TASK DESCRIPTION:

The 4thSlav-NER Shared Task focuses on Named Entities in Slavic languages.

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

The 4thSlav-NER Shared Task covers three languages:

*

Czech,

*

Polish,

*

Russian.

and five types of named entities:

*

persons,

*

locations,

*

organizations,

*

events,

*

products.

For information about training and test data, guidelines, and participation, please see the Shared Task Home Page. http://bsnlp.cs.helsinki.fi/shared-task.html

IMPORTANT: Participants are NOT required to perform all tasks or for all languages.  For example, a monolingual entry, without lemmatization of the names, can participate.

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