# Aggregated Universal Dependencies for Ancient Greek

Based on the Github r2.15 release of all Ancient Greek corpora, namely PROIEL, Perseus, PTNK. Parsed with [`conllu`](https://github.com/EmilStenstrom/conllu).

To ensure compatibility with Hugging Face datasets and the underlying Arrow format, some quirks are present in the dataset:

- the ID field (`token_ids`) is a string rather than an integer. This is needed because in rare cases the ID can be a token range like `1-2`.
- because features can contain arbitrary content that is only semi-structured (not consistent across tokens), it is dumped as a JSON string for each token. So the `token_feats` field is a list of strings where each string should be JSON-decoded before use.
- the same is true for `token_miscs`
- and also for `sent_metadata` which contains the sentence metadata apart from the text and ID

## License

Note that not all corpora have the same license. Only use those that you can comply with and filter as necessary on the `corpus` field:

- "PROIEL": "cc-by-nc-sa-4.0"
- "Perseus": "cc-by-nc-sa-2.5"
- "PTNK": "cc-by-sa-4.0"
