Automatic Knowledge Augmentation for Generative Commonsense Reasoning (2111.00192v1)

Abstract: Generative commonsense reasoning is the capability of a LLM to generate a sentence with a given concept-set that is based on commonsense knowledge. However, generative LLMs still struggle to provide outputs, and the training set does not contain patterns that are sufficient for generative commonsense reasoning. In this paper, we propose a data-centric method that uses automatic knowledge augmentation to extend commonsense knowledge using a machine knowledge generator. This method can generate semi-golden sentences that improve the generative commonsense reasoning of a LLM without architecture modifications. Furthermore, this approach is a model-agnostic method and does not require human effort for data construction.
