Task Description
*
*The 4th Slav-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 4th Slav-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 position of 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.
