In this paper, we investigate the application of text classification methods
to support law professionals. We present several experiments applying machine
learning techniques to predict with high accuracy the ruling of the French
Supreme Court and the law area to which a case belongs to. We also investigate
the influence of the time period in which a ruling was made on the form of the
case description and the extent to which we need to mask information in a full
case ruling to automatically obtain training and test data that resembles case
descriptions. We developed a mean probability ensemble system combining the
output of multiple SVM classifiers. We report results of 98% average F1 score
in predicting a case ruling, 96% F1 score for predicting the law area of a
case, and 87.07% F1 score on estimating the date of a ruling.

本研究使用文本分类和机器学习方法，研究法律专业人员的支持应用。通过实验研究法国最高法院的判决和案件所属法律领域的高准确度预测，发现判决作出的时间对案例描述的形式和数据蒙版的使用会有影响，研究了多个支持向量机分类器的平均概率集成系统，平均 F1 值为 98％，预测案例判决，96％ F1 值用于预测案件的法律领域，对于估计判决日期的 F1 值为 87.07％。

探索文本分类在法律领域的应用

Exploring the Use of Text Classification in the Legal Domain

In this paper, we investigate the application of text classification methods
to predict the law area and the decision of cases judged by the French Supreme
Court. We also investigate the influence of the time period in which a ruling
was made over the textual form of the case description and the extent to which
it is necessary to mask the judge's motivation for a ruling to emulate a
real-world test scenario. We report results of 96% f1 score in predicting a
case ruling, 90% f1 score in predicting the law area of a case, and 75.9% f1
score in estimating the time span when a ruling has been issued using a linear
Support Vector Machine (SVM) classifier trained on lexical features.

本文研究了如何将文本分类方法应用于法国最高法院判决案件的法律领域和判决预测，并调查了判决描述的文本形式在时间段上对判决的影响以及模拟真实世界测试情景需要遮盖法官动机的程度。我们使用基于词汇特征训练的线性支持向量机分类器报告了 96％的案件判决预测 f1 得分，90％的法律领域预测 f1 得分和 75.9％的发布判决时间跨度估计 f1 得分。
