To overcome the noise in distantly-labeled examples, (Riedel et al., 2010) introduced an "at least one" heuristic, where instead of taking all mentions for a pair as correct examples only at least one of them is assumed to express that relation. MultiR<cite> (Hoffmann et al., 2011) and</cite> MIML-RE (Surdeanu et al., 2012) extend this approach to support multi- ple relations expressed by different sentences in a bag.
