IARM: Inter-Aspect Relation Modeling with Memory Networks in Aspect-Based Sentiment Analysis. Navonil Majumder, Soujanya Poria, Alexander Gelbukh, Md. Shad Akhtar, Erik Cambria, Asif Ekbal. EMNLP 2018

This method attempts to model the relationship among the different aspect-terms in a sentence using memory networks to enable better sentiment classification of the aspects.

Requirements

• Python 2.7
• PyTorch 0.3
• Keras 1.0

Execution

Execute the file ABSA-emb-gpu-final-newarch3.py for training and testing on SemEval 2014 ABSA dataset. The following are the command-line arguments:

• --no-cuda: GPU is not used
• --lr: set learning rate
• --l2: set L2-norm weight
• --batch-size: set batch size
• --epochs: set number of epochs
• --hops: set number hops of memory network
• --hidden-size: set hidden representation size
• --output-size: set output representation size
• --dropout-p: set dropout probability
• --dropout-lstm: set recurrent dropout probability
• --dataset: set which dataset to use - Restaurants or Laptop

Example:

python ABSA-emb-gpu-final-newarch3.py --lr 0.001 --l2 0.0001 --dataset Laptop --hops 3 --epochs 30 --hidden-size 400 --output-size 300 --dropout-p 0.1 --dropout-lstm 0.2
