Note

Aspect term sentiment analysis

BERT LSTM based baseline, based on https://github.com/avinashsai/BERT-Aspect BERT LSTM implementation.The model trained on SemEval2014-Task 4 laptop and restaurant datasets.

Usage

from transformers import AutoTokenizer, AutoModelForSequenceClassification, TextClassificationPipeline

MODEL = "tezign/BERT-LSTM-based-ABSA"

tokenizer = AutoTokenizer.from_pretrained(MODEL)

model = AutoModelForSequenceClassification.from_pretrained(MODEL, trust_remote_code=True)

classifier = TextClassificationPipeline(model=model, tokenizer=tokenizer)

result = classifier([
    {"text": "The appearance is very nice, but the battery life is poor", "text_pair": "appearance"},
    {"text": "The appearance is very nice, but the battery life is poor", "text_pair": "battery"}
],
    function_to_apply="softmax")

print(result)
