As with our previous meeting in Santa Fe in 2018, COLING'2020 will allow for remote presentations in special circumstances where the authors are unable to attend the conference in person.

We have been constantly monitoring the developments with regard to COVID-19. In response to the pandemic, we have already postponed the date of the conference from September to December and adjusted the submission deadlines accordingly. While we are still forging ahead with our plans for an in-person conference in Barcelona in December, we are aware that the situation may well not improve in the coming months. For this reason, we are also making parallel contingency plans for a fully virtual conference if necessary.

The idea behind the anonymity period is to guarantee blind review, that is, that reviewers cannot find the same paper with a visible author and multiple comments on twitter so that they could get biased. Because arxiv can spend one or two days to publish a submission, the date is set as submission date, but the general idea is that after June, 1st there cannot be a copy of your paper with your name published. In case that eventually this happens, you must communicate at submission time as information in the title page (see submission page for guidelines).

Yes, it is possible to submit appendices. Please, note that appendices must be materials that are not critical to the reading and understanding of the paper. Appendices can contain code, a dataset, additional tables or parameters and data required for reproducibility. Appendices can be uploaded as supplementary material when submitting the paper for review or provided with an anonymized link to a direct download (ensure that author and institution names are not present in the URL if attaching this way). Upon acceptance, the appendices come after the reference.

The panot de flor, also called Flower of Barcelona, is a type of tile designed by Josep Puig i Cadafalch. Originaly designed for Ametller house, it was later used to pave many streets of Barcelona, specially in the Eixample district. Although it may go unnoticed by many, it is one of the most representative symbols of the city.
