Meeting Description:

The 3rd edition of the SlavNER Shared Task focuses on the analysis of Named
Entities in multilingual Web documents in Slavic languages.

Due to rich inflection, free word order, derivation, and other phenomena
present in the the Slavic languages, work on Named Entities poses a
challenging task. Fostering research & development on the problems of Named
Entities — detecting mentions of names, lemmatization (normalization),
classification, and cross-lingual matching — is crucial for cross-lingual
information access and wider use of NLP in Slavic languages.

The 3rd edition of the shared task covers six languages:
 - Bulgarian,
 - Czech,
 - Polish,
 - Russian,
 - Slovene,
 - Ukrainian.
and five types of named entities:
 - persons,
 - locations,
 - organizations,
 - events,
 - products.

The Shared Task focuses on cross-lingual, document-level extraction of named
entities — the systems should recognize, classify, and extract all named
entity mentions in a document; detecting the position of each named entity
mention is not required. Named-entity mentions should be lemmatized, and
mentions referring to the same real-world object should be linked across
documents and languages. The input text collection consists of sets of
documents retrieved from the Web, each set being about a certain entity or
event. The corpus was obtained by crawling the Web and parsing the HTML of
documents.

IMPORTANT: it is NOT mandatory to participate in the full task, e.g.,
monolingual responses, without lemmatization of the extracted named entities,
can be evaluated also.
