  1. 1. University Library / Theological FacultiesThe Theological Subject HeadingsCatalogue for Gender Studies2012-12-26 Philipp Baar
  2. 2. Universitätsbibliothek Bochum The catalogue • The Theological Subject Headings Catalogue for Gender Studies is a datasource, which focuses on Feminist Theology and Gender Studies. • Articles, books and journals along with many online full-texts can be found grouped under approx. 7.500 subject headings • Currently we are working on making it searchable in Solr and making its subject headings and bibliographic metadata available as Linked Open Data 2
  3. 3. Universitätsbibliothek Bochum The clean up • There was an old version of the catalogue, containing much (16.000 titles), but rather messy data • We cleaned up, organizing the subject headings in 5 categories: • Topics • Temporals • Geographicals • Persons • Scripture Citations 3
  4. 4. Universitätsbibliothek Bochum Organizing the subject headings • For each category (except Persons) we built a thesaurus, organizing the subject headings among each other and linked them to dbpedia • Using SKOS as the main vocabulary for the topical subject headings, we got resources looking like this: 4
  5. 5. Universitätsbibliothek Bochum Organizing the subject headings (topicals)<http:://femtheol.ub.rub.de/thesaurus/topical/> a skos:Collection; skos:member <http://femtheol.ub.rub.de/thesuarus/homosexualitat>;<http://femtheol.ub.rub.de/thesuarus/homosexualitat> a skos:Concept; skos:inScheme <http://femtheol.ub.rub.de/thesaurus/>; skos:prefLabel "Homosexualität"@de; skos:broader <http://femtheol.ub.rub.de/thesuarus/sexualitat>; owl:sameAs <http://dbpedia.org/resource/Homosexuality>.<http://femtheol.ub.rub.de/thesuarus/coming-out> skos:related <http://femtheol.ub.rub.de/thesuarus/homosexualitat>. 5
  6. 6. Universitätsbibliothek Bochum Mapping problems • For the non-topical subject headings, SKOS was used for naming the collections: <http://femtheol.ub.rub.de/thesaurus/temporal/> a skos:Collection; skos:member <http://femtheol.ub.rub.de/thesaurus/1989> • We made the geographicals to a „skos:concept“ and a „skos:member“ of our collection, then linked them to geonames (and dbpedia) with „owl:sameAs“, planning to harvest information like „a is a city in country b“ automatically • For building thesaurus structures with the temporals, we looked for alternative ontologies, finally using cidoc-crm, getting resources like: 6
  7. 7. Universitätsbibliothek Bochum<http://femtheol.ub.rub.de/thesaurus/19-jahrhundert> a skos:Concept; a crm:E55_Type; a crm:E4_Period; skos:inScheme <http://femtheol.ub.rub.de/thesaurus/>; skos:prefLabel "19. Jahrhundert"@de; owl:sameAs <http://openlink.dbpedia.org/resource/19th_century>; crm:P120i_occurs_after <http://femtheol.ub.rub.de/thesaurus/18- jahrhundert>; crm:P120_occurs_before <http://femtheol.ub.rub.de/thesaurus/20- jahrhundert>. 7
  8. 8. Universitätsbibliothek Bochum The personal subject headings • We further differentiated the personal subject headings in „real/historical“ persons and biblical persons (not implemented in the catalogue yet). • So for each personal subject heading we had to note that the entity is a person and for some that the person is a biblical figure. • This time we used CRM again, plus the ontology of the German National Librarys linked data service, which provides the type „biblical person“ that just has to be marked as a „crm:E55_Type“ and added to the person-attribute if the subject heading names a biblical person: 8
  9. 9. Universitätsbibliothek Bochum The Personal subject headings <http://d-nb.info/gnd/4006473-6/about/rdf> a crm:E55_Type. <http://femtheol.ub.rub.de/thesuarus/paulus> a crm:E21_Person. crm:P2_has_type <http://d-nb.info/gnd/4006473- 6/about/rdf>. owl:sameAs <http://dbpedia.org/resource/Paul_the_Apostle>. 9
  10. 10. Universitätsbibliothek Bochum The new version of the catalogue • Currently, the catalogue contains about 800 titles, plus their subject headings • We have not set up a triple store yet, neither have we implemented a browsable thesaurus but we are working on having it ready by the end of the year. • Bibliographic metadata will be available as FRBRoo. Were working on that too... • Nevertheless we already now benefit from linked data: 10
  11. 11. Universitätsbibliothek Bochum The benefits • The search engine can deal with queries in every language listed in the respective dbpedia resource as „rdfs:label“, even things like “ チャーチ“ („church”) • The search engine expands queries containing keywords mentioned in the „dbpedia-owl:abstract“ • A short demonstration → http://femtheol.ub.rub.de/ 11
