Title: Knowledge Graph Evolution and Maintenance

Speaker: Héctor Pérez Urbina, Ontologist, Knowledge Engine Team, Google

Abstract

Knowledge graphs are typically not static; the data they contain might change, different representations might be necessary, the scope of the graph might expand, etc. In this talk, I'll go through some some challenges related to KG evolution and maintenance.

Héctor is part of the Knowledge Engine team at Google. His work focuses on maintaining and improving the Knowledge Graph—Google's massive knowledge base used to enhance search results with semantic-search information.
