A Group Trust Model with Control Flow Constraint Based on Bayesian Method

From perspective of objectivity of trust, a group Trust model which is used to depict constraint relationships among individuals in a particular group through covering four basic constraint patterns and their nesting; what's more, gauging methods of direct trust degree and recommendation trust degree of basic constraint patterns and their nesting are brought up based on Bayesian method, and these methods remarkably support group trust relationship, especially trust relationship of software groups. Analysis on expressive power and validity of group Trust model proves that this model has outstanding adaptability and practicability.
