摘要:

法律诉讼需要大量的时间,也花费了很多。律师必须做大量工作才能识别先前案件和法规的不同部分。本文试图解决将在FIRE 2021(信息检索评估论坛)上举办的AILA 2021(人工智能法律援助)的第一批任务。该任务是语义分割的文件到不同的分配的7个预定义的标签或“修辞角色。“本文使用BERT从句子中获得句子嵌入,然后使用线性分类器输出最终预测。实验结果表明,对出现频率最高的类赋予更多的权重,其结果要优于对出现频率较低的类赋予更多的权重。在任务1中,团队legalNLP获得了0.22的F1分数。

英文摘要:

Legal proceedings take plenty of time and also cost a lot. The lawyers have to do a lot of work in order to identify the different sections of prior cases and statutes. The paper tries to solve the first tasks in AILA2021 (Artificial Intelligence for Legal Assistance) that will be held in FIRE2021 (Forum for Information Retrieval Evaluation). The task is to semantically segment the document into different assigned one of the 7 predefined labels or "rhetorical roles." The paper uses BERT to obtain the sentence embeddings from a sentence, and then a linear classifier is used to output the final prediction. The experiments show that when more weightage is assigned to the class with the highest frequency, the results are better than those when more weightage is given to the class with a lower frequency. In task 1, the team legalNLP obtained a F1 score of 0.22.
