online-Zugang zu jeder Art wissenschaftlicher Information Rechnung und unterstützt damit die Open Access-Initiative. Das neue Konzept der Zitierfähigkeit von Primärdaten verbindet wissenschaftliche Langzeitarchive mit traditionellen Bibliothekskatalogen, um wissenschaftliche Daten nachweisbar und zusammen mit alternativen Informationsressourcen suchbarzu machen. Die TIB speichert die Informationen zu den Primärdaten ab und versieht die Daten mit einer eindeutigen Identifikationsnummer, einem Digital Object Identifier (DOI). Nun ist jeder Wissenschaftler in der Lage, die Daten in seiner Arbeit mit der DOI als einzigartiger Kennung zu zitieren. Zitiert werden Autor, Jahr der Veröffentlichung, Titel sowie der DOI als einzigartige Zugangskennung. Wissenschaftliche Primärdaten bekommen dadurch eine eigene Identität und können als unabhängige, eigenständige Informationseinheit genutzt werden. Inzwischen wurden bereits 220000 Datensätze in der TIB registriert. Vierzig Datensätze sind mittlerweile über Tiborder, das Bestell- und Liefersystem der TIB, nachweisbar und zugänglich. Bis Ende des Jahres sollen rund 1,5 Millionen Datensätze von der TIB registriert sein. Zurzeit sind vornehmlich Messdaten aus dem Gebiet der Geowissenschaften registriert, ab 2006 wird die Registrierung von Primärdaten auch auf andere Sammelgebiete ausgeweitet."

Abstract

Google hat mit "Hummingbird" einen neuen Suchalgorithmus entwickelt und bereits eingeführt. Dabei handelt es sich laut Google um eine der größten Veränderungen der Suchmaschine, die rund 90 Prozent aller Suchanfragen betrifft. Im Rahmen einer kleinen Veranstaltung zum 15. Geburtstag der Suchmaschine hat Google in die Garage geladen, in der das Unternehmen gegründet wurde. Dabei enthüllte Google eine der bisher größten Veränderungen an der Suchmaschine: Ohne dass Nutzer etwas davon mitbekamen, hat Google vor rund einem Monat seinen Suchalgorithmus ausgetauscht. Der neue Suchalgorithmus mit Codenamen "Hummingbird" soll es Google ermöglichen, Suchanfragen und Beziehungen zwischen Dingen besser zu verstehen. Das soll die Suchmaschine in die Lage versetzen, komplexere Suchanfragen zu verarbeiten, die von Nutzern immer häufiger gestellt werden - auch, weil immer mehr Nutzer Google auf dem Smartphone per Spracheingabe nutzen. Früher versuchte Google lediglich, die Schlüsselwörter in einer Suchanfrage in Webseiten wiederzufinden. Doch seit geraumer Zeit arbeitet Google daran, die Suchanfragen besser zu verstehen, um bessere Suchergebnisse anzuzeigen.
