Philosophers are Mortal: Inferring the Truth of Unseen Facts
Gabor Angeli, Christopher D. Manning · 2013
Large databases of facts are prevalent in many applications. Such databases are accurate, but as they broaden their scope they become increasingly incomplete. In contrast to extending such a database, we present a system to query whether it con-tains an arbitrary fact. This work can be thought of as re-casting open domain in-formation extraction: rather than growing a database of known facts, we smooth this data into a database in which any possi-ble fact has membership with some confi-dence. We evaluate our system predicting held out facts, achieving 74.2 % accuracy and outperforming multiple baselines. We also evaluate the system as a common-sense filter for the ReVerb Open IE sys-tem, and as a method for answer validation in a Question Answering task.
