lindat

lindat is a digital infrastructure and language data repository that provides access to linguistic resources and natural language processing tools. It serves researchers by hosting corpora, lexical resources, grammars, and software for processing language, and by offering long-term preservation, metadata, search, and download services.

Operated as a national and international collaboration, lindat forms part of the LINDAT/CLARIAH-CZ platform, a broader European infrastructure supporting humanities and social sciences. The platform aggregates language data from universities and research institutes, ensuring persistent identifiers, standardized metadata, and open access where permitted.

Content hosted on lindat includes a wide range of language data such as annotated corpora, dictionaries, grammars, word lists, and NLP tools like parsers and taggers. Access is provided through web interfaces and programmatic APIs, with options for bulk downloads and data sharing. Licensing varies: many items are available under open licenses, while some resources are restricted by publisher or contributor policies.

History and governance: lindat originated in the Czech Republic as a national repository for language data and research tools and later merged with CLARIAH to form LINDAT/CLARIAH-CZ, integrating with broader CLARIAH infrastructure to support interdisciplinary humanities research.

Impact and usage: the platform is widely used in linguistic research, corpus linguistics, and NLP education in Central Europe and beyond. It supports reproducible research by providing stable access to datasets and tools, and it serves as a key resource for researchers needing long-term preservation and sharing of language data.
