Numerous previous studies have considered distant or weak supervision from a single relational database as an alternative to manual supervision for information extraction (Hoffmann et al., 2011;Weld et al., 2009;Bellare and McCallum, 2007;Bunescu and Mooney, 2007;Mintz et al., 2009;.
to these systems, our distant supervision NED system provides a meta-algorithm for generating an NED system for any database and any entity type.
