Evolvement model for scientific knowledge networks
Ma Feicheng · Systems Engineering - Theory & Practice · 2013
For the study of evolvement and dynamics of scientific knowledge,an evolvement model of scientific knowledge networks was constructed.By considered of the independent and crossing connection among different subjects,the model introduced three kinds of attachment strategies:local-world crossing attachment,preferential attachment of indegree,preferential attachment of time.Preferential attachment of in-degree could represent the inhabitation of classical scientific theories;preferential attachment of time showed the promotion of absorbing new knowledge,local-world crossing attachment presented topology of clustering character and satisfies the demand of inter-filed permeating.The simulation shows that the effect is global of the indegree preferential attachment and partial of the time-preferential attachment.
