The Contextual Group Recommendation

The context-aware calculation method is applied to the model of recommendation system in this paper. Based on context of scenario analysis and inference, we can implement recommendation for user group. This paper makes use of the context of scenarios aware technology, which fuses multi-source data from smart phones, sensor networks and social networks for the scenario modeling and inference, and then formats the context clues to build the perceptual model of the context scenarios to predict the behavior patterns of the user group for the group recommendation, which meet the needs of the user group. We have analyzed the recommendation process and performed a subjective test to show the usefulness of the proposed system.
