Relation Extraction Using Distant Supervision: A Survey
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. Furthermore, it is di cult to assess the performance gap from supervised learning. This motivates us to propose a new evaluation methodology by creating a simulated distant-supervision scenario from an annotated dataset, which enables us to assess … scratched in pool
