CBPF:利用上下文和内容信息提供更好的建议

CBPF: leveraging context and content information for better recommendations

Zahra Vahidi Ferdousi, Dario Colazzo, Elsa Negre

摘要:

推荐系统帮助用户在大量的信息中找到合适的项目。已经提出了不同类型的推荐系统。其中,上下文感知推荐系统的目标是尽可能多地个性化的建议,根据上下文的情况下,用户是。在本文中,我们提出了一种方法集成到推荐过程中的上下文信息建模无论是基于项目的或基于用户的影响的情况下,评级,使用皮尔逊相关系数。所提出的解决方案的目的是在推荐过程中利用内容和上下文信息。我们评估并显示我们的方法在三个不同的上下文数据集上的有效性,并根据这些数据集的特性,特别是输入数据的稀疏程度和可用信息量,分析我们的方法的变体的性能。

英文摘要:

Recommender systems help users to find their appropriate items among large volumes of information. Different types of recommender systems have been proposed. Among these, context-aware recommender systems aim at personalizing as much as possible the recommendations based on the context situation in which the user is. In this paper we present an approach integrating contextual information into the recommendation process by modeling either item-based or user-based influence of the context on ratings, using the Pearson Correlation Coefficient. The proposed solution aims at taking advantage of content and contextual information in the recommendation process. We evaluate and show effectiveness of our approach on three different contextual datasets and analyze the performances of the variants of our approach based on the characteristics of these datasets, especially the sparsity level of the input data and amount of available information.
