Abstract
Information extraction (IE) holds the promise
of generating a large-scale knowledge
base from the Web's natural language text.
Knowledge-based weak supervision, using
structured data to heuristically label a training
corpus, works towards this goal by enabling
the automated learning of a potentially
unbounded number of relation extractors.
Recently, researchers have developed multi-
instance learning algorithms to combat the
noisy training data that can come from
heuristic labeling, but their models assume
