Abstract

Mit Information Retrieval (IR) sind in Forschung und Entwicklung in unterschiedlicher Breite und aus verschiedenen Perspektiven mehrere Disziplinen befasst. Die verschiedenen Ausrichtungen sind wichtig, da nur in ihrer Verknüpfung eine Gesamtschau des IR vermittelt werden kann. Die Informatik verfolgt einen stärker systemgetriebenen, technologischen Ansatz des IR und stellt Algorithmen und Implementationen in den Vordergrund, während für die Informationswissenschaft die Benutzer*innen in ihren vielschichtigen Kontexten den Schwerpunkt bilden. Deren Eigenschaften (fachlicher Hintergrund, Domänenzugehörigkeit, Expertise etc.) und Zielsetzungen, die durch das IR verfolgt werden, spielen im Interaktionsprozess zwischen Mensch und System eine zentrale Rolle. Auch wird intensiv der Frage nachgegangen, wie sich Benutzer*innen in diesen Prozessen verhalten und aus welchen Gründen sie verschiedene Systeme in Anspruch nehmen. Da ein Großteil des heutigen Wissens nach wie vor in Texten repräsentiert ist, ist eine weitere Disziplin - nämlich die Computerlinguistik/Sprachtechnologie für das IR von Bedeutung. Zusätzlich kommen aber auch visuelle und auditive Wissensobjekte immer stärker zum Tragen und werden aufgrund ihrer anwachsenden Menge immer wichtiger für das IR. Ein neues Fachgebiet ist die Data Science, die auf altbekannten Konzepten aus Statistik und Wahrscheinlichkeitsrechnung aufsetzt, auf den Daten operiert und auch traditionelles IR-Wissen für die Zusammenführung von strukturierten Fakten und unstrukturierten Texten nutzt. Hier soll die informationswissenschaftliche Perspektive im Vordergrund stehen.
