Abstract

Examines the effectiveness of automated indexing and presents the results of a study of information retrieval from a segment (40.000 items) of the ULB Düsseldorf database. The segment was selected randomly and all the documents included were indexed automatically. The search topics included 50 subject areas ranging from economic growth to alternative energy sources. While there were 876 relevant documents in the database segment for each of the 50 search topics, the recall ranged from 1 to 244 references, with the average being 17.52 documents per topic. Therefore it seems that, in the immediate future, automatic indexing should be used in combination with intellectual indexing

Abstract

Unter Indexierung versteht man die Zuordnung von inhaltskennzeichnenden Ausdrücken (Indextermen, Indexaten, Erschließungsmerkmalen) zu Dokumenten. Über die zugeteilten Indexterme soll ein gezieltes Auffinden der Dokumente ermöglicht werden. Indexterme können inhaltsbeschreibende Merkmale wie Notationen, Deskriptoren, kontrollierte oder freie Schlagwörter sein; es kann sich auch um reine Stichwörter handeln, die aus dem Text des Dokuments gewonnen werden. Eine Indexierung kann intellektuell, computerunterstützt oder automatisch erfolgen. Computerunterstützte Indexierungsverfahren kombinieren die intellektuelle Indexierung mit automatischen Vorarbeiten. Bei der automatischen Indexierung werden die Indexterme automatisch aus dem Dokumenttext ermittelt und dem Dokument zugeordnet. Automatische Indexierung bedient sich für die Verarbeitung der Zeichenketten im Dokument linguistischer und statistischer Verfahren.

Abstract

Automatic content indexing is one of the innovations that are increasingly changing the way libraries work. In theory, it promises a cataloguing service that would hardly be possible with humans in terms of speed, quantity and maybe quality. The German National Library (DNB) has also recognised this potential and is increasingly relying on the automatic indexing of their catalogue content. The DNB took a major step in this direction in 2017, which was announced in two papers. The announcement was rather restrained, but the content of the papers is all the more explosive for the library community: Since September 2017, the DNB has discontinued the intellectual indexing of series Band H and has switched to an automatic process for these series. The subject indexing of online publications (series O) has been purely automatical since 2010; from September 2017, monographs and periodicals published outside the publishing industry and university publications will no longer be indexed by people. This raises the question: What is the quality of the automatic indexing compared to the manual work or in other words to which degree can the automatic indexing replace people without a signi cant drop in regards to quality?

Abstract

We provide a model for the reception of knowledge from externalized information sources. The model is based on a cognitive understanding of information processing and draws up ideas of an exchange of information in communication processes. Karl Popper's three-world theory with its orientation on falsifiable scientific knowledge is extended by John Searle's concept of collective intentionality. This allows a consistent description of externalization and reception of knowledge including scientific knowledge as well as everyday knowledge.

Abstract

Information literacy and autonomy have become key values for the image of man in a society that is increasingly shaped by digitalization and artificial intelligence. The purpose of this book is to describe abstraction, analogy, inference, plausibility and creativity as basic skills of cognitive information processing and prerequisites for autonomous informational action.
