Logic-Scaffolding: Personalized Aspect-Instructed Recommendation Explanation Generation using LLMs

Rahdari, Behnam, Ding, Hao, Fan, Ziwei et al.

Understand

The unique capabilities of Large Language Models (LLMs), such as the natural language text generation ability, position them as strong candidates for providing explanation for recommendations.

  • However, despite the size of the LLM, most existing models struggle to produce zero-shot explanations reliably.
  • To address this issue, we propose a framework called Logic-Scaffolding, that combines the ideas of aspect-based explanation and chain-of-thought prompting to generate explanations through intermediate reasoning steps.
  • In this paper, we share our experience in building the framework and present an interactive demonstration for exploring our results.
