Instituut voor de Nederlandse Taal

What Instituut voor de Nederlandse Taal does

The Instituut voor de Nederlandse Taal (INT), also operating as the Dutch Language Institute, is a publicly funded research institute headquartered in Leiden, Netherlands, and the mandated authoritative body for the Dutch language under the Taalunie (the Dutch-Flemish intergovernmental union). Founded in 1967 as the Instituut voor Nederlandse Lexicologie (INL) and re-scoped in 2016 to its current broader mandate, INT documents Dutch across 15 centuries — from Old Dutch (6th century) to contemporary media — through 58+ web applications spanning dictionaries (ANW, GTB historical dictionaries, WNW neologisms, Etymologiebank), corpora (CHN with 2.5M+ texts, Corpus Middelnederlands, Corpus Oudnederlands, Historical Corpus of Dutch, Couranten Corpus), lexical databases (Cornetto, DiaMaNT, GiGaNT, PAROLE), terminology tools (TermWerk, Vertaalwoordenschat), grammar references (e-ANS, Taalportaal), and research tools (GrETEL 4, AutoSearch, Transcriptor, Text2Picto). The technology stack combines corpus compilation, lexical databases, computational linguistics, and applied NLP/AI (including the SignON sign-language machine translation project). All resources are freely accessible under FAIR principles; the institute is CLARIN-B centre certified and CoreTrustSeal certified, embedded in five European research infrastructure networks (CLARIN, ELEXIS, CLARIAH, European Language Data Space, ENEOLI/UniDive) and supported by Fryske Akademy, KANTL, NWO, and Taalunie. It employs ~37 staff and is led by Director Prof. dr. Sjef Barbiers. Revenue is institutional: Taalunie core funding supplemented by European research grants including a €16.8M NWO award (Nov 2025) for the Macroscope project. End users — researchers, students, teachers, translators, terminologists, journalists, and the general public — are not charged; the "customers" are effectively the Dutch and Flemish governments and EU research programs.

Broad incumbents

• CNRS (Centre National de la Recherche Scientifique): France's largest public research organization with extensive linguistics and computational language research. Comparable as a publicly funded research entity hosting large-scale language research infrastructure, though broader in scope.
• Oxford University Press: Major academic and reference publisher producing language reference works, dictionaries, and linguistic research. Comparable as a publisher of authoritative language reference content, though commercially operated and broader in scope.
• Oxford English Dictionary (OED): The preeminent English dictionary and historical language record, comparable as a comprehensive historical and contemporary English language reference. While commercial and English-focused, it parallels INT's role in historical and modern language documentation.

Directly comparable as a national language research institute with analogous public funding, mandate, and research infrastructure role for German.
