Abstract: We study multi-attribute trajectories by combining standard trajectories (i.e., a sequence of timestamped locations) and descriptive attributes. A new form of continuous k nearest neighbor queries is proposed by integrating attributes into the evaluation. To… read more here.

Abstract: In this paper, two strategies for handling continuous k-nearest neighbour queries for location-based services are proposed. CKNN1 and CKNN2 utilise a validity (i.e., safe) region approach for minimising the number of query requests that need… read more here.
