Abstract

Knowledge graph embeddings are supervised learning models that learn vector representations of nodes and edges of labeled, directed multigraphs. We describe their design rationale, and explain why they are receiving growing attention within the burgeoning graph representation learning community. We highlight their limitations, open research directions, and real-world applicative scenarios. Besides a theoretical overview, we also provide a hands-on session, where we show how to use such models in practice.

Goal

The goal of the tutorial is to provide answers to the following questions:

Outline

[Slides available soon]

Target Audience

The target audience is the general ECAI audience who is interested in knowledge representation and reasoning, machine learning, and natural language processing.

That includes artificial intelligence scientists, engineers, and students familiar with neural networks fundamentals and eager to know insights of graph representation learning for knowledge graphs. Researchers from graph-based knowledge representation (e.g. Semantic Web, Linked Data) and NLP also qualify as target audience.

The tutorial is of interest for either academic research and industry practitioners.

Other Details

Format: Standard (Half-day)

Presentation Style: Slide deck presentation and Jupyter notebook/Colab tutorials for the hands-on session.
