However, there are also problems such as mismatches between participating entities and low efficiency in solving crowdsourcing tasks. In order to improve the scientificity of the task decision made by the solver and match the suitable task for the solver from many tasks, this paper proposes a task recommendation method for the solver based on prospect theory. Firstly, the user demand system is constructed, and the solver’s demand is transformed into the evaluation indicators of innovative tasks. Then, the weight of demand is calculated by using the entropy method. In the intuitionistic fuzzy linguistic environment, prospect theory is introduced to express the psychological preference behavior of the acceptor under different risk prospects, and the positive and negative prospect matrices are constructed. Then, the total prospect value of each alternative task in different indicators is determined, and the comprehensive prospect value of each task is calculated. Based on the calculation results, the tasks are sorted and selected, and finally, the feasibility and effectiveness of the method are verified through empirical research on Zhubajie.com.展开更多
