句法分析前沿动态综述

句法分析的目标是分析输入句子并得到其句法结构,是自然语言处理领域的经典任务之一。目前针对该任务的研究主要集中于如何通过从数据中自动学习来提升句法分析器的精度。该文对句法分析方向的前沿动态进行了调研,分别从有监督句法分析、无监督句法分析和跨领域跨语言句法分析三个子方向梳理和介绍了2018—2019年发表的新方法和新发现,并对句法分析子方向的研究前景进行了分析和展望。

A Survey of Recent Developments in Syntactic Parsing

Syntactic parsing aims to analyze an input sentence for its syntactic structure. It is one of the most classic tasks in natural language processing. Current researches of syntactic parsing are focused on improving the accuracy of syntactic parsers via automatic learning from data. This paper surveys recent developments in syntactic parsing, classifies and introduces the new approaches and new discoveries over the past year in three subareas (supervised parsing, unsupervised parsing, and cross-domain/cross-language parsing), and finally discusses the future perspective of syntactic parsing research.
