About this paper
Haoxi Zhong, Chaojun Xiao, Cunchao Tu, Tianyang Zhang, Zhiyuan Liu, Maosong Sun
Zhong et al. (2020) present a comprehensive overview of Legal Artificial Intelligence (LegalAI), outlining the current Natural Language Processing (NLP) methodologies, key challenges, and future research directions. The work synthesizes embedding-based and symbol-based approaches, identifying a core performance-interpretability trade-off across tasks like legal judgment prediction, similar case matching, and legal question answering.
Key insights
- LegalAI research faces an inherent trade-off between the high performance of embedding-based NLP models and the crucial interpretability of symbol-based methods.
- Domain-specific pre-trained language models and the integration of symbolic legal knowledge are essential for improving performance in legal contexts with long texts and infrequent labels.
- A significant gap exists between current AI capabilities and human expertise in complex legal reasoning and multi-hop legal question answering.
