Abstract
The task of prison term prediction is to predict the term of penalty based on
textual fact description for a certain type of criminal case. Recent advances in deep
learning frameworks inspire us to propose a two-step method to address this problem. To
obtain a better understanding and more specific representation of the legal texts, we
summarize a judgment model according to relevant law articles and then apply it in the
extraction of case feature from judgment documents. By formalizing prison term
prediction as a regression problem, we adopt the linear regression model and the neural
network model to train the prison term predictor. In experiments, we construct a realworld dataset of theft case judgment documents. Experimental results demonstrate that
our method can effectively extract judgment-specific case features from textual fact
descriptions. The best performance of the proposed predictor is obtained with a mean
absolute error of 3.2087 months, and the accuracy of 72.54% and 90.01% at the error
upper bounds of three and six months, respectively.
