## Dataset Description

### Dataset Summary
This dataset consists of parallel sentences labeled with CONLL2003 tags, which allows use it for the evaluation of cross-lingual annotation projection methods for cross lingual named entity recognition.

### Original description

This dataset contains a gold-standard test set created from the Europarl corpus. The test set consists of 799 sentences manually annotated using four entity types and following the CoNLL 2002 and 2003 guidelines for 4 languages: English, German, Italian and Spanish.

If you use this corpus for your research, please cite the following publication:


> Rodrigo Agerri, Yiling Chung, Itziar Aldabe, Nora Aranberri, Gorka Labaka and German Rigau (2018). Building Named Entity Recognition Taggers via Parallel Corpora. In Proceedings of the 11th Language Resources and Evaluation Conference (LREC 2018), 7-12 May, 2018, Miyazaki, Japan.


You should also consider citing the original Europarl publication:

> Europarl: A Parallel Corpus for Statistical Machine Translation, Philipp Koehn, MT Summit 2005.


This evaluation corpus was manually annotated by Nora Aranberri.

### Languages
The dataset contains 4 languages, one in each of the configuration subsets:
- en - English
- de - German
- es - Spanish
- it - Italian

## Dataset Structure

### Data Instances

This is an example in the "test" split of the "en" (English language) configuration subset:
```python
{
  'tokens': ["Thank", "you", ",", "Mr", "Segni", ",", "I", "shall", "do", "so", "gladly", "."],
  'ner_tags': [0, 0, 0, 0, 1, 0, 0, 0, 0, 0, 0, 0],
}
```

### Data Fields

- `tokens`: a `list` of `string` features.
- `ner_tags`: a `list` of classification labels, with possible values including `O` (0), `B-PER` (1), `I-PER` (2), `B-ORG` (3), `I-ORG` (4), `B-LOC` (5), `I-LOC` (6), `B-MISC` (7), `I-MISC` (8),

### Data Splits

Every subset contains only a test split with 799 rows.
