www.isocat.org TTNWW and ISOcat • TTNWW: TST Tools voor het Nederlands als Web services in een Workflow • CLARIN-NL and VL pilot project • Goal: to enable researchers in the humanties to use our tools and resources in an easy way, even when a whole series of tools and resources is involved. 20 January 2012 CLIN22 - TTNWW Project 2

www.isocat.org TTNWW and ISOcat • Issues when making use of such a ‘chain’: – Is the meaning of notion X in resource/tool A the same as that in resource/tool B ? – Is the meaning of notion X in resource/tool A and that of Y in resource/tool B the same? – Or, if not the same, are they related? If so, how? = ISOcat and friends to the rescue ! 20 January 2012 CLIN22 - TTNWW Project 3

www.isocat.org Explicit semantics • Language resources are valuable assets – store them in an archive to assure persistency! – later generations can research material that only now can still be collected • Problem: used terminology might ‘rot’ – terms get a (slightly) different meaning over (long) periods of time – later generations need to know the meaning of today • Solution: make semantics explicit 20 January 2012 CLIN22 - TTNWW Project 4

www.isocat.org The ISOcat Data Category Registry http://www.isocat.org/ • An ISOcat data category is “an elementary descriptor in a linguistic structure or an annotation scheme” (ISO 12620:2009) • ISOcat data categories have unique and persistent identifiers, which can be resolved over the web http://www.isocat.org/datcat/DC-78 20 January 2012 CLIN22 - TTNWW Project 5

www.isocat.org Annotate all elements in a linguistic resource /lexicon/ /language/ /alphabet/ /entry/ /japanese/ /ipa/ /lemma/ /writtenForm/ 20 January 2012 CLIN22 - TTNWW Project 6

www.isocat.org Sharing structure • Using ISOcat data category references specifications of elementary descriptors can be shared between structures • How to share (annotated) structures? • A companion registry for ISOcat is under development: SCHEMAcat • This registry should persistently store any kind of schema, e.g., XML schemata, EBNF grammars 20 January 2012 CLIN22 - TTNWW Project 7

www.isocat.org Sharing relations • Among data categories and (other) concepts ontological relationships can be defined • These relationships allow crosswalks between various resource models – discover related resources which use (different levels of) semantically close data categories • RELcat is a companion registry which will allow storing (and sharing) a linguists individual view on these relationships http://lux13.mpi.nl/relcat/ (alpha) 20 January 2012 CLIN22 - TTNWW Project 9

www.isocat.org Conclusion • CLARIN(-NL/-VL), including TTNWW, is working towards a set of registries that enable the community to collaboratively make semantics explicit by: – sharing elementary descriptors: data categories • persistently – sharing structure: schemata • persistently – sharing ontological relations • individual world views 20 January 2012 CLIN22 - TTNWW Project 11
