CLARIN stands for Common LAnguage Resources and Technology INfrastructure. It is a European Research Infrastructure for the Humanities and Social Sciences, focusing on language resources and language tools. It is being implemented and constantly improved at leading institutions in more than twenty European countries, aiming at improving Europe's multilingual competence.

Currently CLARIN provides easy and sustainable access to digital language data (in written, spoken, or multimodal form) for scholars in the social sciences and humanities, and beyond.

CLARIN also offers advanced tools to discover, explore, exploit, annotate, analyse or combine such data sets, wherever they are located. This is enabled through a networked federation of centres: language data repositories, service centres and knowledge centres, with single sign‑on access for all members of the academic community in all participating countries. Tools and data from different centres are interoperable, so that data collections can be combined and tools from different sources can be chained to perform complex operations to support researchers in their work.

The CLARIN infrastructure is fully operational in many countries, and a large number of participating centres are offering access services to data, tools and expertise. At the same time, CLARIN continues to be constructed in some countries that joined more recently, and CLARIN’s datasets and services are constantly updated and improved.

HR‑CLARIN is the national consortium of the European research infrastructure CLARIN. HR‑CLARIN provides language resources and technologies and expertise as well as knowledge transfer to researchers from Humanities and Social Sciences with the focus on Croatian language resources and tools, but develops language technologies other languages also.
