| 摘 要： | 为了从大量的时空数据集中挖掘类似于星型和序列型的多元关联规则模式,首先,针对要素同类和关系同质,提出多元关联模式的概念,即多类别和多要素下的多规则的关联组合;其次,用图论的方法构建常见的星型和序列型等多元关联模式;再次,提出多元关联模式的挖掘算法,引入等价类,搭建多元关联模式。合成实例(城市规划)说明多元关联模式的时空数据挖掘模式及其挖掘算法具有可用性。 |

| Abstract: | To mine multivariate association patterns(MVAP),such as star-like and sequence multivariate association patterns,from large spatiotemporal datasets,a combination of multi-class-features(MCF) and multi-association-rules(MAR) was proposed according to entity types and relationships.The MVAP was then established based on the methods of graph theory.A new MVAP algorithm was presented by introducing Equivalence Classes to quickly identify MVAP.By use of an example in urban planning used to explain the MVAP proce... |
