CLARIN K(nowledge)-Centres

One central element in building the CLARIN Knowledge Infrastructure is the establishment of Knowledge Centres. See below a table with the existing Knowledge Centres.

Any institute can apply for being recognized as a K-Centre -- existing technical CLARIN (B- and C-) Centres, but also institutes which are not (yet) part of CLARIN. It is not even necessary that the country of the institute be a member of CLARIN ERIC (already), and even not in Europe. K-Centres can also be distributed, that is, consist of a collaboration between more than one physical institute.

It is also possible for an institute to join an existing distributed knowledge centre if it has expertise in the same area. No formal aplication is needed in such a case; an endorsement of all partners in the distributed centre and an update of the services offered by the distributed centre as a whole is sufficient.

Probably, most existing CLARIN centres are able to get the status of a Knowledge Centre right away; the K-Centres rather formalize and centrally register the existing expertise but does usually not require much additional effort from an institute except that the knowledge-sharing services have to be reliable and their scope has to be made explicit on a dedicated web-page of the respective institute(s).

Tour de CLARIN: K-Centres

Part of the Tour de CLARIN initiative is dedicated to highlighting the work of the CLARIN Knowledge Centres. Each highlight includes a presentation of what the K-centre offers to researchers and an interview with either a renowned researcher who has collaborated with the K-centre or a leading developer who is part of the centre itself and who provided as with valuable insight into what the centre offers. Read more

SAFMORIL brings together researchers and developers in the area of computational morphology and its application during language processing. The focus lies on actual, working systems and frameworks based on linguistic principles and providing linguistically motivated analyses and/or generation on the basis of linguistic categories. Such systems are relevant in particular for languages with rich morphologies, e.g. Finno-Ugric and Inuit languages. 

SAFMORIL offers online courses for developing morphologies, tokenizers and spell-checkers, a repository for storing morphologies, and an environment for creating tokenizers and spell-checkers. The K-centre serves linguists and computational linguists developing and adapting morphologies as well as digital humanities scholars and computer scientists processing language data.
