Tutorial: Uncertain Entity Resolution Re-evaluating Entity Resolution in the Big Data Era

Entity resolution is a fundamental problem in data integra-tion dealing with the combination of data from different sources to a unified view of the data. Entity resolution is inherently an uncertain process because the decision to map a set of records to the same entity cannot be made with certainty unless these are identical in all of their attributes or have a common key. In the light of recent advancement in data accumulation, management, and analytics landscape (known as big data) the tutorial re-evaluates the entity reso-lution process and in particular looks at best ways to handle data veracity. The tutorial ties entity resolution with re-cent advances in probabilistic database research, focusing on sources of uncertainty in the entity resolution process
