COVID-19 Safety at AACL-IJCNLP 2022


It is the policy of ACL conferences that attendees wear high-quality, well-fitting masks while attending indoor functions at ACL events, removing their masks only the minimal amount necessary to eat and drink. This policy is in force even if local regulations are less strict, but may be superseded by stricter local regulations.


Furthermore, the ACL strongly encourages attendees to be cautious with masking in indoor space outside the conference venue (e.g. on public transit or while eating away from the venue) to avoid bringing COVID to the venue. This policy will be revisited annually by the ACL exec so as to be responsive to changing pandemic conditions.


For questions or concerns, or to report illness, please contact Kuan-Yu Chen at kychen@mail.ntust.edu.tw.

Local regulations

The Taiwan government allows the entry of vaccinated and unvaccinated travellers. But international travellers must comply with two COVID rules:

  • Take a PCR test a maximum of 48 hours before their arrival. All travellers will also be PCR tested on arrival at the airport.

  • Go through the mandatory quarantine period of 3 days, followed by a 4 day self-initiated epidemic prevention period (previously called self-health management).

The up-to-date information can be found here.

Staying safe while attending AACL-IJCNLP 2022 in person

At the conference

To ensure everyone’s safety, and with the purpose of making everyone comfortable at the conference, please carefully consider the following if you are attending in person:

  • It is the policy of ACL conferences that attendees wear high-quality, well-fitting masks while attending indoor functions at ACL events, removing their masks only the minimal amount necessary to eat and drink. We strongly encourage you to bring your own mask while at the NTUH International Convention Center (ICC), but a small number of masks will also be available at the venue.

  • The ACL strongly encourages attendees to be cautious with masking in indoor space outside the conference venue (e.g., on public transit or while eating away from the venue) to avoid bringing COVID to the venue.

  • If you start to feel ill or test positive during the conference, please leave the conference venue immediately, and do not come to the venue anymore.

  • Regular handwashing is strongly encouraged and there are also hand sanitising stations around the NTUH ICC.

  • To avoid crowded situations, we recommend making optimal use of the available spaces, particularly during coffee breaks.

  • Speakers and session chairs are not required to wear masks while presenting, as there is enough distance between speakers and audience.

  • A small number of masks and lateral flow device tests are available at the registration desk, but please be prepared and bring your own to Taipei.

We come from different countries and different personal experiences about COVID-19, and for many of us AACL-IJCNLP 2022 is the first hybrid conference after the peaks of the pandemic. In order to favour interpersonal relations, we will use a “traffic light system” with stickers to attach to your badge to indicate your feelings on social distancing:

  • Red: keep a distance

  • Amber: being cautious, no touching

  • Green: handshakes and hugs ok

Plan ahead to return home

Please ensure you know the COVID-19 testing requirements for return travel back into your country of origin. The requirements are available on your Government website.

If you need a PCR test to travel home, you can book one here.
