本文提出了一种名为PIECE的新颖规划引擎框架,通过两阶段知识封装和层束卷积学习增强LLMs在心理咨询摘要任务中的领域知识对齐能力,显著提升了多项指标并展现出良好的泛化性。

摘要:

在心理咨询中,将对话浓缩为简洁且相关的摘要(即咨询记录)具有重要意义。大型语言模型(LLMs)在各种生成任务中展现出卓越能力;然而,它们对特定领域复杂性的适应仍具挑战,尤其在心理健康语境下。与标准LLMs不同,心理健康专家在撰写摘要时首先会规划应用领域知识。我们的工作通过引入一种新颖的规划引擎来协调结构化知识对齐,从而增强了LLMs的能力。为实现高阶规划,我们将知识封装划分为两个主要阶段:持有对话结构和融入特定领域知识。我们在Llama-2上采用规划引擎,由此产生了一个新颖的框架PIECE。我们提出的系统采用知识过滤兼脚手架来封装领域知识。此外,PIECE利用层束卷积学习来增强其对对话结构细微差别的理解。我们将PIECE与14种基线方法进行比较,观察到在ROUGE和Bleurt分数上均有显著提升。此外,专家评估和分析验证了生成质量的有效性,有时甚至超越了黄金标准。我们进一步将PIECE与其他LLMs进行基准测试并报告了改进,包括Llama-2(+2.72%)、Mistral(+2.04%)和Zephyr(+1.59%),以证明规划引擎的泛化能力。

英文摘要:

In mental health counseling, condensing dialogues into concise and relevant summaries (aka counseling notes) holds pivotal significance. Large Language Models (LLMs) exhibit remarkable capabilities in various generative tasks; however, their adaptation to domain-specific intricacies remains challenging, especially within mental health contexts. Unlike standard LLMs, mental health experts first plan to apply domain knowledge in writing summaries. Our work enhances LLMs' ability by introducing a novel planning engine to orchestrate structuring knowledge alignment. To achieve high-order planning, we divide knowledge encapsulation into two major phases: (i) holding dialogue structure and (ii) incorporating domain-specific knowledge. We employ a planning engine on Llama-2, resulting in a novel framework, PIECE. Our proposed system employs knowledge filtering-cum-scaffolding to encapsulate domain knowledge. Additionally, PIECE leverages sheaf convolution learning to enhance its understanding of the dialogue's structural nuances. We compare PIECE with 14 baseline methods and observe a significant improvement across ROUGE and Bleurt scores. Further, expert evaluation and analyses validate the generation quality to be effective, sometimes even surpassing the gold standard. We further benchmark PIECE with other LLMs and report improvement, including Llama-2 (+2.72%), Mistral (+2.04%), and Zephyr (+1.59%), to justify the generalizability of the planning engine.
