Description

Last year, Ihab Ilyas covered two primary challenges in applying machine learning to data curation: entity consolidation and using probabilistic inference to suggest data repair for identified errors and anomalies. This year, he explores these limitations in greater detail and explains why data unification projects common to modern enterprises quickly require human-guided machine learning and a probabilistic model.

Machine learning is being used to address a host of data curation challenges but must be applied in the proper context to meet the scale of the problems at hand. Using machine learning to replicate traditional techniques will fail as data sources and volume expand, regardless of the speed ML affords. Data semantics and domain-specific knowledge must be integral to the solution.

Join in to learn how to provide sufficient accuracy and scalability in building data curation and gain deeper insight into why entity consolidation and data repair problems require machine learning, human expertise, and problem semantics to deliver a scalable, high-accuracy solution.
