Apart from the paper, there are two new features in PyABSA: Aspect sentiment triplet extraction and Aspect quadruple extraction. We have deployed the demos on Huggingface Space, you can try them online.

• Aspect sentiment quadruple extraction (English) New feature
• Aspect sentiment triplet extraction (English) New feature
• (Gradio) Aspect term extraction & sentiment classification ( English, Chinese, Arabic, Dutch, French, Russian, Spanish, Turkish, etc.)

Quick-Start

Extract aspect terms and classify sentiments

from pyabsa import AspectTermExtraction as ATEPC, available_checkpoints

# you can view all available checkpoints by calling available_checkpoints()
checkpoint_map = available_checkpoints()

aspect_extractor = ATEPC.AspectExtractor('multilingual',
                                         auto_device=True,  # False means load model on CPU
                                         cal_perplexity=True,
                                         )

# instance inference
aspect_extractor.predict(['I love this movie, it is so great!'],
                         save_result=True,
                         print_result=True,  # print the result
                         ignore_error=True,  # ignore the error when the model cannot predict the input
                         )

inference_source = ATEPC.ATEPCDatasetList.Restaurant16
atepc_result = aspect_extractor.batch_predict(target_file=inference_source,  #
                                              save_result=True,
                                              print_result=True,  # print the result
                                              pred_sentiment=True,  # Predict the sentiment of extracted aspect terms
                                              )

print(atepc_result)

Aspect-based sentiment analysis

from pyabsa import AspectPolarityClassification as APC, available_checkpoints

# you can view all available checkpoints by calling available_checkpoints()
checkpoint_map = available_checkpoints(show_ckpts=True)

classifier = APC.SentimentClassifier('multilingual',
                                     auto_device=True,  # False means load model on CPU
                                     cal_perplexity=True,
                                     )

# instance inference
classifier.predict(['I love this movie, it is so great!'],
                   save_result=True,
                   print_result=True,  # print the result
                   ignore_error=True,  # ignore the error when the model cannot predict the input
                   )

inference_source = APC.APCDatasetList.Laptop14
apc_result = classifier.batch_predict(target_file=inference_source,  #
                                      save_result=True,
                                      print_result=True,  # print the result
                                      pred_sentiment=True,  # Predict the sentiment of extracted aspect terms
                                      )

print(apc_result)

Notice

This repository is based on our papers for ABSA research. Here are the papers that you can cite or refer to for your implementations:

Aspect sentiment polarity classification models

1. Back to Reality: Leveraging Pattern-driven Modeling to Enable Affordable Sentiment Dependency Learning ( e.g., Fast-LSA, 2020)
2. Learning for target-dependent sentiment based on local context-aware embedding ( e.g., LCA-Net, 2020)
3. LCF: A Local Context Focus Mechanism for Aspect-Based Sentiment Classification ( e.g., LCF-BERT, 2019)

Aspect sentiment polarity classification & Aspect term extraction models

1. A multi-task learning model for Chinese-oriented aspect polarity classification and aspect term extraction] ( e.g., Fast-LCF-ATEPC, 2020)
2. (Arxiv) A multi-task learning model for Chinese-oriented aspect polarity classification and aspect term extraction

If you are looking for the original proposal of local context focus, here are some introduction at here.
