A SYSTEM FOR PROVIDING RECOMMENDATION INFORMATION FOR USER DEVICE

摘要

Information recommendation system comprises cloud and user device. Cloud stores first virtual data of objects. Each object is associated with geographical information and user- independent/user-dependent attribute. Cloud selects second virtual data of objects based on device location, and transmits it to user device. User device comprises four modules. Data preparation module stores received second virtual data in local storage. Data preparation module detects device location change, informs cloud, and updates local data in response to new second virtual data. User-independent data module retrieves user-independent data from local storage. User-dependent data module retrieves user-dependent data from local storage, and filters/weights/ranks retrieved data. Weighting is performed based on user's preference. Ranking is performed based on weighting when there are multiple items found simultaneously. Display module receives data from data modules. Display module applies predefined policies to display virtual data objects, and ranks data when there are multiple items at the same time.
