# Dataset Information
This dataset is designed for the **Dependency parsing task** and is used to train the Airudit multitask model.
## Dataset Description
The dataset combines **Universal Dependencies v2.17** French corpora available at
[commul/universal_dependencies](https://huggingface.co/datasets/commul/universal_dependencies).
Included corpora:
- commul/universal_dependencies/fr_gsd
- commul/universal_dependencies/fr_sequoia
- commul/universal_dependencies/fr_rhapsodie
Nb. Other corpora, as 'fr_parisstories', 'fr_partut', 'fr_poitevindivital', 'fr_pud' are excluded because of too large difference in labels sets.
## Dataset Structure
The dataset contains the following splits:
```
DatasetDict({
train: Dataset({
features: ['sent_id', 'tokens', 'head', 'deprel'],
num_rows: 17925
})
dev: Dataset({
features: ['sent_id', 'tokens', 'head', 'deprel'],
num_rows: 2950
})
test_fr_gsd: Dataset({
features: ['sent_id', 'tokens', 'head', 'deprel'],
num_rows: 415
})
test_fr_rhapsodie: Dataset({
features: ['sent_id', 'tokens', 'head', 'deprel'],
num_rows: 812
})
test_fr_sequoia: Dataset({
features: ['sent_id', 'tokens', 'head', 'deprel'],
num_rows: 456
})
})
```
## Labels
Labels are encoded in the dataset and can be retrieved as following :
```python
from datasets import load_dataset
ds = load_dataset('airudit/UD_v2_17_DEP')
ds["train"].features["deprel"].feature.names
# ['acl', 'acl:relcl', 'advcl', 'advcl:cleft', 'advmod', 'amod', 'appos', 'aux', 'aux:caus', 'aux:pass', 'aux:tense', 'case', 'cc', 'ccomp', 'compound', 'conj', 'cop', 'csubj', 'csubj:pass', 'dep', 'dep:comp', 'det', 'discourse', 'dislocated', 'expl:comp', 'expl:pass', 'expl:subj', 'fixed', 'flat:foreign', 'flat:name', 'iobj', 'mark', 'nmod', 'nsubj', 'nsubj:caus', 'nsubj:outer', 'nsubj:pass', 'nummod', 'obj', 'obj:lvc', 'obl', 'obl:agent', 'obl:arg', 'obl:mod', 'orphan', 'parataxis', 'parataxis:insert', 'punct', 'reparandum', 'root', 'vocative', 'xcomp']
```
## 🔍 Quick usage example:
```python
from datasets import load_dataset
ds = load_dataset('airudit/UD_v2_17_DEP')
ds["train"][0]
# {'sent_id': [...], 'tokens': [...], 'head': [...], 'deprel': [...]}
```
## 📦 Dataset Pre-Processing :
### Dependency Relation Filtering :
Sentences containing the following dependency relations are removed:
- [flat](https://universaldependencies.org/treebanks/fr_gsd/fr_gsd-dep-flat.html) This relation does not appear in **Sequoia** treebank beacause the annotation always uses a subtype (e.g. `flat:name`).
When `flat` is not subtyped it is difficult to automatically map it to a consistent subype.
- [parataxis:parenth](https://universaldependencies.org/fr/dep/parataxis-parenth.html) is used to annotate parenthetical clauses.
Only present in **Rhapsodie** treebank.
The number of occurrences is small (39 occ), and parentical are currently not cosidered essential for target multitask model.
In total, removed **14** sentences for **GSD** treebank and **78** sentences for **Rhapsodie** treebank.
### Dependency Relation Normalization :
To harmonize the annotation schemes across treebanks, the following mapping is applied:
```
{
"goeswith": "compound",
"expl:pv": "expl:pass",
"obj:agent": "obj",
"iobj:agent": "iobj",
"nmod:appos": "nmod"
}
```
Occurrences affected by this normalization:
```
fr_gsd
{'expl:pv': 1016, 'obj:agent': 111, 'goeswith': 38, 'iobj:agent': 24}
fr_rhapsodie
{'nmod:appos': 115}
fr_sequoia
{'expl:pv': 242, 'obj:agent': 12, 'goeswith': 2, 'iobj:agent': 1}
```
### Additional Label
The relation [reparandum](https://universaldependencies.org/treebanks/fr_rhapsodie/fr_rhapsodie-dep-reparandum.html) is added to the final vocabulary.
- The label appears only in **Rhapsodie** treebank (1205 occ).
- It is used to annotate speech disfluencies and self-corrections.
- This information can be useful for ASR post-processing tasks.
### Structure
- Train and dev splits from all corpora are merged into unified train and dev splits.
- Test splits are preserved and renamed according to their source corpus.
- Only the relevant columns are kept: ["sent_id", "tokens", "head", "deprel"].
- The dataset was generated using the following script: multitask-nlp/src/multitask_nlp/datasets/dependency_dataset_preparation.py
