Automatic Extraction of Commonsense LocatedNear Knowledge
LocatedNear relation is a kind of commonsense knowledge describing two
physical objects that are typically found near each other in real life. In this
paper, we study how to automatically extract such relationship through a
sentence-level relation classifier and aggregating the scores of entity pairs
from a large corpus. Also, we release two benchmark datasets for evaluation and
future research.Comment: Accepted by ACL 2018. A preliminary version is presented on

Knowledge-Driven Distractor Generation for Cloze-style Multiple Choice Questions
In this paper, we propose a novel configurable framework to automatically
generate distractive choices for open-domain cloze-style multiple-choice
questions, which incorporates a general-purpose knowledge base to effectively
create a small distractor candidate set, and a feature-rich learning-to-rank
model to select distractors that are both plausible and reliable. Experimental
results on datasets across four domains show that our framework yields
distractors that are more plausible and reliable than previous methods. This
dataset can also be used as a benchmark for distractor generation in the
future.Comment: To appear at AAAI 202
