Résumé
The reputation of communities of web services mainly depends on their web services’ reputation. Masters of these communities have responsibility to choose which web services will join them, they consequently have to check their reputation. They cannot ask for this information directly to web services but they can request it from third parties called information services.Communities pay information services to get information, but web services with a bad reputation can also pay them to lie about their reputation in order to be accepted in communities. In such cases, information services have two choices : on one hand they can tell the truth and not receive reward from web services, on the other hand they can lie and loose the trust communities had placed in them. By means of a decision analysis using game theory and a simulation tool, we look for a mechanism ensuring information services honesty.
