GATES: Using Graph Attention Networks for Entity Summarization

This repository contains the implementation and dataset of our paper GATES: Using Graph Attention Networks for Entity Summarization.

## Dataset

On this experiment, we used two datasets:

1. ESBM (version 1.2) that consists of 175 entities related to 150 entities from DBpedia and 25 entities from LinkedMDB.
2. FACES dataset.

Pre-trained Knowledge Graph Embedding Models

GATES implements knowledge graph embedding and also provides pre-trained model for each model on ESBM benchmark dataset as follows:

• ComplEx
• ConEx
• DistMult

Pre-trained Word Embedding Models

GATES applies Glove and fastText as word embeddings.

Glove

1. Download pre-trained model glove.6B.zip
2. Extract the zip file in data folder

fastText

1. Download pre-trained model wiki-news-300d-1M.vec.zip
2. Extract the zip file and put the file on data folder
