论文摘要
现代在线服务不断以非常快速的速度生成数据。数据的连续流包含内容 - 例如,帖子,新闻,产品,评论 - ,以及用户反馈 - 例如,评分,视图,读取,读取,点击 - 与上下文数据 - 用户设备,空间或时间数据,用户任务或活动,天气,天气。考虑到内容,上下文和用户的偏好或意图的不断变化,旨在批量训练的系统和算法可能是压倒性的。因此,研究能够透明地适应在线服务的固有动态的在线方法很重要。从数据流中学习的增量模型在推荐系统社区中引起了人们的关注,因为它们自然地处理了在动态,复杂环境中产生的数据的连续流动。用户建模和个性化尤其可以从能够逐步维护模型的算法中受益。 该研讨会的目的是促进贡献并汇集一个越来越多的研究人员和从业人员社区,对在线,适应性的方法对用户建模,建议和个性化的方法及其对多个维度的影响,例如评估,可重复性,隐私性和解释性。
Modern online services continuously generate data at very fast rates. This continuous flow of data encompasses content - e.g., posts, news, products, comments -, but also user feedback - e.g., ratings, views, reads, clicks -, together with context data - user device, spatial or temporal data, user task or activity, weather. This can be overwhelming for systems and algorithms designed to train in batches, given the continuous and potentially fast change of content, context and user preferences or intents. Therefore, it is important to investigate online methods able to transparently adapt to the inherent dynamics of online services. Incremental models that learn from data streams are gaining attention in the recommender systems community, given their natural ability to deal with the continuous flows of data generated in dynamic, complex environments. User modeling and personalization can particularly benefit from algorithms capable of maintaining models incrementally and online. The objective of this workshop is to foster contributions and bring together a growing community of researchers and practitioners interested in online, adaptive approaches to user modeling, recommendation and personalization, and their implications regarding multiple dimensions, such as evaluation, reproducibility, privacy and explainability.
