Embodiment Construction
[0026] The present invention is described in further detail below in conjunction with the accompanying drawings and specific embodiments:
[0027] like figure 1 As shown, the present invention comprises the following steps:
[0028] 1) Preprocess the historical data in the crowdsourcing platform, obtain the preprocessed historical data, and establish a task feature matrix and a user feature matrix based on the preprocessed historical data; the historical data includes the attribute information of tasks and users. The task feature matrix and user feature matrix are constructed based on the standardized information of tasks and users, respectively.
[0029] In step 1), standardized information is extracted from the task and user attribute information in the historical data by using the natural language NLP method, respectively, and the standardized information of the task and the user is obtained respectively, and the preprocessed historical data is composed of the standardized...
