ACL Expresses Concern about New Executive Order Concerning Immigration

The Association for Computational Linguistics (ACL), a global scientific and educational organization representing the natural language processing community, expresses strong disagreement with U.S. Presidential Executive Order 13769, which imposes a 90-day suspension of visas to nationals of seven countries and additional examination of current green card and visa holders from those countries.


What is computational linguistics?

Computational linguistics is the scientific study of language from a computational perspective. Computational linguists are interested in providing computational models of various kinds of linguistic phenomena. These models may be "knowledge-based" ("hand-crafted") or "data-driven" ("statistical" or "empirical"). Work in computational linguistics is in some cases motivated from a scientific perspective in that one is trying to provide a computational explanation for a particular linguistic or psycholinguistic phenomenon; and in other cases the motivation may be more purely technological in that one wants to provide a working component of a speech or natural language system. Indeed, the work of computational linguists is incorporated into many working systems today, including speech recognition systems, text-to-speech synthesizers, automated voice response systems, web search engines, text editors, language instruction materials, to name just a few.

Popular computational linguistics textbooks include:
