NAACL is the Nations of the Americas Chapter of the Association for Computational Linguistics (ACL), and also the name of the chapter’s annual conference. This page is for researchers and students in language technology who need to know what the venue is, where the next meeting is, how submission works, and where to find its papers. Facts below come from the chapter and conference sites and the ACL Anthology, checked on 2026-11-07.
What NAACL is (and the 2024 rename)
NAACL stands for the Nations of the Americas Chapter of the ACL. Until 2024 it was the North American Chapter; the chapter’s own site describes the rename as following a 2024 membership vote, and the ACL Anthology records the older name through October 2024. The abbreviation stayed the same. That is why older papers, citations and many search results still say “North American Chapter”.
NAACL is not NAACLS
NAACLS stands for National Accrediting Agency for Clinical Laboratory Sciences, according to its own site (naacls.org). It is an unrelated organisation in clinical laboratory science education and accreditation. If you arrived looking for that body, this page does not cover it.
Who runs it and what it covers
According to the chapter site (naacl.org), the chapter provides a regional focus for ACL members in North, Central and South America, organizes the annual conference, promotes cooperation with related societies, encourages ACL membership, and informs the ACL Executive Committee of regional matters. The chapter publishes its current officers and its constitution on the same site. The subject matter is the one ACL covers: computational linguistics and natural language processing. For a general orientation to the underlying field, see what is linguistics and what is artificial intelligence.
NAACL 2027: location, tracks and deadlines
Where will the NAACL 2027 conference be held?
San Francisco, California, USA, from June 1 to 5, 2027, according to the conference site (2027.naacl.org). The chapter site lists no 2026 conference.
Tracks and timetable
The 2027 site lists these tracks: main conference papers, system demonstrations, an industry track, tutorials and workshops. All deadlines are 11:59 pm UTC-12 (anywhere on earth). The consolidated dates below are those shown on the site on 2026-11-07; the site is the authority if they change.
| Step | Date |
|---|---|
| Workshop proposals due | September 4, 2026 |
| Main conference submission deadline (via ACL Rolling Review) | October 12, 2026 |
| Industry track submission deadline | November 13, 2026 (revised from October 31) |
| Tutorial acceptance notification | November 25, 2026 |
| System demonstration submission deadline | December 4, 2026 |
| NAACL commitment deadline | December 23, 2026 |
| Notification: main conference and system demonstrations | February 10, 2027 |
| Notification: industry track | February 24, 2027 |
| Camera-ready papers due (main, system demonstrations) | March 3, 2027 |
| Conference | June 1-5, 2027 |
Submission through ARR, then commitment
Main-conference papers are submitted through ACL Rolling Review (ARR), the shared submission and review pipeline used by ACL-family venues (ACL, EACL, EMNLP and NAACL). The conference then has a separate “commitment” deadline: authors whose paper has been through ARR review commit it to NAACL for consideration. ARR’s author guidelines state that submissions over the length limit, or missing a limitations section, are desk rejected. Read the current call at aclrollingreview.org before submitting; for how conference papers differ from journal articles, see conference paper vs journal article structure.
How to find NAACL papers
NAACL proceedings are indexed in the ACL Anthology under the venue identifier naacl (aclanthology.org/venues/naacl/). The venue page lists the proceedings volumes year by year; volumes vary by year and can include main conference, short papers, system demonstrations, student research workshop, tutorials and industry track. Adding up the volume counts shown on the venue page (checked 2026-11-07) gives the following numbers of papers per listed year.
| Year | Papers listed |
|---|---|
| 2015 | 243 |
| 2016 | 228 |
| 2018 | 409 |
| 2019 | 505 |
| 2021 | 565 |
| 2022 | 543 |
| 2024 | 668 |
| 2025 | 909 |
These are published-paper counts across all listed volumes, not submission counts, and they are not acceptance rates.
What is the acceptance rate for the NAACL conference?
The chapter site and the Anthology venue page do not publish an acceptance rate or submission count. Such figures, when a conference reports them, normally appear in the program chairs’ front matter of that year’s proceedings volume, so look there for the year you care about rather than relying on a number quoted elsewhere. Papers listed above are accepted papers only.
Strengths and limits
- Strength: open, durable record. Every listed volume is searchable in the ACL Anthology.
- Strength: a shared review route. ARR lets a paper be reviewed once and then committed to a venue, rather than reviewed from scratch for each.
- Limit: acceptance statistics are not published on the chapter or Anthology pages (see above).
- Limit: deadlines and tracks change each year; the table above describes 2027 only.
- Limit: counts above mix volume types, so year-to-year comparison is only a rough indicator of venue size.
What is the impact factor of the Computational Linguistics journal?
NAACL is a conference, and conferences do not have journal impact factors. Computational Linguistics is a separate ACL journal; a journal’s impact factor is published by Clarivate’s Journal Citation Reports, not by ACL, and this page does not quote one.
Alternatives: other ACL-family venues
| Venue | Relationship to NAACL |
|---|---|
| ACL (annual meeting) | The parent society’s own conference; uses ARR |
| EMNLP | ACL-family conference; uses ARR |
| EACL | The European chapter’s conference; uses ARR |
Per ARR’s published description, these venues share the same submission and review pipeline, so a paper reviewed in ARR can be committed to whichever suits the timing and scope.
