CLARIN offers central services that can be directly accessed via this website. These include services to search for and in resources (data and tools) offered via CLARIN, create collections, or apply online web-services and applications. You find a good overview on the pages for the individual services (see the service page) and in the general section of the frequently asked questions.
If you plan or carry out a research project that involves digital language data and tools, you can get in contact with one of the CLARIN Centres to get advice and possibly plan a collaboration. This holds in particular if you plan to deposit the data or tools resulting of your project in a CLARIN Centre later. Many CLARIN centres are a good partner for Data Management Plans (DMPs) and other aspects of research projects.
For general questions on digital language data and tools, you can consult CLARIN directly by writing to email@example.com. If the Central Office cannot answer your question right away, we will forward it to one or several CLARIN centres where people may be able to provide the needed information. You can also get in direct contact with a CLARIN Knowledge Centre if your question concerns one of the areas of their expertise.
There are several showcases that demonstrate how people have successful made use of components of the CLARIN infrastructure. See also the Lingua - special issue on CLARIN (open access), with seven articles that present original research conducted by using one or more of the services that CLARIN offers. Lingua, Volume 178, pages 1-126 (July 2016).
