Title

Knowledge Graphs: Theory, Applications and Challenges

Abstract

Knowledge Graphs have rapidly become a mainstream technology that combines features of databases and AI. In this talk I will introduce Knowledge Graphs, explaining their features and the theory behind them. I will then consider some of the challenges inherent in both the theory and implementation of Knowledge Graphs and present some solutions that have made possible the development of popular language standards and robust and high-performance Knowledge Graph systems. Finally, I will illustrate the wide applicability of knowledge graph technology with example use cases including configuration management, fraud detection, semantic search & browse, and data wrangling.

Ian Horrocks is a full professor in the Oxford University Department of Computer Science, a visiting professor in the Department of Informatics at the University of Oslo and a co-founder of Oxford Semantic Technologies. His research concerns the representation of knowledge, and the efficient manipulation of such knowledge by computers. He was an author of the OIL, DAML+OIL, and OWL ontology language standards, chaired the W3C working group that standardised OWL 2, and developed many of the algorithms, optimisation techniques and reasoning systems that underpin OWL applications. He has contributed to the development of several widely used reasoning systems including FaCT++, HermiT, Elk and RDFox.

He is a Fellow of the Royal Society, a member of Academia Europaea, a Fellow of the European Association for Artificial Intelligence, a Fellow of the Alan Turing Institute, a Fellow of the British Computer Society and a British Computer Society Lovelace Medalist.

Title

Research at the Service of Free Knowledge

Abstract

With roughly 20 billion monthly pageviews, 15 million monthly edits, and almost 55 million articles across 300+ languages, Wikipedia has become a canonical part of the Free Knowledge ecosystem: enabling people to have access to knowledge and empowering them to participate in the discourse of gathering and sharing the sum of all human knowledge. By 2030, the Wikimedia projects, which include Wikipedia, aspire to break down the social, political, and technical barriers preventing people from accessing and contributing to free knowledge. In this presentation, I will talk about research in this direction. In particular, I will present our approach and research on identifying, measuring, and bridging Wikipedia's knowledge gaps. I will share some of our success stories, as well as a few of the biggest challenges we face today. I close by sharing some of the open research questions and directions.
