An Ecosystem for Linked Humanities Data [chapter]

Rinke Hoekstra, Albert Meroño-Peñuela, Kathrin Dentler, Auke Rijpma, Richard Zijdeman, Ivo Zandhuis
2016 Lecture Notes in Computer Science  
The key enabler for such studies is the availability of sufficiently well described data. For the field of socio-economic history, data usually comes in a tabular form.  ...  QBer allows researchers to publish their (small) datasets, link them to existing vocabularies and other datasets, and thereby contribute to a growing collection of interlinked datasets.  ...  Acknowledgements This work was funded by the CLARIAH project of the Dutch Science Foundation (NWO) and the Dutch national programme COMMIT.  ...
