is descri bed.Depending on matrix shift and calculation
rippleeffect of ontology evolut ion can be analyzed and its quantity can be ascertained.Every rippleeffect cau sed by ontology change operation is described.At the same time
approaches for calculating ontology element contribution
ontology cohesions and effect degree applied to every ontology element during ontology evolution
are provided.Rippl eeffect analysis for dependencyunknown ontology evolution is discussed
and a server model for ontology evolution is also provided.All are credible foundatio n for management
