Dataset Details
Dataset Description
This dataset contains the CoNLL-based Extended Czech Named Entity Corpus 2.0 (CNEC 2.0_extended). The dataset is a collection of Czech texts annotated with named entities. The original CNEC 2.0 dataset contains 8993 Czech sentences with 35220 Czech named entities (train + validation + test). The original corpus uses 58 entity types. The extended version uses only 7 entity types and one additional type for non-entities:
- 'O' = Outside of a named entity
- 'B-A' = Beginning of a complex address number (Postal code, street number, even phone number)
- 'I-A' = Inside of a number in the address
- 'B-G' = Beginning of a geographical name
- 'I-G' = Inside of a geographical name
- 'B-I' = Beginning of an institution name
- 'I-I' = Inside of an institution name
- 'B-M' = Beginning of a media name (email, server, website, tv series, etc.)
- 'I-M' = Inside of a media name
- 'B-O' = Beginning of an artifact name (book, old movies, etc.)
- 'I-O' = Inside of an artifact name
- 'B-P' = Beginning of a person's name
- 'I-P' = Inside of a person's name
- 'B-T' = Beginning of a time expression
