Ana Ozaki: Knowledge Graphs: Facts and Figures
June 12, 2019. Tid: 14:15 - 15:30Free
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.
Ana Ozaki is an assistant professor at the Free University of Bozen-Bolzano, in Italy. She has been working on formalisms for knowledge representation and automated reasoning, and on learning models from computational learning theory. Before working in Italy, she worked as a postdoc at the Technische Universität Dresden, in Germany. She completed her Ph.D. at the University of Liverpool. Her thesis is entitled Exact Learning of Description Logic Ontologies.
