# RuBERT base fine-tuned on ruDEFT and WCL Wiki Ru datasets for NER
The model aims to extract terms and defenitions in a text. 
Labels:
- Term - a word or phrase.
- Definition - the span that defines some term.

```python
import torch
import numpy as np
from transformers import AutoTokenizer, AutoModelForTokenClassification

tokenizer = AutoTokenizer.from_pretrained("psytechlab/wcl-wiki_rudeft__ner-model")
model = AutoModelForTokenClassification.from_pretrained("psytechlab/wcl-wiki_rudeft__ner-model")
model.eval()

inputs = tokenizer('оромо — это африканская этническая группа, проживающая в эфиопии и в меньшей степени в кении.', return_tensors="pt")
with torch.no_grad():
    outputs = model(**inputs)

logits = outputs.logits
predictions = torch.argmax(logits, dim=-1)[0].tolist() 

tokens = inputs["input_ids"][0]
word_ids = inputs.word_ids(batch_index=0)

word_to_labels = {}
for token_id, word_id, label_id in zip(tokens, word_ids, predictions):
    if word_id is None:
        continue
    if word_id not in word_to_labels:
        word_to_labels[word_id] = []
    word_to_labels[word_id].append(label_id)

word_level_predictions = [model.config.id2label[labels[0]] for labels in word_to_labels.values()]

print(word_level_predictions)
# ['B-Term', 'O', 'O', 'O', 'O', 'O', 'O', 'O', 'O', 'O', 'O', 'O', 'O', 'O', 'O', 'O', 'O']
```

## Training procedure

### Training
The training was done with Trainier class that has next parameters:
```python
training_args = TrainingArguments(
    eval_strategy="epoch",
    save_strategy="epoch",
    learning_rate=2e-5,
    num_train_epochs=7,
    weight_decay=0.01,
)
```
