摘要

我们提出了一个非事实性的QA系统，该系统为法律领域的用户输入问题提供法律上准确、司法上相关和对话式响应的答案。这个商业上可用的系统完全基于NLP和IR，不依赖于结构化的知识库。WestSearch Plus旨在为有关法律的基本问题提供简洁的一句话答案。它的范围不限于特定主题或司法管辖区。潜在答案的语料库包含大约2200万份文档，分类为超过12万个法律主题。

WestSearch Plus: A Non-factoid Question-Answering System for the Legal Domain

We present a non-factoid QA system that provides legally accurate, jurisdictionally relevant, and conversationally responsive answers to user-entered questions in the legal domain. This commercially available system is entirely based on NLP and IR, and does not rely on a structured knowledge base. WestSearch Plus aims to provide concise one sentence answers for basic questions about the law. It is not restricted in scope to particular topics or jurisdictions. The corpus of potential answers contains approximately 22M documents classified to over 120K legal topics.
