Task-Oriented GNNs Training on Large Knowledge Graphs for Accurate and Efficient Modeling

1 code implementation9 Mar 2024 Hussein Abdallah, Waleed Afandi, Panos Kalnis, Essam Mansour

We refer to this subgraph as a task-oriented subgraph (TOSG), which contains a subset of task-related node and edge types in G. Training the task using TOSG instead of G alleviates the excessive computation required for a large KG.

Towards a GML-Enabled Knowledge Graph Platform

1 code implementation3 Mar 2023 Hussein Abdallah, Essam Mansour

While training a GML model on KG, KGNet collects metadata of trained models in the form of an RDF graph called KGMeta, which is interlinked with the relevant subgraphs in KG.

KGLiDS: A Platform for Semantic Abstraction, Linking, and Automation of Data Science

1 code implementation3 Mar 2023 Mossad Helali, Niki Monjazeb, Shubham Vashisth, Philippe Carrier, Ahmed Helal, Antonio Cavalcante, Khaled Ammar, Katja Hose, Essam Mansour

Hence, this paper presents a scalable platform, KGLiDS, that employs machine learning and knowledge graph technologies to abstract and capture the semantics of data science artifacts and their connections.

AutoML Knowledge Graphs

A Universal Question-Answering Platform for Knowledge Graphs

1 code implementation1 Mar 2023 Reham Omar, Ishika Dhall, Panos Kalnis, Essam Mansour

Knowledge from diverse application domains is organized as knowledge graphs (KGs) that are stored in RDF engines accessible in the web via SPARQL endpoints.

ChatGPT versus Traditional Question Answering for Knowledge Graphs: Current Status and Future Directions Towards Knowledge Graph Chatbots

no code implementations8 Feb 2023 Reham Omar, Omij Mangukiya, Panos Kalnis, Essam Mansour

Conversational AI and Question-Answering systems (QASs) for knowledge graphs (KGs) are both emerging research areas: they empower users with natural language interfaces for extracting information easily and effectively.

Federated Data Science to Break Down Silos [Vision]

no code implementations25 Nov 2021 Essam Mansour, Kavitha Srinivas, Katja Hose

Similar to Open Data initiatives, data science as a community has launched initiatives for sharing not only data but entire pipelines, derivatives, artifacts, etc.

A Scalable AutoML Approach Based on Graph Neural Networks

1 code implementation29 Oct 2021 Mossad Helali, Essam Mansour, Ibrahim Abdelaziz, Julian Dolby, Kavitha Srinivas

AutoML systems build machine learning models automatically by performing a search over valid data transformations and learners, along with hyper-parameter optimization for each learner.
