Speaker: Renzo Angles, Department of Computer Science, Universidad de Talca, Chile.

Title:  “Harnessing the Knowledge: Languages and Models underlying Knowledge Graphs”


A knowledge graph is a large database that integrates information from different data sources with the aim of generating additional information and knowledge. This database is represented by a graph.  Thus, the entities are represented by nodes, and the relationships among these entities are represented by edges. The purpose of this presentation is to review the data models used to represent knowledge graphs, the query languages that allow extracting information and the deductive and inductive methods that allow  generating knowledge.


Renzo Angles received a degree of Bachelor in Systems Engineering from Universidad Católica de Santa María (Arequipa, Perú), and a Ph.D. degree in Computer Science from Universidad de Chile. He is professor at the Universidad de Talca (Chile) since 2009, and currently is Director of the Department of Computer Science. He is also a researcher in the Millenium Institute for Foundational Research on Data (Chile). His research interests dwell in the intersection of graph databases and the Semantic Web. Specifically, he is currently working on the theory and design of graph query languages, benchmarking of graph/RDF databases, and analysis of proteins using graph technologies.
