Sample: work done for Arabic resources within NEMLAR project: http://www.nemlar.org

Basic LAnguage Resource Kit (BLARK)
validation and quality assessment
Users need info on LRs: technical specifications, assurance of quality,...

Validation is used by ELRA in reference to: checking the adherence to standards, QC of LRs, suitability for market

Definition of validation methodology required:

Projects for the production of guidelines, standards and specifications: EAGLES, PAROLE, SPEECHDAT, INTERVAL, ...

Establishment of a Validation Committee (VCom)

SPEX (for speech resources): http://www.spex.nl/validationcentre/

CST (for written resources): http://cst.dk/validation/index.html
