Query processing over graph-structured data is enjoying a growing number of applications. A top-k keyword search query on a graph nds the top k answers according to some ranking criteria, where each answer is a substructure of the graph containing
Multiple Object Types KNN Search Using Network Voronoi Diagram Abstract. Existing work on k nearest neighbor (kNN) in spatial/mobile query processing focuses on single object types. Furthermore, they do not consider optimum path in KNN. In this pape
For many computer vision problems, the most time consuming component consists of nearest neighbor matching in high-dimensional spaces. There are no known exact algorithms for solving these high-dimensional problems that are faster than linear search
