Abstract:In view of the difficulty of selecting crowdsourcing service providers caused by the lack of credit in crowdsourcing mode, this paper discusses how to select service providers by using online comment data on crowdsourcing platform. Based on competency model, 13 features that affect the selection of service providers are proposed from three aspects: service provider, platform and task design, the crowdsourcing service provider selection model based on online comment data is constructed, and the classification algorithm is used to implement the model. The experimental results show that,the service provider selection effect based on the combination of service provider, platform and task design is the best,and the best service provider selected by the model basically accords with the winning service provider selected by the contractor in the real data, so the validity of the model in practical application is verified.
