SeqCSG

This repository contains code for:

• Target-oriented Sentiment Classification with Sequential Cross-modal Semantic Graph

Model Architecture

Dependencies

• Python 3
• PyTorch >= 1.7.1
• Transformers>= 4.19.2
• NumPy
• All experiments are performed with one RTX 3090Ti GPU.

Prerequisites

• DATASET: Download the Twitter2015 and Twitter2017 dataset followed instructions in the TomBERT repo, and place them in ./data/.
• Cache: We use Scene-Graph-Benchmark to parse scene graphs from the images, then place imageid2triple.json and sub_images in ./cache/.

Code Structures

There are four parts in the code.

• model: It contains the main files for SeqCSG network.
• data: It contains the data splits for different datasets.
• cache: It contains some cache files.
• script: The training scripts for SeqCSG.

Train & Eval

The training script for Twitter2015:

bash scripts/run_2015.sh

Parameter

[--dataset {twitter2015, twitter2017}] [--EPOCHS epoch] [--BATCH_SIZE batch_size] [--RANDOM_SEEDS seeds]
[--LEARNING_RATE learning_rate] [--image_feature image_encoder] [--triple_number numbers]

Note:

• you can open the .sh file for parameter modification.
