WebOct 21, 2024 · In order to automatically obtain labeled training data, distant supervision is adopted in relation extraction [8]. It assumes that if two entities have a relation in knowledge base, then all sentences containing these two entities express this relation. For example, 〈 Obama, BornIn, UnitedStates 〉 is a relational fact in knowledge base. Webdistant supervision methods, the sampling process inevitably introduces bias and variance.
