    Abstract
    Automatische Indexierungsverfahren werden mit Zunahme der digitalen Verfügbarkeit von Metadaten und Volltexten mehr und mehr als eine mögliche Antwort auf das Management unstrukturierter Daten diskutiert. In der sozialwissenschaftlichen Fachinformation existiert in diesem Zusammenhang seit einiger Zeit der Vorschlag eines sogenannten Schalenmodells (vgl. Krause, 1996) mit unterschiedlichen Qualitätsstufen bei der inhaltlichen Erschließung. Vor diesem Hintergrund beschreibt die Arbeit zunächst Methoden und Verfahren der inhaltlichen und automatischen Indexierung, bevor vier Testläufe eines automatischen Indexierungssystems (MindServer) zur automatischen Erschließung von Datensätzen der bibliographischen Literaturdatenbank SOLIS mit Deskriptoren des Thesaurus Sozialwissenschaften sowie der Klassifikation Sozialwissenschaften beschrieben und analysiert werden. Es erfolgt eine ausführliche Fehleranalyse mit Beispielen sowie eine abschließende Diskussion, inwieweit die automatische Erschließung in dieser Form für die Randbereiche der Datenbank SOLIS für die Zukunft einen gangbaren Weg darstellt.

    Abstract
    Der Artikel basiert auf einer Masterarbeit mit dem Titel "Automatische Indexierung in der sozialwissenschaftlichen Fachinformation. Eine Evaluationsstudie zur maschinellen Erschließung für die Datenbank SOLIS" (Kempf 2012), die im Rahmen des Aufbaustudiengangs Bibliotheks- und Informationswissenschaft an der Humboldt- Universität zu Berlin am Lehrstuhl Information Retrieval verfasst wurde. Auf der Grundlage des Schalenmodells zur Inhaltserschließung in der Fachinformation stellt der Artikel Evaluationsergebnisse eines automatischen Erschließungsverfahrens für den Einsatz in der sozialwissenschaftlichen Fachinformation vor. Ausgehend von dem von Krause beschriebenen Anwendungsszenario, wonach SOLIS-Datenbestände (Sozialwissenschaftliches Literaturinformationssystem) von geringerer Relevanz automatisch erschlossen werden sollten, wurden auf dieser Dokumentgrundlage zwei Testreihen mit der Indexierungssoftware MindServer der Firma Recommind durchgeführt. Neben den Auswirkungen allgemeiner Systemeinstellungen in der ersten Testreihe wurde in der zweiten Testreihe die Indexierungsleistung der Software für die Rand- und die Kernbereiche der Literaturdatenbank miteinander verglichen. Für letztere Testreihe wurden für beide Bereiche der Datenbank spezifische Versionen der Indexierungssoftware aufgebaut, die anhand von Dokumentkorpora aus den entsprechenden Bereichen trainiert wurden. Die Ergebnisse der Evaluation, die auf der Grundlage intellektuell generierter Vergleichsdaten erfolgt, weisen auf Unterschiede in der Indexierungsleistung zwischen Rand- und Kernbereichen hin, die einerseits gegen den Einsatz automatischer Indexierungsverfahren in den Randbereichen sprechen. Andererseits deutet sich an, dass sich die Indexierungsresultate durch den Aufbau fachteilgebietsspezifischer Trainingsmengen verbessern lassen.

    Abstract
    On a scientific concept hierarchy, a parent concept may have a few attributes, each of which has multiple values being a group of child concepts. We call these attributes facets: classification has a few facets such as application (e.g., face recognition), model (e.g., svm, knn), and metric (e.g., precision). In this work, we aim at building faceted concept hierarchies from scientific literature. Hierarchy construction methods heavily rely on hypernym detection, however, the faceted relations are parent-to-child links but the hypernym relation is a multi-hop, i.e., ancestor-to-descendent link with a specific facet "type-of". We use information extraction techniques to find synonyms, sibling concepts, and ancestor-descendent relations from a data science corpus. And we propose a hierarchy growth algorithm to infer the parent-child links from the three types of relationships. It resolves conflicts by maintaining the acyclic structure of a hierarchy.

    Abstract
    Die Deutsche Zentralbibliothek für Wirtschaftswissenschaften - Leibniz-Informationszentrum Wirtschaft hat im Herbst 2011 die Version 8.08 des Standard-Thesaurus Wirtschaft (STW) veröffentlicht und damit einen weiteren Meilenstein in ihrer Linking-Open-Data-Strategie erreicht. Der STW enthält nun erstmals Verbindungen zu vier weiteren Vokabularen in der Linked Open Data Cloud. Es wurden Kreuzkonkordanzen geschaffen zur Schlagwortnormdatei (SWD), zum Thesaurus Sozialwissenschaften, der alle Disziplinen der Sozialwissen schaften abdeckt und zur Erschließung in den Datenbanken SOFIS und SOLIS genutzt wird, zu AGROVOC, dem mehrsprachigen Thesaurus der FAO - Ernährungs- und Landwirtschafts organisation der Vereinten Nationen für den Bereich der Agrarwissenschaften, Forst wirt schaft, Fischerei, Nahrungsmittel und verwandter Gebiete wie Ernährung und Umwelt, sowie zu DBpedia, einem Gemeinschaftsprojekt der Universität Leipzig, der Freien Universität Berlin und OpenLink Software (Burlington USA), zur Extraktion strukturierte Informationen aus Wikipedia für andere Web-Anwendungen.

    Abstract
    While classifications are heavily used to categorize web content, the evolution of the web foresees a more formal structure - ontology - which can serve this purpose. Ontologies are core artifacts of the Semantic Web which enable machines to use inference rules to conduct automated reasoning on data. Lightweight ontologies bridge the gap between classifications and ontologies. A lightweight ontology (LO) is an ontology representing a backbone taxonomy where the concept of the child node is more specific than the concept of the parent node. Formal lightweight ontologies can be generated from their informal ones. The key applications of formal lightweight ontologies are document classification, semantic search, and data integration. However, these applications suffer from the following problems: the disambiguation accuracy of the state of the art NLP tools used in generating formal lightweight ontologies from their informal ones; the lack of background knowledge needed for the formal lightweight ontologies; and the limitation of ontology reuse. In this dissertation, we propose a novel solution to these problems in formal lightweight ontologies; namely, faceted lightweight ontology (FLO). FLO is a lightweight ontology in which terms, present in each node label, and their concepts, are available in the background knowledge (BK), which is organized as a set of facets. A facet can be defined as a distinctive property of the groups of concepts that can help in differentiating one group from another. Background knowledge can be defined as a subset of a knowledge base, such as WordNet, and often represents a specific domain.
