Acknowledgment

The Code base is built upon the following work -

• RECON
• GPGNN
• SAGPOOL

Requirements

• Python 3
• torch>=1.8
• torch-geometric>=1.8

Data

We use the same dataset and the entity attributes as used by the previous baseline RECON

Usage

First, download the datasets.

Train and evaluate the model:
(make sure Glove embeddings are ready before training)

wget http://nlp.stanford.edu/data/glove.6B.zip
unzip glove.6B.zip

Train

python Context-Aggregator/train.py

Testing

python Context-Aggregator/test.py

Directory structure

Context-Aggregator/: The same folder strucutre as that of GPGNN

KGPool/data_loader.py: Data pre-processing and gathering step.

KGPool/networks.py: Set the graph architecture.

KGPool/layers.py: Perform dynamic pooling on nodes.

Hyper Parameters

• For Context-Aggregator we use the same hyper-parameters used by the baseline.
• For KGPool we use the defualt params in Context-Aggregator/train.py.
• No systematic hyper-parameter tunning was performed.
