  3. 3. Agenda Digital Humanities Research Project Methodology Research ontology Future Work Digital Humanities „What does the research field of Digital Humanities comprise?“ Digital Use of information systems and information technologies e.g. text systems, databases, decision support systems, 3D-scan, virtual reality ... Humanities Comprises about 40 different disciplines, which investigate with different methods in research areas like History, Linguistics and languages, Law and politics, Literature, Religion, ... Development towards the Digital Humanities Available knowledge services provided by libraries Web of Data ... 3 / 19
  4. 4. Agenda Digital Humanities Research Project Methodology Research ontology Future Work Challenges for Digital Humanities The use of information technologies within the humanities currently primarily supports the documentation and discussion of research processes and results. New opportunities for the humanities, such as: Formal representation Parallel work on the same research topics Reuse of research data Challenges: No established methodologies for research on data repositories comparing to research in archives and libraries Reuse of „unpublished“ data or inferred facts Expertise in computer science and information science is necessary 4 / 19

  9. 9. Agenda Digital Humanities Research Project Methodology Research ontology Future Work Research question Early Modern Professorial Career Patterns Research and linking of research databases Professor catalogues Enrolment or students catalogues Maps, Geo-Data Publications, scholarly journals, .... Relevant criteria for answering the research question: Basics: name, birth and death dates, places the prof lived and worked origin (family, social status, geographical origin) denomination education or educational CV (schools, faculties, chairs) academic degrees academic and non academic offices social entanglements and networks academic collections academic capital (prestige) 9 / 19

  14. 14. Agenda Digital Humanities Research Project Methodology Research ontology Future Work Development of a research ontology Modelling of relevant concepts in the form of classes, relationships and attributes from the point of view of the research question in the form of a research vocabulary. Import, integration or alignment of relevant facts to the research vocabulary. 14 / 19
  15. 15. Agenda Digital Humanities Research Project Methodology Research ontology Future Work Classical ways of modelling vocabularies From the general model to the specific application Usually starting from the graph and tables using a visual Editor From the use case (object) to the general model Usually starting text or forms using a form editor 15 / 19
  16. 16. Agenda Digital Humanities Research Project Methodology Research ontology Future Work Modelling concepts of existing knowledgebases (1) Making the data available as RDF database (Triple-Store) (2) Exploration of the database through relevant natural language queries (historical studies) (3) Conversion of queries as SPARQL query (computer science) (4) Documentation of the request pairs (5) Extraction of relevant concepts from the formal SPARQL representation First results in the project: First steps on development of a research vocabulary Description of relevant prosopographical concepts Integration of data from two professor catalogues 16 / 19
  17. 17. Agenda Digital Humanities Research Project Methodology Research ontology Future Work Future Work - Historical sciences In the context of the historical sciences and library services Simplify the exploration of unknown databases by aligning to Data publishing standards Domain independent standards (e.g. Dublin Core) Domain specific standards (e.g. CIDOC CRM, Data for History http://dataforhistory.org/) Quantitative measurement methods (number of facts, concepts, ...) Qualitative measurement methods (similar resources, missing concepts, contradictions) Traceability of the source of a fact e.g. documentation of the research process 17 / 19
  18. 18. Agenda Digital Humanities Research Project Methodology Research ontology Future Work Future Work – Computer Science In the context of computer sciences and library services Documentation and publishing research results using tools or tool chains Domain specific tools Implementing incremental and iterative methodologies Interchangeability between cloud services and specific implemented applications Easy maintenance, etc. with container virtualization (Docker) Establishing research infrastructures in libraries, data centers, CLARIAH, DFN-Cloud, European Science Cloud Additional motivation Relevant open and comparable data for applying research results in computer science (benchmarks) 18 / 19
