Efficiently using contextual influence to recommend new items to ephemeral groups
作者:
Highlights:
• An approach to recommend new items to ephemeral groups is proposed.
• Our strategy relies on contextual influence.
• Contextual influence is the ability of a user, in a given context, to guide the group’s decision.
• An algorithm to efficiently generate recommendation lists at runtime is also presented.
• Accuracy and efficiency are experimentally evaluated using a real TV dataset.
