Abstract: Internetware has become a new form of software now. However, how to choose reliable components to construct an internetware with as high reliability as possible, has become a serious problem We proposed a trust mechanism-based component selection model, which selects the more reliable component by way of the credibility evaluation of the components used before, the recommendation of friends, and the reputation of all the components. Then we proposed a component selection approach based on the selection model. At last, the results of experiment demonstrate the feasibility and validity of the approach.
