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 task aims at recognizing mentions of named entities in news articles in Slavic languages,
their lemmatization, and cross-language matching.


The 2019 edition of the shared task covers four languages:
* Bulgarian,
* Czech,
* Polish,
* Russian.

and focuses on recognition of five types of named entities including:
* persons,
* locations,
* organizations,
* events,
* products.


The detailed task description and system response guidelines are available at 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.


Registration

Teams that plan to participate should register via sending an email to: bsnlp@cs.helsinki.fi
which includes the following information:
* team name,
* team composition,
* contact person,
* contact email.

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


Publication

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.
