摘要:

个性化是搜索引擎提高用户体验的重要手段。现有的工作大多做纯特征工程,提取大量的会话风格的特征,然后训练一个排序模型。在这里,我们提出了一种新的方法来建模的长期和短期的用户行为使用多臂强盗算法。该算法可以很好地泛化用户间的会话信息,并且作为一种Explore-Exploit风格的算法,它可以很好地泛化到新的URL和新的用户。实验结果表明,该算法的性能优于默认排序,优于几种流行的多臂强盗算法。

英文摘要:

Personalization is important for search engines to improve user experience. Most of the existing work do pure feature engineering and extract a lot of session-style features and then train a ranking model. Here we proposed a novel way to model both long term and short term user behavior using Multi-armed bandit algorithm. Our algorithm can generalize session information across users well, and as an Explore-Exploit style algorithm, it can generalize to new urls and new users well. Experiments show that our algorithm can improve performance over the default ranking and outperforms several popular Multi-armed bandit algorithms.
