Abstract

In the service computing mode,affection behaviour was employed to improve the efficiency of service composition.Firstly,an affection space was built to meet behaviour demands,and cognition was defined to reason state change of affection.In the change processing,mapping was done between affection and cognition,and emotion decay and emotion update were defined to maintain the stability of affective change.Secondly,affective mechanism was put into ant colony algorithm,which formed an affection ant colony algorithm,and the algorithm was applied to Web Service Modeling Ontology(WSMO) service composition.Finally,the paper adopted a Virtual Travel Agency(VTA) example under WSMO to show this approach was effective and feasible.
