Abstract

Das Bundesministerium für Bildung und Forschung hat eine große Initiative zur Erstellung von Crosskonkordanzen gefördert, die 2007 zu Ende geführt wurde. Die Aufgabe dieser Initiative war die Organisation, die Erstellung und das Management von Crosskonkordanzen zwischen kontrollierten Vokabularen (Thesauri, Klassifikationen, Deskriptorenlisten) in den Sozialwissenschaften und anderen Fachgebieten. 64 Crosskonkordanzen mit mehr als 500.000 Relationen wurden umgesetzt. In der Schlussphase des Projekts wurde eine umfangreiche Evaluation durchgeführt, die die Effektivität der Crosskonkordanzen in unterschiedlichen Informationssystemen testen sollte. Der Artikel berichtet über die Crosskonkordanz-Arbeit und die Evaluationsergebnisse.

Abstract

In der Studie sind 3.889 Datensätze analysiert worden, die im Zeitraum 1976-2004 in der Datenbank Library and Information Science Abstracts (LISA) im Forschungsbereich der Informetrie nachgewiesen sind und das Wachstum auf diesem Gebiet belegen. Die Studie zeigt anhand einer Bradford-Verteilung (power law) die Kernzeitschriften in diesem Feld und bestätigt auf der Basis dieses LISA-Datensatzes, dass die Gründung einer neuen Zeitschrift, "Journals of Informetrics" (JoI), 2007 etwa zur rechten Zeit erfolgte. Im Verhältnis dazu wird die Entwicklung der Zeitschrift Scientometrics betrachtet und auch die der "Nachrichten für Dokumentation" (NfD) bzw. "Information - Wissenschaft und Praxis" (IWP).

Abstract

In 2004, the German Federal Ministry for Education and Research funded a major terminology mapping initiative at the GESIS Social Science Information Centre in Bonn (GESIS-IZ), which will find its conclusion this year. The task of this terminology mapping initiative was to organize, create and manage 'crossconcordances' between major controlled vocabularies (thesauri, classification systems, subject heading lists) centred around the social sciences but quickly extending to other subject areas. Cross-concordances are intellectually (manually) created crosswalks that determine equivalence, hierarchy, and association relations between terms from two controlled vocabularies. Most vocabularies have been related bilaterally, that is, there is a cross-concordance relating terms from vocabulary A to vocabulary B as well as a cross-concordance relating terms from vocabulary B to vocabulary A (bilateral relations are not necessarily symmetrical). Till August 2007, 24 controlled vocabularies from 11 disciplines will be connected with vocabulary sizes ranging from 2,000 - 17,000 terms per vocabulary. To date more than 260,000 relations are generated. A database including all vocabularies and cross-concordances was built and a 'heterogeneity service' developed, a web service, which makes the cross-concordances available for other applications. Many cross-concordances are already implemented and utilized for the German Social Science Information Portal Sowiport (www.sowiport.de), which searches bibliographical and other information resources (incl. 13 databases with 10 different vocabularies and ca. 2.5 million references).

Abstract

The German Federal Ministry for Education and Research funded a major terminology mapping initiative, which found its conclusion in 2007. The task of this terminology mapping initiative was to organize, create and manage 'cross-concordances' between controlled vocabularies (thesauri, classification systems, subject heading lists) centred around the social sciences but quickly extending to other subject areas. 64 crosswalks with more than 500,000 relations were established. In the final phase of the project, a major evaluation effort to test and measure the effectiveness of the vocabulary mappings in an information system environment was conducted. The paper reports on the cross-concordance work and evaluation results.
