Mayr, Philipp and Petras, Vivien (2008) Cross-concordances: terminology mapping and its effectiveness for information retrieval. World Library and Information Congress: 74th IFLA General Conference and Council, Québec, Canada.
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.
