Model construction method and device, storage medium and processor

The invention provides a model construction method and device, a storage medium and a processor. The method comprises the steps of obtaining online data; carrying out crowdsourcing annotation on the online data to obtain an annotation result, wherein the annotation result comprises annotated training data and annotation condition information; obtaining the labeling quality of the labeling result; selecting a corresponding machine learning model and a corresponding model training parameter according to the current task type and the labeling quality of the labeling result; training the corresponding machine learning model by using the labeled training data according to the corresponding model training parameters to obtain a trained prediction model. According to the method, the online data and the modeling configuration process are combined, automatic configuration of the model and the model training parameters is realized, the modeling threshold of non-professionals is fully reduced, the whole modeling process
