Research Progress in Pattern Mining for Big Spatio-temporal Trajectories

Ji Genlin;Zhao Bin;School of Computer Science and Technology,Nanjing Normal University;  
Spatio-temporal trajectory pattern mining has emerged as an active research field,focusing on the research and development of mining technology for big spatio-temporal trajectories to discover useful rules and knowledge.This paper attempts to review the recent research progress in spatio-temporal trajectory pattern mining and knowledge discovery.Then the background,application and advances of spatiotemporal trajectory pattern mining are introduced.And the research contents,system infrastructure and key technologies in big spatio-temporal trajectory pattern mining are discussed.Finally,the mining algorithm ideas for frequent pattern,flock pattern,gathering pattern,outlier pattern of spatio-temporal trajectory are expounded.
