QDA: A Query Driven Approach to Entity Resolution

QDA: A Query Driven Approach to Entity Resolution

This paper addresses the problem of query-aware data cleaning in the context of a user query. In particular, we develop a novel Query-Driven Approach (QDA) that systematically exploits the semantics of the predicates in SQL-like selection queries to reduce the data cleaning overhead. The objective of QDA is to issue the minimum number of cleaning steps that are necessary to answer a given SQL-like selection correctly. The comprehensive empirical evaluation of QDA demonstrates outstanding results – that is QDA is significantly better compared to traditional ER techniques, especially when the query is very selective.
