CLARIN technology - an introduction

The technical pillars of the CLARIN infrastructure are:

  • Federated identity - letting users login to protected data and services with their own institutional login and password
  • Persistent identifiers - enabling sustainable citations of electronic resources
  • Sustainable repositories - digital archives where language resources can be stored, accessed and shared
  • Flexible metadata and concept definitions - to ensure semantic interoperability when describing language resources
  • Content search - offering a search engine for a wide range of language resources
  • Web service chaining - giving users the possibility to freely combine language processing services

The Services section gives an impression of how all these technological components are combined into ready-to-use packages for our scientific community.

Organization

CLARIN is based on a distributed network of organizations (‘centres’) that host language resources and related services. Currently there are 38 of these centres – mostly in  Europe – each with its own expertise. Within a single country these centres are grouped into a national consortium.

Each consortium has appointed one centre as a representative in CLARIN's technical body, the Centre Committee. That is were most of the technical work happens: writing specifications, planning software development and organizing the quality control for each of the centre candidates. The independent Center Assessment Committee will analyze each of the candidate centres and provide feedback with regards to compliancy to the technical and organizational requirements.
