Recent Advances in Entity Matching

Speaker: An Hai Doan, University of Wisconsin at Madison

Abstract

Entity matching (EM) finds data instances that refer to the same real-world entity, such as (D. Smith, UW-Madison) and (Dave Smith, UWM). This problem is ubiquitous in data integration, and plays a fundamental role in knowledge graph construction. In this talk I will describe current advances in EM, focusing on efforts to build open-source EM platforms as well as commercial ones. In particular, I will describe the Magellan project at the University of Wisconsin-Madison, which develops the PyMatcher on-prem EM platform as well as CloudMatcher, a cloud-based EM platform. I will discuss how these EM platforms combine machine learning, big data processing, and effective user interaction to solve EM problems. Magellan has recently been commercialized by the startup GreenBay and pushed into commercial EM platforms at Informatica, the world-leading data integration company. Finally, I will touch upon how Magellan technologies are helping to build knowledge graphs at Informatica.
