本文介绍了我们在开发一种新的司法判决自动摘要方法方面的工作。我们将LetSum (Legal text Sum- marizer)这一原型系统分为引言、语境、司法分析和结论四个主题来确定判决的主题结构。然后识别每个主题的相关句子。我们讨论了用统计方法对产出摘要的评价,以及基于法学家判断的人的评价。目前的结果表明,与其他的摘要技术相比,该系统具有良好的性能。
This paper presents our work on the development of a new methodology for automatic summarization of justice decision. We describe LetSum (Legal text Sum- marizer), a prototype system, which determines the thematic structure of a judgment in four themes INTRODUCTION, CONTEXT, JURIDICAL ANALYSIS and CONCLUSION. Then it identifies the relevant sentences for each theme. We discuss the evaluation of produced summaries with statistical method and also human evaluation based on jurist judgment. The results so far indicate good performance of the system when compared with other summarization technologies.
