Finding fastest paths on a road network with speed patterns
by Evangelos Kanoulas, Yang Du, Tian Xia, Donghui Zhang — 2006 — In Proc. Int. Conf. on Data Engineering (ICDE’06
…This paper proposes and solves the Time-Interval All Fastest Path (allFP) query. Given a user-defined leaving or arrival time interval I, a source node s and an end node e, allFP asks for a set of all fastest paths from s to e, one for each sub-interval of I. Note that the query algorithm should fin…

On Computing Top-t Most Influential Spatial Sites
by Tian Xia, Donghui Zhang, Evangelos Kanoulas, Yang Du — 2005 — IN VLDB
…Given a set O of weighted objects, a set S of sites, and a query site s, the bichromatic RNN query computes the influence set of s, or the set of objects in O that consider s as the nearest site among all sites in S. The influence of a site s can be defined as the total weight of its RNNs. Thi…
