In this paper, we propose methods to polish representation learning for the Multimodal Review Helpfulness Prediction (MRHP) task. In particular, we advance cross-modal relation representations by learning mutual information through contrastive learning. We also propose an adaptive weighting strategy to encourage flexiblity in contrastive objective optimization. Moreover, we integrate a cross-modal interaction module to relax the model’s reliance upon the unalignment nature among modalities, further refining multimodal features. Our framework outperforms prior baselines in the MRHP problem.

Requirements

• scikit-learn
• Pillowspacy
• torch
• tabulate
• nltk
• numpy
• tqdm
• dill
• hyperopt
• pandas
• networkx
• h5py
• coverage
• codecov

How to Run

1. To prepare the multimodal datasets of Lazada-MRHP and Amazon-MRHP, we follow the guideline provided here.
2. Run the following command to execute the training procedure:

bash ./scripts/{dataset}/train_{segment}.sh

For example, bash ./scripts/amazon/train_home.sh or bash ./scripts/amazon/train_clothing.sh

Acknowledgement

Our implementation is based on the MCR code for the MRHP task.
