Workshop at ISWC 2021 on
Deep Learning for Knowledge Graphs
More Details!

About

Over the past years there has been a rapid growth in the use and the importance of Knowledge Graphs (KGs) along with their application to many important tasks. KGs are large networks of real-world entities described in terms of their semantic types and their relationships to each other. On the other hand, Deep Learning methods have also become an important area of research, achieving some important breakthrough in various research fields, especially Natural Language Processing (NLP) and Image Recognition.

In order to pursue more advanced methodologies, it has become critical that the communities related to Deep Learning, Knowledge Graphs, and NLP join their forces in order to develop more effective algorithms and applications. This workshop, in the wake of other similar efforts at previous Semantic Web conferences such as ESWC2018 as DL4KGs and ISWC2018, ESWC2019, ESWC 2020 aims to reinforce the relationships between these communities and foster inter-disciplinary research in the areas of KG, Deep Learning, and Natural Language Processing.

Keynote Speaker



Aldo Gangemi

Title: A Cognitive Stance about Knowledge Graphs and Embeddings
Abstract: Knowledge graph embeddings, and in general what kind of entity features are represented in there, are both an opportunity and a matter of concern for the cognitive scientist. We can find interesting patterns, but we also wonder whether we are getting the thing right with respect to human-centred semantics. The talk will recap some traditional issues with model-theoretic and vectorial knowledge representation, and pose some questions to KGE research.
