Abstract:
Presenting location-based services (LBSs) in mobile information environments has been developing quantitatively and qualitatively each day. The most important ingredient of such services is map. The fundamental map elements like information contents, scale and other graphical items are related to the spatial resolution of user or device. Thus, map resolution is an integral part of LBSs. One of the less-attended issues so far is determining the resolution of maps that are going to indicate some information to users. In this paper, a context-aware approach is presented to determine the resolution of maps used in LBSs. In fact, the map’s resolution is computed using fuzzy inference engine based on two basic contexts of location and time. In this method, user’s location and the time of request are inputs to the fuzzy inference system. The map’s resolution for indicating information to user is the system’s output. Fuzzy rule base is developed by grouping and consulting users. The proposed approach was implemented for a group of faculty members and the results proved the applicability of the method for other user groups.
