Navigation announcement risk identification model construction method and device, equipment and storage medium

The invention discloses a navigation announcement risk identification model construction method and device, equipment and a storage medium, and the method comprises the steps: marking risk category data for obtained navigation announcement historical data, and constructing a risk corpus; dividing data in the risk corpus into a training set and a test set; performing word segmentation and stop word removal on data in the training set and the test set to obtain navigation announcement word list data; performing feature extraction on the navigation announcement word list data to obtain feature representation; and carrying out fully supervised training on the feature representation by adopting an identification model pre-established by a support vector machine based on natural language processing, and outputting a trained optimal model as a risk identification model. The risk identification model constructed by the invention can improve the efficiency and precision of navigation announcement risk identification.
