1 Cologne, 19 th July 2010 Insights and Outlooks: A Retrospective View on the CrissCross Project Katrin Müller, Jan-Helge Jacobs, Tina Mengel Cologne University of Applied Sciences, Institute of Information Management

2 Insights and Outlooks: A Retrospective View onthe CrissCross Project CrissCross – Overview Cologne, 19 th July 2010 The Project DDC SWD Mapping Methods Retrieval Scenarios Perspectives

3 Insights and Outlooks: A Retrospective View onthe CrissCross Project CrissCross – Overview Cologne, 19 th July 2010 Aim: … creation of a thesaurus-based, user-friendly research vocabulary that facilitates search in heterogeneously indexed collections by mapping topical headings of the German subject headings authority file Schlagwortnormdatei (SWD) and the Dewey Decimal Classification (DDC) Duration: 2006 – 2010 Conducted by: German National Library Cologne University of Applied Sciences Financially supported by: German Research Foundation

4 Insights and Outlooks: A Retrospective View onthe CrissCross Project CrissCross – DDC Cologne, 19 th July 2010 most widely used universal classification system used by 200,000 libraries in over 135 countries translated into more than 30 languages since 2006 used by the German National Library (DNB) for subject indexing contains about 50,000 classes structured by disciplines (e.g. religion, social sciences, technology, …) Dewey Decimal Classification (DDC)

5 Insights and Outlooks: A Retrospective View onthe CrissCross Project CrissCross – SWD Cologne, 19 th July 2010 universal indexing language contains 550,000 headings categories: geographical names, topical headings, time, form, … structured in 37 subject groups types of relations: equivalent, hierarchical and associative German subject headings authority file Schlagwortnormdatei (SWD)

6 Insights and Outlooks: A Retrospective View onthe CrissCross Project CrissCross – Mapping Methods Cologne, 19 th July 2010 One-to-many strategy Deep level mapping Degrees of Determinacy Guidelines:

9 Insights and Outlooks: A Retrospective View onthe CrissCross Project CrissCross – Mapping Methods – Degrees of Determinacy Cologne, 19 th July 2010 indicate conceptual congruency between SWD term and DDC class 4 degrees from full to partial coverage Degrees of Determinacy (D)

10 Insights and Outlooks: A Retrospective View onthe CrissCross Project CrissCross – Mapping Methods – Degrees of Determinacy Cologne, 19 th July 2010 Steppe animals = Degrees of Determinacy (D) D4: full congruency D3: high congruency Diving medicine Submarine medicine
