A Survey of Distant Supervision Methods using PGMs
share
Relation Extraction refers to the task of populating a database with tuples of the form r(e_1, e_2), where r is a relation and e_1, e_2 are entities. Distant supervision is one such technique which tries to automatically generate training examples based on an existing KB such as Freebase. This paper is a survey of some of the techniques in distant supervision which primarily rely on Probabilistic Graphical Models (PGMs).
