Abstract: The Open Linguistics Working Group (OWLG) is an initiative of experts from different fields concerned with linguistic data, including academic linguistics (e.g. typology, corpus linguistics), applied linguistics (e.g. computational linguistics, lexicography and language documentation) and NLP (e.g. from the Semantic Web community). The primary goals of the working group are 1) the promotion of the idea of open linguistic resources 2) the development of means for their representation, and 3) encouraging the exchange of ideas across different disciplines.
