Finding Multiple New Optimal Locations in a Road Network
Ruifeng Liu, Ada WaiChee Fu, Zitong Chen +2
We study the problem of optimal location querying for location based services in road networks, which aims to find locations for new servers or facilities. The existing optimal sol…
Hop Doubling Label Indexing for Point-to-Point Distance Querying on Scale-Free Networks
Minhao Jiang, Ada Wai-Chee Fu, Raymond Chi-Wing Wong +1
We study the problem of point-to-point distance querying for massive scale-free graphs, which is important for numerous applications. Given a directed or undirected graph, we propo…
(α, k)-Minimal Sorting and Skew Join in MPI and MapReduce
Silu Huang, Ada Wai-Chee Fu
As computer clusters are found to be highly effective for handling massive datasets, the design of efficient parallel algorithms for such a computing model is of great interest. We…
IS-LABEL: an Independent-Set based Labeling Scheme for Point-to-Point Distance Querying on Large Graphs
Ada Wai-Chee Fu, Huanhuan Wu, James Cheng +2
We study the problem of computing shortest path or distance between two query vertices in a graph, which has numerous important applications. Quite a number of indexes have been pr…
Inferential or Differential: Privacy Laws Dictate
Ke Wang, Peng Wang, Ada Waichee Fu +1
So far, privacy models follow two paradigms. The first paradigm, termed inferential privacy in this paper, focuses on the risk due to statistical inference of sensitive information…
Small Count Privacy and Large Count Utility in Data Publishing
Ada Wai-Chee Fu, Jia Wang, Ke Wang +1
While the introduction of differential privacy has been a major breakthrough in the study of privacy preserving data publication, some recent work has pointed out a number of cases…
