Processing Group Nearest Group Query
2009 IEEE 25th International Conference on Data Engineering, 2009Given a data point set D, a query point set Q and an integer k, the Group Nearest Group (GNG) query finds a subset of points from D, ω (|ω| ≤ k), such that the total distance from all points in Q to the nearest point in ω is no greater than any other subset of points in D, ω' (|ω'| ≤ k). GNG query can be found in many real applications.
