English(EN) Beyond States: Investigating the Effects of Context on User Modeling with Feature-Conditioned Markov Models

新模型增强信息检索系统中用户行为的模拟

作者 PulseAugur 编辑部 · [1 个来源] · 2026-10-05 09:52

一篇新的研究论文介绍了一种特征条件马尔可夫风格的用户模型，旨在改进交互式信息检索系统中用户行为的模拟。该模型通过将位置、基于内容和交互派生特征等上下文信息纳入转移概率，来增强传统的马尔可夫模型。研究表明，包含这些上下文特征可以实现更真实的用户模拟，尽管其有效性因具体的搜索场景和建模目标而异，这表明需要进行特定任务和特定设置的特征选择。 AI

影响这项研究可以通过更好地模拟用户交互来更准确地评估信息检索系统。

超越状态：使用特征条件马尔可夫模型研究上下文对用户建模的影响

User behavior simulation is widely used to evaluate interactive information retrieval systems, but classical state-based approaches (e.g., Markov models) have limited ability to incorporate contextual information relevant for decision-making. We address this limitation by introdu…
