摘要:

在法律信息抽取/蕴涵竞赛(COLIEE)的背景下,我们提出了一种方法,该方法包括必要的步骤,用于查找法律问题的相关文件,并决定文本蕴涵证据以提供正确的答案。该方法基于多个词汇和形态特征的组合,建立语言模型和一组特征,用于机器学习算法。我们提供了一个详细的研究所提出的方法的性能和失败的情况下,表明它是具有竞争力的国家的最先进的方法,法律信息检索和问答,而不需要广泛的训练数据,也不依赖于专家产生的知识。所提出的方法在竞赛中取得了显著的成绩,表明所处理的任务具有相当高的充分性。

英文摘要:

In the context of the Competition on Legal Information Extraction/Entailment (COLIEE), we propose a method comprising the necessary steps for finding relevant documents to a legal question and deciding on textual entailment evidence to provide a correct answer. The proposed method is based on the combination of several lexical and morphological characteristics, to build a language model and a set of features for Machine Learning algorithms. We provide a detailed study on the proposed method performance and failure cases, indicating that it is competitive with state-of-the-art approaches on Legal Information Retrieval and Question Answering, while not needing extensive training data nor depending on expert produced knowledge. The proposed method achieved significant results in the competition, indicating a substantial level of adequacy for the tasks addressed.
