本文提出NOWJ1团队在ALQAC 2023中的方法,通过结合经典统计模型与预训练语言模型,并采用学习排序和子任务拆分策略,有效提升了法律文档检索与问答任务的性能。

摘要:

本文描述了NOWJ1团队参加2023年自动化法律问答竞赛(ALQAC)的方法,该竞赛的重点是通过整合经典统计模型和预训练语言模型(PLMs)来提升法律任务性能。在文档检索任务中,我们实现了一个预处理步骤以克服输入限制,并应用学习排序(learning-to-rank)方法来整合来自不同模型的特征。问答任务被分为两个子任务:句子分类和答案抽取。我们引入最先进的模型,为每个子任务开发不同的系统,同时利用经典统计模型和预训练语言模型。实验结果表明,我们提出的方法在竞赛中展现出有前景的潜力。

英文摘要:

This paper describes the NOWJ1 Team's approach for the Automated Legal Question Answering Competition (ALQAC) 2023, which focuses on enhancing legal task performance by integrating classical statistical models and Pre-trained Language Models (PLMs). For the document retrieval task, we implement a pre-processing step to overcome input limitations and apply learning-to-rank methods to consolidate features from various models. The question-answering task is split into two sub-tasks: sentence classification and answer extraction. We incorporate state-of-the-art models to develop distinct systems for each sub-task, utilizing both classic statistical models and pre-trained Language Models. Experimental results demonstrate the promising potential of our proposed methodology in the competition.
