The MADAR Shared Task on Arabic Fine-Grained Dialect Identification - Colocated with The 4th Arabic Natural Language Processing Workshop (WANLP 2019 <http://wanlp2019.arabic-nlp.net/>) and ACL 2019 in Florence, Italy (August 1, 2019).
Website: https://sites.google.com/view/madar-shared-task/ Registration Link: https://docs.google.com/forms/d/e/1FAIpQLSe3zUMW_gWY6oHU9QHqkxN_QRAgx3Z8kY8MCaYrrfMBlZPkzQ/viewform
Introduction Arabic dialect identification is the task of automatically labeling a segment of speech or text with the dialect it comes from. Most of previous work and shared tasks on dialect identification focused on regional level dialect labeling as in efforts by Zaidan and Callison-Burch, Elfardy and Diab, and the VarDial ADI evaluation campaign. This shared task will be the first to target a large set of dialect labels at the city and country levels. The data for the shared task is created or collected under the Multi-Arabic Dialect Applications and Resources (MADAR) project.
Shared Task There are two subtasks in this shared task.
Subtask 1: MADAR Travel Domain Dialect Identification. The data of this subtask is the same reported on in the following papers.
Bouamor, H., Habash, N., Salameh, M., Zaghouani, W., Rambow, O., et al. (2018). The MADAR Arabic Dialect Corpus and Lexicon. In Proceedings of the 11th International Conference on Language Resources and Evaluation. (PDF: http://www.lrec-conf.org/proceedings/lrec2018/pdf/351.pdf)

Subtask 2: MADAR Twitter User Dialect Identification. This is a new data set created for this shared task.
Metrics: The evaluation metrics will include precision/recall/f-score/accuracy in addition to a new hierarchical evaluation metric designed for Arabic dialects. Macro Averaged F-score will be the official metric.
Participants need to register using the registration link below. All participating teams will be provided with a common training data set and a common development set. No external manually labelled data sets are allowed. A blind test data set will be used to evaluate the output of the participating teams. An evaluation script will be also provided to all the teams. All teams are required to report on the development and test set in their write-ups.
The shared task will be hosted through CODALAB (Links TBD).
