DAIAN通过动态感知用户意图,提升触发推荐的精准度。

DAIAN: Deep Adaptive Intent-Aware Network for CTR Prediction in Trigger-Induced Recommendation

  • 基于用户点击与触发项的相关性,动态提取个性化意图表征。
  • 融合ID与语义信息增强相似性,缓解行为稀疏带来的性能瓶颈。
  • 适用于电商实时推荐场景,尤其适合意图多变的用户群体。

推荐系统在个性化电商购物体验中至关重要。其中,触发式推荐(TIR)作为一种关键场景,利用触发项(明确代表用户即时兴趣)实现精准、实时推荐。尽管已有多种基于触发的方法,但大多存在意图短视问题,即过度强调触发项作用,仅聚焦于与触发项高度相关商品的推荐。同时,现有方法依赖触发项与推荐项之间的协同行为模式识别用户偏好,但基于ID的交互稀疏性限制了其效果。为此,我们提出深度自适应意图感知网络(DAIAN),动态适配用户意图偏好。具体而言,首先通过分析用户点击与触发项的相关性,提取个性化意图表征,并据此检索用户相关历史行为以挖掘多样化意图;此外,为克服稀疏协同行为对意图关联项捕捉的制约,采用结合ID与语义信息的混合增强器强化相似性,并根据不同意图进行自适应选择。在公开数据集及工业级电商数据集上的实验表明,DAIAN具有显著有效性。

原文摘要 · Abstract (English)

Recommendation systems are essential for personalizing e-commerce shopping experiences. Among these, Trigger-Induced Recommendation (TIR) has emerged as a key scenario, which utilizes a trigger item (explicitly represents a user's instantaneous interest), enabling precise, real-time recommendations. Although several trigger-based techniques have been proposed, most of them struggle to address the intent myopia issue, that is, a recommendation system overemphasizes the role of trigger items and narrowly focuses on suggesting commodities that are highly relevant to trigger items. Meanwhile, existing methods rely on collaborative behavior patterns between trigger and recommended items to identify the user's preferences, yet the sparsity of ID-based interaction restricts their effectiveness. To this end, we propose the Deep Adaptive Intent-Aware Network (DAIAN) that dynamically adapts to users' intent preferences. In general, we first extract the users' personalized intent representations by analyzing the correlation between a user's click and the trigger item, and accordingly retrieve the user's related historical behaviors to mine the user's diverse intent. Besides, sparse collaborative behaviors constrain the performance in capturing items associated with user intent. Hence, we reinforce similarity by leveraging a hybrid enhancer with ID and semantic information, followed by adaptive selection based on varying intents. Experimental results on public datasets and our industrial e-commerce datasets demonstrate the effectiveness of DAIAN.
