Abstract

Legal Tech is developed to help people with legal services and solve legal problems via machines. To achieve this, one of the key requirements for machines is to utilize legal knowledge and comprehend legal context. This can be fulfilled by natural language processing (NLP) techniques, for instance, text representation, text categorization, question answering (QA) and natural language inference, etc. To this end, we introduce a freely available Chinese Legal Tech system (IFlyLegal) that benefits from multiple NLP tasks. It is an integrated system that performs legal consulting, multi-way law searching, and legal document analysis by exploiting techniques such as deep contextual representations and various attention mechanisms. To our knowledge, IFlyLegal is the first Chinese legal system that employs up-to-date NLP techniques and caters for needs of different user groups, such as lawyers, judges, procurators, and clients. Since Jan, 2019, we have gathered 2,349 users and 28,238 page views (till June, 23, 2019).

Highlights

  • The term Legal Tech refers to legal technologies that apply computer technologies to legal services, such as legal consultation and judicial document analysis

  • Researchers are concentrating on enhancing Legal Tech with natural language processing (NLP) techniques (e.g., named entity recognition (Yin et al, 2018), sequence labeling (Yan et al, 2018))

  • Despite of plentiful advances in NLP, most of industrial applications remain constructed in conventional information retrieval (IR) manner or highly rely on hand-crafted responses

Summary

Introduction

The term Legal Tech refers to legal technologies that apply computer technologies to legal services, such as legal consultation and judicial document analysis Such techniques are able to ease the load of legal workers and provide accessible services for clients. Despite of plentiful advances in NLP, most of industrial applications remain constructed in conventional information retrieval (IR) manner or highly rely on hand-crafted responses. Taking advantage of recent advances in NLP, the legal system can act as an artificial lawyer for clients and as an assistant for legal workers It is a practical system for answering legal questions, performing law searching in multiple modes, and analyzing case descriptions.
