Trajectories contain considerable routing information, and trajectory-based routing gains the attention of researchers recently. This paper argues the problem of searching time period Longest Frequent Path(TPLFP). The TPLFP, as one of the reasonable alternative Most Frequent Path (MFP), is close to MFP enough and maximizes the number of frequent route segments. First, we define TPLFP formally. To...
One of the most important kinds of queries in spatial network databases (SNDB) to support location-based services (LBS) is the shortest path query. Given an object in a network, e.g. a location of a car on a road network, and a set of objects of interests, e.g. hotels, gas station, car, etc., the k-NN query returns the k nearest neighbors from the query object to interested objects. This paper proposes...
