The Insight Visitor Programme is an initiative that brings globally-recognised researchers in data science and AI to visit Insight for several days to explore collaboration opportunities.
A core feature of the visit is a public lecture on Data Science and AI (register here)
The first lecture in the series; ‘Knowledge Graphs. A Mainstream Technology that Few Know About’; will take place on Tuesday 21st January 2025, at 2pm.
The lecture comes from Aidan Hogan, Associate Professor and Director of the Department of Computer Science, University of Chile, and an Associate Researcher and Subdirector of the Millennium Institute for Foundational Research on Data (IMFD).
Knowledge Graphs: A Mainstream Technology that Few Know About
Even if you have never heard of a Knowledge Graph, it is likely you have interacted with one (or more) of them already. Knowledge Graphs are used to power and enrich a variety of well-known applications offered by companies like AirBnB, Amazon, eBay, Facebook, Google, IBM, LinkedIn, Microsoft and Uber. Some Knowledge Graphs are available to the public, while others are closed and internal to a particular enterprise. Knowledge Graphs, in essence, integrate diverse sources of data at large scale. Within such scenarios, Knowledge Graphs have popularised the idea of modelling data following a graph-based abstraction, where nodes represent entities and edges represent the relations between entities. In terms of research, Knowledge Graphs have become a novel point of convergence for different communities, wherein a variety of techniques for creating, enriching, validating and analysing such graphs have been proposed, alongside techniques for querying, reasoning and generating machine learning models over them. In terms of practice, Knowledge Graphs are now used in diverse application scenarios involving personalised agents, recommendations, classification and prediction, semantic search, information extraction, drug discovery and fraud detection.
In this lecture, experts will provide an introduction to Knowledge Graphs, covering the fundamentals of how they are modelled, the techniques that they enable, the research questions that they raise, the applications in which they have been used and what has made them a mainstream technology (that few know about).
About the presenter:
Aidan Hogan is an Associate Professor and Director of the Department of Computer Science, University of Chile, and an Associate Researcher and Subdirector of the Millennium Institute for Foundational Research on Data (IMFD). He conducted his PhD research under the supervision of Prof. Axel Polleres at the National University of Ireland, Galway (DERI/Insight Galway), graduating in 2011. He continued as a Postdoc at DERI/Insight Galway until 2013, when he joined the University of Chile. Aidan’s research interests relate primarily to the Semantic Web, Graph Databases, Information Extraction and Reasoning; he has published over one hundred peer-reviewed works on these topics. He is an Editor-in-Chief and Co-Founder of the journal Transactions on Graph Data & Knowledge (TGDK): a recently-launched academic journal that is free for authors, and free for readers. He is the author of three books, the latest of which, ‘Knowledge Graphs’, is available online: https://kgbook.org/.
