Incorporating Task-Specific Concept Knowledge into Script Learning
Chenkai Sun, Tie Jun Xu, ChengXiang Zhai, Heng Ji · 2023
In this paper, we present TETRIS, a new task of Goal-Oriented Script Completion.Unlike previous work, it considers a more realistic and general setting, where the input includes not only the goal but also additional user context, including preferences and history.To address this problem, we propose a novel approach, which uses two techniques to improve performance: (1) concept prompting, and (2) scriptoriented contrastive learning that addresses step repetition and hallucination problems.On our WikiHow-based dataset, we find that both methods improve performance.
