"Das rasant wachsende Wissen muss gut verwaltet werden, um es zu nutzen. Dies erfordert intelligente Wissensmanagementsysteme, wie sie Andreas Rauber von der Technischen Uni Wien über digitale Bibliotheken konzipiert hat. Seine "Wissenslandkarte" erlaubt es, große Datenmengen übersichtlich darzustellen, Wissen rasch auffindbar und damit optimal einsetzbar zu machen. Dafür erhielt er nun den Cor Baayen Award 2002 für aussichtsreiche Nachwuchsforscher im Bereich der Informationstechnologie vom European Research Consortium for Informatics and Mathematics. Rauber entwickelte eine Bibliothek, die auf einer sich selbst organisierenden Landkarte basiert: Einer geographischen Landkarte gleich, ist themenverwandtes Wissen in Form eines Clusters abgebildet, quasi als städtischer Ballungsraum. Damit verbundene Inhalte sind räumlich gesehen in kurzer Distanz dazu abgebildet, vergleichbar den Randgebieten des Ballungsraumes. So ist auf einen Blick ersichtlich, wo bestimmte Themenkomplexe und damit verbundene Inhalte in der Bibliothek abgelegt sind. Die Wissenslandkarte bedient sich der Forschungen zu neuronalen Netzen. Durch ein Verfahren erlernt die "Self-Organizing-Map" (SOM) die Inhalte der einzelnen Dokumente und schafft es, mit zunehmender Datenmenge selbst eine Struktur des vorhandenen Wissens zu erstellen. Dieses Verfahren ist sprachunabhängig und daher weltweit einsetzbar."

Abstract

Inhaltliche Daten sind im Unterschied zu Messdaten, Zahlen, Analogsignalen und anderen Informationen solche Daten, die sich auch sprachlich interpretieren lassen. Sie transportieren Inhalte, die sich benennen lassen. Zu inhaltlichen Daten gehören z. B. Auftragsdaten, Werbetexte, Produktbezeichnungen und Patentklassifikationen. Die meisten Daten, die im Internet kommuniziert werden, sind inhaltliche Daten. Man kann inhaltliche Daten in vier Klassen einordnen: * Wissensdaten - formatierte Daten (Fakten u. a. Daten in strukturierter Form), - nichtformatierte Daten (vorwiegend Texte); * Zugriffsdaten - Benennungsdaten (Wortschatz, Terminologie, Themen u. a.), - Begriffsdaten (Ordnungs- und Bedeutungsstrukturen). In der Wissensorganisation geht es hauptsächlich darum, die unüberschaubare Fülle des Wissens zu ordnen und wiederauffindbar zu machen. Daher befasst sich das Fach nicht nur mit dem Wissen selbst, selbst sondern auch mit den Mitteln, die dazu verwendet werden, das Wissen zu ordnen und auffindbar zu machen

Abstract

Europeana ist eine Initiative der Europäischen Kommission, die 2005 den Aufbau einer "Europäischen digitalen Bibliothek" als Teil ihrer i2010 Agenda ankündigte. Europeana soll ein gemeinsamer multilingualer Zugangspunkt zu Europas digitalem Kulturerbe und gleichzeitig mehr als "nur" eine digitale Bibliothek werden: eine offene Schnittstelle (API) für Wissenschaftsanwendungen, die ein Netzwerk von Objektsurrogaren darstellt, die semantikbasiertes Objektretrieval und - verwendung ermöglichen. Einerseits ist die semantische Kontextualisierung der digitalen Objekte eine unabdingbare Voraussetzung für effektives Information Retrieval, da aufgrund der Beschaffenheit der Öbjekte (bildlich, multimedial) deskriptive Metadaten meist nicht ausreichen, auf der anderen Seite bildet sie die Grundlage für neues Wissen. Kern geisteswissenschaftlicher Arbeit ist immer schon die Reaggregation und Interpretation kultureller Artefakte gewesen und Europeana ermöglicht nun mit (teil-)automatisierbaren, semantikbasierten Öperationen über große kulturelle Quellcorpora völlig neue Perspektiven für die digital humanities. Folglich hat Europeans das Potenzial eine Schlüsselressource der Geistes- und Kulturwissenschaften und damit Teil deren zukünftiger digitaler Arbeitsumgebungen zu werden.
