# Turkish Treebank Benchmarking 
This is the repo for Turkish treebank benchmarking, namely evaluating Tranformer models on POS-Dep-Morph task. 
For the data, we used two treebank, [IMST](https://github.com/UniversalDependencies/UD_Turkish-IMST) and [BOUN](https://github.com/UniversalDependencies/UD_Turkish-BOUN). We converted conllu format to json lines for being compatible to HF dataset formats.

Here are treebank sizes at a glance: 

| Dataset | train lines | dev lines | test lines| 
|---|---|---|---|
| BOUN  | 7803  | 979  | 979  |
| IMST  | 3435  | 1100 | 1100  |




A typical instance from the dataset looks like:

```
{
  "id": "ins_1267",
  "tokens": [
    "Rüzgâr",
    "yine",
    "güçlü",
    "esiyor",
    "du",
    "."
  ],
  "upos": [
    "NOUN",
    "ADV",
    "ADV",
    "VERB",
    "AUX",
    "PUNCT"
  ],
  "heads": [

  "rels": [

    "advmod",
    "advmod",
    "root",
    "cop",
    "punct"
  ],
  "feats": [
    "Case=Nom|Number=Sing|Person=3",
    "_",
    "_",
    "Aspect=Imp|Polarity=Pos|VerbForm=Part",
    "Aspect=Perf|Evident=Fh|Number=Sing|Person=3|Tense=Past",
    "_"
  ],
  "text": "Rüzgâr yine güçlü esiyor du .",
  "feats_dict_json": [
    "{\"Case\":\"Nom\",\"Number\":\"Sing\",\"Person\":\"3\"}",
    "{}",
    "{}",
    "{\"Aspect\":\"Imp\",\"Polarity\":\"Pos\",\"VerbForm\":\"Part\"}",
    "{\"Aspect\":\"Perf\",\"Evident\":\"Fh\",\"Number\":\"Sing\",\"Person\":\"3\",\"Tense\":\"Past\"}",
    "{}"
  ]
}
```

## Benchmarking
Benchmarking is done by scripts on accompanying [Github repo](https://github.com/turkish-nlp-suite/Treebank-Benchmarking). Please proceed to this repo for running the experiments.
Here are the benchmarking results for BERTurk with our scripts:

| las | 0.7459 | 0.6960 |
| morph_Abbr_acc | 0.4657 | 0.6705 |
| morph_Aspect_acc | 0.1141 | 0.1152 |
| morph_Case_acc | 0.1196 | 0.0586 |

| morph_PronType_acc | 0.1535 | 0.2680 |
| morph_Reflex_acc | 0.5620 | 0.7051 |
| morph_Tense_acc | 0.2149 | 0.1241 |
| morph_Typo_acc | 0.5081 | — |
| morph_VerbForm_acc | 0.4912 | 0.2364 |
| morph_Voice_acc | 0.0201 | 0.2602 |
| morph_Polite_acc | — | 0.1436 |
| morph_micro_acc | 0.3076 | 0.2915 |

Notes:
- `—` means that metric wasn’t present in that dataset’s reported results (e.g., `morph_Typo_acc` only in BOUN; `morph_Polite_acc` only in IMST).
