The international conference series "Finite-State Methods and Natural Language Processing" (FSMNLP) is the premier forum of the ACL Special Interest Group on Finite-State Methods (SIGFSM). SIGFSM serves researchers and practitioners in natural language processing (NLP) working on:

natural language processing (implementation, applications, language resources),
theoretical aspects, or
combinations thereof,
that have obvious relevance or an explicit relation to finite-state methods.

For FSMNLP 2019 there is no conference fee. But, please, do register not later than September 10, 2019.
