This is an Answer Set Programming (ASP) encoding for LACE+, which is a novel declarative approach to Collective Entity Resolution in the classical relational database setting, capable of performing both global and local merges. With such an approach, users can specify hard and soft rules to specify conditions under which pairs of entity references and pairs of values must or may be merged, together with denial constraints that enforce the consistency of the resulting instance. Using this implementation, users can input their own ASP encoding with respect to an input relational database.
