摘要:

按内在质量对在线评论进行排序,是电子商务平台和信息服务的一项关键任务,它影响着用户体验和业务成果。然而,质量是一个依赖领域且动态变化的概念,这使得对其评估成为一个重大挑战。依赖手工特征的传统方法在不同领域间难以扩展,并且无法适应不断变化的内容模式,而现代深度学习方法往往产生黑盒模型,缺乏可解释性,并且可能优先考虑语义而非质量。为了应对这些挑战,我们提出了AutoQual,一个基于LLM的智能体框架,用于自动化发现可解释特征。虽然在评论质量评估上进行了展示,但AutoQual被设计为一个通用框架,用于将数据中蕴含的隐性知识转化为显式的、可计算的特征。它模拟人类研究过程,通过反思迭代地生成特征假设,通过自主工具实现将其操作化,并在持久记忆中积累经验。我们在一个拥有十亿级用户的大型在线平台上部署了我们的方法。大规模A/B测试证实了其有效性,使得每个用户的平均评论浏览数增加了0.79%,评论读者的转化率提高了0.27%。

英文摘要:

Ranking online reviews by their intrinsic quality is a critical task for e-commerce platforms and information services, impacting user experience and business outcomes. However, quality is a domain-dependent and dynamic concept, making its assessment a formidable challenge. Traditional methods relying on hand-crafted features are unscalable across domains and fail to adapt to evolving content patterns, while modern deep learning approaches often produce black-box models that lack interpretability and may prioritize semantics over quality. To address these challenges, we propose AutoQual, an LLM-based agent framework that automates the discovery of interpretable features. While demonstrated on review quality assessment, AutoQual is designed as a general framework for transforming tacit knowledge embedded in data into explicit, computable features. It mimics a human research process, iteratively generating feature hypotheses through reflection, operationalizing them via autonomous tool implementation, and accumulating experience in a persistent memory. We deploy our method on a large-scale online platform with a billion-level user base. Large-scale A/B testing confirms its effectiveness, increasing average reviews viewed per user by 0.79% and the conversion rate of review readers by 0.27%.
