    Abstract
    Die Bewertung der Indexierungsqualität bzw. -güte ist ein grundlegendes Problem von manuellen und automatischen Indexierungsverfahren. Letztere werden aber gerade im digitalen Zeitalter als einzige Möglichkeit angesehen, den zunehmenden Schwierigkeiten bibliothekarischer Informationsstrukturierung gerecht zu werden. Diese Arbeit befasst sich mit der Funktionsweise, Implementierung und Evaluierung der Sacherschließungssoftware MindServer Categorizer, der Firma Recommind, an der Deutschen Zentralbibliothek für Wirtschaftswissenschaften (ZBW). Grundlage der maschinellen Sacherschließung und anschließenden quantitativen und qualitativen Auswertung bilden rund 39.000 wirtschaftswissenschaftliche Dokumente aus den Datenbanken Econis und EconStor. Unter Zuhilfenahme des rund 6.000 Deskriptoren umfassenden Standard-Thesaurus Wirtschaft (STW) wird der ursprünglich rein statistische Indexierungsansatz des MindServer Categorizer zu einem begriffsorientierten Verfahren weiterentwickelt und zur Inhaltserschließung digitaler Informationsressourcen eingesetzt. Der zentrale Fokus dieser Arbeit liegt vor allem auf der Evaluierung der maschinell beschlagworteten Titel, in Anlehnung und entsprechender Anpassung der von Stock (2008) und Lancaster (2003) hierzu vorgeschlagenen Kriterien: Indexierungskonsistenz, -tiefe, -breite, -spezifität, -effektivität. Zusätzlich wird die Belegungsbilanz des STW evaluiert und es erfolgt ferner eine stichprobenartige, qualitative Bewertung der Ergebnisse seitens der zuständigen Fachreferenten und -referentinnen.

    Abstract
    In the processes of information organization, information retrieval and information visualization one point in common can be found: they are strongly connected by the procedures associated to the indexing of texts or documents. Indexing is an essential component of text analysis, and the indexing process have equal importance both for retrieval and for the visualization of information. In this context, it is worth mentioning the solutions that use automatic indexing. The researches that proposes solutions for automatic indexing are based on different theoretical assumptions such as: statistics, linguistics and controlled vocabulary (Leiva 1999). Most solutions developed hybrid models combining these theoretical assumptions. Other solutions to the problem of automatic indexing are based on theories that allow the treatment of uncertainty, imprecision and vagueness. The aim of this paper is to argue the theoretical potential for use in hybrid models of automatic indexing, the paraconsistent logic, a non-classical logic, with capacity to handle situations that involve uncertainty, imprecision and vagueness.

    Abstract
    Describes an application of Natural Language Processing (NLP) techniques, in HIRMA (Hypertextual Information Retrieval Managed by ARIOSTO), to the problem of document indexing by referring to a system which incorporates natural language processing techniques to determine the subject of the text of documents and to associate them with relevant semantic indexes. Describes briefly the overall system, details of its implementation on a corpus of scientific abstracts related to environmental topics and experimental evidence of the system's behaviour. Analyzes in detail an experiment designed to evaluate the system's retrieval ability in terms of recall and precision

    Abstract
    In this article, we describe and test a two-stage algorithm based on a lexical collocation technique which maps from the lexical clues contained in a document representation into a controlled vocabulary list of subject headings. Using a collection of 4.626 INSPEC documents, we create a 'dictionary' of associations between the lexical items contained in the titles, authors, and abstracts, and controlled vocabulary subject headings assigned to those records by human indexers using a likelihood ratio statistic as the measure of association. In the deployment stage, we use the dictiony to predict which of the controlled vocabulary subject headings best describe new documents when they are presented to the system. Our evaluation of this algorithm, in which we compare the automatically assigned subject headings to the subject headings assigned to the test documents by human catalogers, shows that we can obtain results comparable to, and consistent with, human cataloging. In effect we have cast this as a classic partial match information retrieval problem. We consider the problem to be one of 'retrieving' (or assigning) the most probably 'relevant' (or correct) controlled vocabulary subject headings to a document based on the clues contained in that document

    Abstract
    Die Deutsche Nationalbibliothek (DNB) erstellt für Netzpublikationen seit Anfang 2010 keine intellektuell per Autopsie und nach gültigem Regelwerk (RAK-WB bzw. RAK-NBM) erschlossen Titeldaten mehr. Da das stetig wachsende Kontingent an Netzpublikationen durch intellektuelle Bearbeitung nicht mehr zu bewältigen ist, wurde mit dem Projekt PETRUS damit begonnen, die Erschließungsprozesse für Netzpublikationen zu automatisieren.
