Abstract: This paper illustrates the changing role of thesauri interlinked with overall changes of modern information infrastructure services, referring to "STW Thesaurus for Economics" as a case study. It starts with an overview of the history and development of the STW and describes the far-reaching changes brought about by its publication on the Web, with regard to subject indexing, retrieval and new uses for Linked Open Data. It argues that only the most recent technological developments help thesauri to exploit their full potential which is why they more than ever have a place in current information retrieval and infrastructure.

Abstract

In economics there exists an internationally established classification system. Research literature is usually classified according to the JEL classification codes, a classification system originated by the Journal of Economic Literature and published by the American Economic Association (AEA). Complementarily to keywords which are usually assigned freely, economists widely use the JEL codes when classifying their publications. In cooperation with KU Leuven, ZBW - Leibniz Information Centre for Economics has published an unofficial multilingual version of JEL in SKOS format. In addition to this, exists the STW Thesaurus for Economics a bilingual domain-specific controlled vocabulary maintained by the German National Library of Economics (ZBW). Developed in the mid-1990s and since then constantly updated according to the current terminology usage in the latest international research literature in economics it covers all sub-fields both in the economics as well as in business economics and business practice containing subject headings which are clearly delimited from each other. It has been published on the web as Linked Open Data in the year 2009.

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

Efforts towards internationalization have become increasingly important in scientific environments. As for content-based indexing of scientific research data, however, standards leading to internationally coherent indexing which is vital for retrieval purposes are not yet sufficiently developed. Even concerning the concrete use of indexing instruments, launched by initiatives on an international scale, there are still no binding policies and guidelines. Against this backdrop, essential criteria which internationally applicable indexing systems should meet will be outlined. These will be illustrated through the multilingual European Language Social Science Thesaurus (ELSST), originally based on the UK Data Archive's (UKDA) Humanities and Social Science Electronic Thesaurus (HASSET) and ultimately developed by the Council of European Social Science Data Archives (CESSDA). Additionally, the general pros and cons of using international versus national indexing languages will be weighed using the ELSST and the Thesaurus for the Social Sciences (TSS) developed by GESIS - Leibniz-Institute for the Social Sciences. In this light, the benefit of vocabulary crosswalks for supporting a combined use of international and national indexing systems will be discussed.
