Abstract: Provided are a method of training a prediction model, a prediction method, an electronic device and a medium, which relate to the field of artificial intelligence technology, and in particular, to the field of Big Data. A prediction model includes a main prediction model and an auxiliary prediction model, a training sample set includes a project information sample of a project and an item information sample of an item associated with the project, a project information sample includes a project property information and a project comment information, and an item information sample includes an item comment information. The method includes: inputting the project comment information to the auxiliary prediction model to obtain an initial prediction semantic information; training the main prediction model by using the project property information and the initial prediction semantic information; and training the auxiliary prediction model by using the item comment information.
