# Training
This model is designed for token classification tasks, enabling it to extract aspect terms and predict the sentiment polarity associated with the extracted aspect terms.
## Datasets
This model has been trained on the following datasets:
1. Aspect Based Sentiment Analysis SemEval Shared Tasks ([2014](https://aclanthology.org/S14-2004/), [2015](https://aclanthology.org/S15-2082/), [2016](https://aclanthology.org/S16-1002/))
2. Multi-Aspect Multi-Sentiment [MAMS](https://aclanthology.org/D19-1654/)
# Use
* Importing the libraries and loading the models and the pipeline
```python
from transformers import AutoTokenizer, AutoModelForTokenClassification
from transformers import pipeline
model_id = "gauneg/roberta-base-absa-ate-sentiment"
tokenizer = AutoTokenizer.from_pretrained(model_id)
model = AutoModelForTokenClassification.from_pretrained(model_id)
ate_sent_pipeline = pipeline(task='ner',
aggregation_strategy='simple',
tokenizer=tokenizer,
model=model)
```
* Using the pipeline object:
```python
text_input = "Been here a few times and food has always been good but service really suffers when it gets crowded."
ate_sent_pipeline(text_input)
```
* pipeline output:
```bash
[{'entity_group': 'pos',
'score': 0.8447307,
'word': ' food',
'start': 26,
'end': 30},
{'entity_group': 'neg',
'score': 0.81927896,
'word': ' service',
'start': 56,
'end': 63}]
```
