3 Financially supported by: German Research Foundation
CrissCross – Overview Insights and Outlooks: A Retrospective View on the CrissCross Project 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 Cologne, 19th July 2010

4 Dewey Decimal Classification (DDC)
CrissCross – DDC Insights and Outlooks: A Retrospective View on the CrissCross Project Dewey Decimal Classification (DDC) 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, …) Cologne, 19th July 2010

5 German subject headings authority file Schlagwortnormdatei (SWD)
CrissCross – SWD Insights and Outlooks: A Retrospective View on the CrissCross Project German subject headings authority file Schlagwortnormdatei (SWD) 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 Cologne, 19th July 2010

14 CrissCross – Retrieval Scenarios
Insights and Outlooks: A Retrospective View on the CrissCross Project Retrieval Scenarios The mappings produced within the CrissCross project are first and foremost tools to optimize retrieval processes. Cologne, 19th July 2010 14

15 CrissCross – Retrieval Scenarios
Insights and Outlooks: A Retrospective View on the CrissCross Project CrissCross mappings can be used to enhance access to the DDC and to DDC-indexed documents to structure document sets (search result lists) to support conceptual exploration They can be used to enhance access to the DDC and to DDC-indexed documents, to structure document sets, and to support conceptual exploration. Cologne, 19th July 2010 15

16 CrissCross – Retrieval Scenarios
Insights and Outlooks: A Retrospective View on the CrissCross Project Enhancing access to DDC classes and DDC-indexed documents SWD DDC Polka-Mazurka UF Polka-Mazur BT Polka D2 Polkas Relative Index Terms: Polkas — Musik D2 Gesellschaftstänze (Rundtänze) (EN = Ballroom dancing (Round dances)) Relative Index Terms: Diskotanz Foxtrott Gesellschaftstänze Jitterbug Polkas Rumbas Rundtänze Sambas Tangos Turniertänze Walzer -In order to access DDC classes, the Relative Index of the DDC is a powerful aid. But the number of terms is limited. -The mapped headings (plus their synonyms) can function as verbal and topical entry points to DDC classes in addition to the Relative Index. The direction of the mappings is important. -An example is the heading “Polka-Mazurka” (with its synonym Polka-Mazur) which is mapped to the DDC classes Polkas (within the discipline music) and Gesellschaftstänze (Rundtänze) (EN=Ballroom dancing (Round dances), where you can also find dances other than Polkas, as you can see in the list of Relative Index Terms. Cologne, 19th July 2010

17 CrissCross – Structuring document sets by SWD headings
Insights and Outlooks: A Retrospective View on the CrissCross Project Gesellschaftstänze (Rundtänze) (EN = Ballroom dancing (Round dances)) DDC: AND SWD: Gesellschaftstanz DDC: AND SWD: Polka-Mazurka -A query for a DDC notation may produce many search results, but not all documents might be relevant to the user’s information need. For example, the information seeker may look for a specific topic that is one amongst other topics represented by a DDC class or he may be primarily interested in documents that treat the topic of a DDC class comprehensively. -In order to find documents that are most relevant to the overall topic of a DDC class, all documents with a heading mapped to this class with Degree 4 or 3 could be ranked accordingly high. For example, documents indexed with the D3-mapped heading “Gesellschaftstanz” (ballroom dancing) can be considered most relevant for the DDC class “ Ballroom dancing (Round dances)” whereas documents indexed with a more specific heading such as “Tango” could be ranked lower. -In this way document sets with a specific DDC number can be structured (and transparently presented as grouped search results) according to (mapped) headings and their Degree of Determinacy. DDC: AND SWD: Tango […] DDC: AND SWD: Bossa Nova Cologne, 19th July 2010 17

18 CrissCross – Structuring document sets by DDC notations
Insights and Outlooks: A Retrospective View on the CrissCross Project SWD heading: Kabelbrücke (EN = cable-stayed bridge) SWD: Kabelbrücke AND DDC: Suspension and cable-stayed bridges (discipline: Engineering) SWD: Kabelbrücke AND DDC: Bridges, tunnels, moats (discipline: Architecture) -A search result list for a heading query can also be structured with the help of CrissCross mappings. Such a result list can be grouped according to the mapped DDC numbers. Thus the document list could be structured by DDC disciplines. In the example for the heading Kabelbrücke (EN = cable-stayed bridge) the disciplines are Engineering, Architecture and Transportation. SWD: Kabelbrücke AND DDC: Bridges (discipline: Transportation) Cologne, 19th July 2010 18
