LocateXpert

LocateXpert是针对移动用户的本地感知新闻源系统。

LocateXpert, a new LANF (local aware news feed) system enables a user to specify the minimum number of message of categories for the messages in a news feed. It send the most relevant geo-tagged messages to their users. News feed may contain messages related to the same location or the same category of locations.We argue that diversity is a very important feature for location-aware news feeds because it helps users discover new places and activities. Our objective is to efficiently schedule news feed for a mobile user at user current and predicted locations, such that i) each news feed contains messages belonging to at least 'h' different categories, and ii) their total relevance to the user is maximized.
