SigMOD2012感兴趣的论文（时空数据处理）——记下慢慢看

图中联合做距离数据处理：

Efficient Processing of Distance Queries in Large Graphs: A Vertex Cover Approach, James Cheng, Nanyang Technological University; Yiping Ke, Institute of High Performance Computing, Singapore; Shumo Chu, Nanyang Technological University; Carter Cheng, Nanyang Technological University

图数据处理真的是火啊：

A Highway-Centric Labeling Approach for Answering Distance Queries on Large Graphs, Ruoming Jin, Kent State University; Ning Ruan, Kent State University; Yang Xiang, Ohio State University; Victor Lee, Kent State University

位置隐私，依旧有牛人推动：

Authenticating Location-Based Services without Compromising Location Privacy, Haibo Hu, HKBU; Jianliang Xu, HKBU; Ziwei Yang, HKBU

空间采样，看看有什么策略：

Efficient Spatial Sampling of Large Geographical Tables, Anish Das Sarma, Google; Hongrae Lee, Google; Hector Gonzalez, Google Research; Jayant Madhavan, Google Research; Alon Halevy, Google Research

最短路径的缓存，很有意思：

Effective Caching of Shortest Paths for Location-Based Services, Man Lung Yiu, Hong Kong Polytechnic University; Jeppe Thomsen, Hong Kong Polytechnic University; Christian Jensen, Aarhus University

Ｃｈｒｉｓｔｉａｎ教授太厉害了：

Parallel Main-Memory Indexing for Moving-Object Query and Update Workloads, Darius Sidlauskas, Aalborg University; Simonas Saltenis, Aalborg University; Christian Jensen, Aarhus University

类别关键字，看怎么优化：

Optimizing Index for Taxonomy Keyword Search, Bolin Ding, University of Illinois at Urbana Champaign; Haixun Wang, Microsoft Research Asia; Ruoming Jin, Kent State University; Jiawei Han, University of Illinois at Urbana Champaign; Zhongyuan Wang, Microsoft Research Asia
