•  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?
