The invention discloses a class case pushing method and device based on a composite voting mechanism, and the method comprises the steps: inputting an information network into a preset unsupervised learning model, and obtaining a plurality of judgment documents of which the similarity with a case description is greater than a preset threshold value; and inputting the text embedding matrix of the case description into the supervised learning model to obtain a crime name of the case description. And taking the plurality of judgment documents of which the similarity with the case description is greater than a preset threshold value and the crime name of the case description as a reference basis of a voting mechanism, and selecting a target judgment document from the judgment documents by utilizing the voting mechanism to serve as an externally pushed judgment document. The output result of the unsupervised learning model (namely the multiple judgment documents with the similarity with the case description larger than the preset threshold) and the output result of the supervised learning model serve as the reference basis of a voting mechanism, the target judgment document is selected from all the judgment documents through the voting mechanism, and the accuracy of class case pushing can be remarkably improved.
Description
technical field [0001] The present application relates to the technical field of machine learning, in particular to a method and device for pushing similar cases based on a compound voting mechanism. Background technique [0002] Against the backdrop of the era of the intelligent revolution, the construction of intelligent justice is in full swing and progress has been made in stages. At the same time, how to carry out semantic retrieval and effectively use the massive cases in the judicial system has become a consensus in the research of smart justice and computational law. Pushing similar cases, as a core application in the field of smart justice, has received widespread attention. [0003] At present, the traditional push method for similar cases is: to count the occurrence frequency of each term in the description of the case, based on the word frequency information, and based on the term frequency-inverse document frequency (TF-IDF for short), calculate the case Descr...
