•  Models drift over time •  Classes merge, split, change their properties

(beroepklassen) •  Although, some core meaning remains

(shoemakers) •  Can we automatically identify and align drifted

concepts? With what vocabulary/semantics?

Evalua&on •  Exis&ng (classical) research results on Humani&es datasets

•  We use them as gold standards •  Itera&ve refinement process

Research Ques&ons We aim at providing algorithms, formalisms and tools to disambiguate, clean, prepare, normalize, transform, link and query Humani&es datasets, conforming a framework for effec&ve Humani&es data publishing in the Seman&c Web.

•  Can RDF data models faithfully represent Humani&es datasets? Is an RDF-‐based format round-‐tripping framework possible?

•  How can we model concept dria? Can driaed concepts be aligned?

•  Can we infer dynamic concept defini&ons from explicitly formalized contexts? Can these contexts help solving concept dria?
