The invention particularly relates to a class case pushing method and device based on case description. The class case pushing method based on case description comprises the following steps: firstly,hierarchically encoding each paragraph of a decision by means of a deep learning model, forming features according to the context encoding of the paragraph, performing binary classification modeling through a multi-layer perceptron, generating a case description judgment model through training, and extracting case description of a to-be-processed decision by using the model; secondly, constructinga decision-making case description potential semantic space; and finally, mapping a query statement input by the user to a potential semantic space, calculating the similarity between the query statement and all case description vectors, sorting according to the similarity, and recommending a decision corresponding to the TopK case description to the user. According to class case pushing method and device, the influence of other types of elements except the case description is reduced, the class case pushing effect is improved, the case description can be accurately extracted from the decision, and the method and device are suitable for popularization and application.
