Ana Ozaki: Knowledge Graphs: Facts and Figures

Abstract

In this talk, Ana Ozaki will give an introduction to knowledge graphs, starting with the basics: What are knowledge graphs, how are they created, and what are they used for? Then, Ozaki will focus on special cases; in particular, the knowledge graphs of the Wikidata, DBpedia, and YAGO projects.

Ozaki will discuss the main reasoning tasks and how to enhance reasoning using common types of meta-knowledge present in knowledge graphs; in particular,  temporal validity and provenance. Then she will present important challenges for the maintenance of knowledge graphs, and modern approaches to deal with them.
