Text-Relational Graph Neural Networks (Text-RGNNs) for Text Classification

This repository contains the implementation of Text-Relational Graph Neural Networks (Text-RGNNs) presented in the paper Text-RGNNs: Relational Modeling for Heterogeneous Text Graphs published in IEEE Signal Processing Letters. The model leverages heterogeneous graph neural networks to capture complex relationships in text data, significantly improving performance on benchmark datasets.
