Bob is an employee of a Paris-based multinational company and, due to official commitments, travels frequently between France and the USA.
The organization of the paper begins with related work, followed by technical details on augmentation of the platform's functionality, a description of the recommendation model and its back-tested prediction results, and finally an articulation of the design decisions that went into deploying the recommendation framework in a live course.
Restaurants is an obvious place type to tackle with this sort of crowdsourced recommendation model, but it's far from the only category where such a thing would prove useful.
The results show suitability of using this recommendation model, in order to suggest online learning activities to learners based on their learning style, knowledge and preferences.
Additionally, the approach presents other advantages, as the low computational cost and the use of an unified recommendation model for representing positive and negative feedback and collaborative image retrieval.
Also most of the recommendation models consider the aggregate of recommendations; in that case malicious entity can go undetected.
Due to the accumulation and variation of preference, in the recommendation model we conduct an adaptive method including long-term and short-term preference adjustment to enhance the result of recommendation.
