The ACL Special Interest Group on Slavic NLP invites participation in the 2nd edition

of the Shared Task on Multilingual Named Entity Recognition for Slavic languages.

Results of the shared task will be presented at the BSNLP-2019 Workshop,

to be held at ACL-2019 [http://www.acl2019.org] in Florence, Italy, on 2 August, 2019.

The detailed task description and system response guidelines are available HERE <http://bsnlp.cs.helsinki.fi/Guidelines-shared-task-2019.pdf>

IMPORTANT: it is not mandatory to participate in the full-fledged version of the task,

e.g., monolingual system responses without lemmatization of the extracted named entities

will be evaluated and scored too.

Data Sets

The training data will consist of two moderate-size sets of annotated documents,

each related to a specific topic (Brexit and Asia Bibi), whereas the test dataset

will consist of two other sets of raw documents, each also related to a specific topic,

which will be different from the topics in the training data set.

Registered participants will receive the full annotated corpora and further information via email.


Teams that plan to participate should register via sending an email to: bsnlp at cs.helsinki.fi

which includes the following information:


team name,


team composition,

The registered teams will receive access to data and additional information related to the shared task.


Participants in the shared task are invited to submit a short paper to the BSNLP 2019 workshop (http://bsnlp.cs.helsinki.fi/),

although submitting a paper is not mandatory to participate in the shared task.

All accepted shared task papers will appear in the Proceedings of BSNLP 2019 workshop.
