首先发展了基于事件影响域的时空事务表构建策略,提出了基于事件影响域的时空关联规则挖掘方法,给出了相应的挖掘算法(简称ECSTAR算法)。通过一个实际算例验证了所提方法的可行性和有效性。 更多还原

【Abstract】 Spatio-temporal association rules mining is a key technology and a hot issue in the field of spatio-temporal data mining.The classical Apriori algorithm is usually utilized to detect the spatio-temporal association rules from the spatio-temporal transaction table,which is derived from the original spatio-temporal data.In most existing approaches to generate the spatio-temporal transaction table,many defects,such as data redundancy,further affects the efficiency of spatio-temporal association rul... 更多还原
