# Dataset card for coref149

### Usage
```
import datasets
data = datasets.load_dataset("cjvt/coref149", trust_remote_code=True)
```

### Dataset Summary
The dataset contains a subset of the ssj500k corpus, specifically paragraphs, annotated for coreference.
For more details please check the paper (in Slovenian) or the Clarin repository from which this dataset is being loaded.

### Supported Tasks and Leaderboards
Coreference resolution.

### Languages
Slovenian.

        ...
    ]
}
```

### Data Fields

- `id_doc`: a string ID of the document (corresponds to file name in this case);  
- `words`: a list of lists of strings containing paragraph words;  
- `mentions`: a list of dicts for each mention. Each mention contains an ID (`id_mention`) and 
positions of words inside mention (determined by `idx_sent`, `word_indices`; 
or equivalently `global_word_indices` if sentences are flattened into a single list)
- `coref_clusters`: a list of lists of strings containing mention IDs contained inside each coreference cluster.
