1 Linked Data for Digital History Connecting Data for Research Victor de Boer With input from Christophe Guéret, Serge ter Braake, Niels Ockeloen, Antske Fokkens, Dirk Roorda, Lora Aroyo, Johan Oomen, Oana Inel, Jan Wielemaker, Jeroen Entjes

3 Digital History Sub-discipline of digital humanities Part of the effort of historian is moved from the physical archives to digital ones Cross-domain collaboration Img:

6 Aging Data Tool C. Guéret based on

7 Even better Do not bake the data into the tool and treat data as an end product. Build tools on top of the data. Make sure others can do so as well. Fig: C. Guéret

8 Linked Data for Digital History Represent heterogeneous datasets with their own data models in common format: Resource Description Format (RDF) Link what can be linked PLACE CONCEPT re-use and re-usability OBJECT EVENT PERSON PROVENANCE TIME Linked Data is the (technically) best way to publish and share your (research) data

9 Some examples

10 Dutch Ships and Sailors

11 The Problem: ((Maritime) historical) data is not integrated

22 BiographyNet Starting Point: Biography Portal of the Netherlands; 125,000 short biographical descriptions with limited metadata from 23 Dutch biographical dictionaries (~76,000 individuals) What kind of historical questions can be answered with these data with the help of computational methods Biographynet.nl

26 Framework generic solutions with historians 1. Preprocess, Clean, Model, Link, Enrich data in a collaboration with domain experts 2. Access heterogeneous datasets in a convenient way to get an intuition of the character and anomalies of the (linked) data; 3. Perform arbitrary queries to retrieve results relevant to their research questions; 4. Verify the veracity of query results, by following provenance links to original material 5. Retrieve and analyze the data with tool of preference. 6. Republish and share results

27 Historical tool criticism willingness from historians to invest the time to learn about computer processes (at least the basic principles) Why do we still teach history student to decipher 17th Century handwriting, but not SQL Possibilities for education at universities to bridge the gap between computer science and humanities studies and make tool criticism an integral part of student s curricula
