Knowledge representation model of spatio-temporal change
Yingjun Zhang · Computer Engineering and Applications Journal · 2008
In order to eliminate the semantic heterogeneity in representing process of the spatio-temporal changes,a three-tuple model CAR for representing the spatio-temporal change is proposed based on the geographical object set before change and the geographical object set after change,change type and rules.In this model,the C denotes the change type;A denotes the attribute set;R denotes the judging rules of change type.The rule is described by the IF-THEN expressions.By the operations between R and A,the C is distinguished.This model overcomes the limitations of current methods.And more,the rules in this model can be easy realized in computer program.
