摘要:

家庭娱乐系统以具有一个或多个同时用户的各种使用场景为特征,对于这些用户而言,选择要消费的媒体的复杂性在过去十年中迅速增加。用户的决策过程是复杂的,高度受上下文环境的影响,但支持上下文感知推荐系统的开发和评估的数据是稀缺的。在本文中,我们提出了一个数据集的自我报告的电视消费丰富的上下文信息的观看情况。我们展示了体裁的选择如何与当前用户的数量和用户的注意力水平相关联。此外,我们评估的性能,预测所选择的类型给定不同的配置的上下文信息,并比较结果的上下文无关的预测。结果表明,包括上下文特征的预测引起显着的改善,时间和社会背景显示出显着的贡献。

英文摘要:

Home entertainment systems feature in a variety of usage scenarios with one or more simultaneous users, for whom the complexity of choosing media to consume has increased rapidly over the last decade. Users' decision processes are complex and highly influenced by contextual settings, but data supporting the development and evaluation of context-aware recommender systems are scarce. In this paper we present a dataset of self-reported TV consumption enriched with contextual information of viewing situations. We show how choice of genre associates with, among others, the number of present users and users' attention levels. Furthermore, we evaluate the performance of predicting chosen genres given different configurations of contextual information, and compare the results to contextless predictions. The results suggest that including contextual features in the prediction cause notable improvements, and both temporal and social context show significant contributions.
