• Title: You Can Generate It Again: Data-to-text Generation with Verification and Correction Prompting
• Authors: Xuan Ren, Lingqiao Liu
• Abstract summary: We propose a novel approach that goes beyond traditional one-shot generation methods by introducing a multi-step process. The observations from the verification step are converted into a specialized error-indication prompt, which instructs the model to regenerate the output. This procedure enables the model to incorporate feedback from the error-indication prompt, resulting in improved output generation.

• Abstract: Despite significant advancements in existing models, generating text descriptions from structured data input, known as data-to-text generation, remains a challenging task. In this paper, we propose a novel approach that goes beyond traditional one-shot generation methods by introducing a multi-step process consisting of generation, verification, and correction stages. Our approach, VCP(Verification and Correction Prompting), begins with the model generating an initial output. We then proceed to verify the correctness of different aspects of the generated text. The observations from the verification step are converted into a specialized error-indication prompt, which instructs the model to regenerate the output while considering the identified errors. To enhance the model's correction ability, we have developed a carefully designed training procedure. This procedure enables the model to incorporate feedback from the error-indication prompt, resulting in improved output generation. Through experimental results, we demonstrate that our approach effectively reduces slot error rates while maintaining the overall quality of the generated text.

We propose two simple techniques to reduce these correlations in training sets.
