MonaLog: a Lightweight System for Natural Language Inference Based on Monotonicity

Authors: , , , , ,

Abstract

We present a new logic-based inference engine for natural language inference called MonaLog, which is based on the monotonicity calculus and natural logic. In contrast to existing logic-based approaches, our system is lightweight, and operates using a small set of well-known monotonicity facts about quantifiers and lexical items. Despite its simplicity, we find it competitive with other logic-based NLI models on the SICK benchmark. We also use MonaLog incombination with BERT in a variety of settings, including data augmentation. We show that MonaLog is capable of generating large amounts of high-quality training data for BERT, improving its accuracy on SICK.
