Leveraging LLM-GNN Integration for Open-World Question Answering over Knowledge Graphs

Hussein Abdallah, Ibrahim Abdelaziz, Panos Kalnis +1

Open-world Question Answering (OW-QA) over knowledge graphs (KGs) aims to answer questions over incomplete or evolving KGs. Traditional KGQA assumes a closed world where answers mu…

Towards a GML-Enabled Knowledge Graph Platform

Hussein Abdallah, Essam Mansour

This vision paper proposes KGNet, an on-demand graph machine learning (GML) as a service on top of RDF engines to support GML-enabled SPARQL queries. KGNet automates the training o…
