摘要:

知识是一种形式化的认识世界的方式,为下一代人工智能提供了人类水平的认知和智能。知识的表示之一是实体之间的语义关系。关系抽取(RelationExtraction,RE)是信息抽取的一个子任务,是自动获取这些重要知识的有效途径,在自然语言处理(Natural Language Processing,NLP)中起着至关重要的作用。其目的是从自然语言文本中识别实体之间的语义关系。到目前为止,有几个研究RE在以前的作品,其中记录了这些技术的基础上,深度神经网络(DNN)成为一个流行的技术在这项研究中。特别是基于DNN的监督和远程监督方法是RE最流行和最可靠的解决方案。本文1)介绍了一些基本概念,2)从两个角度对分布式神经网络在RE中的应用进行了全面的概述:监督RE,它试图改进标准RE系统;远程监督RE,它采用分布式神经网络设计句子编码器和去噪方法。我们进一步3)涵盖了一些新的方法和最近的趋势,以及讨论可能的未来研究方向,这项任务。

英文摘要:

Knowledge is a formal way of understanding the world, providing a human-level cognition and intelligence for the next-generation artificial intelligence (AI). One of the representations of knowledge is semantic relations between entities. An effective way to automatically acquire this important knowledge, called Relation Extraction (RE), a sub-task of information extraction, plays a vital role in Natural Language Processing (NLP). Its purpose is to identify semantic relations between entities from natural language text. To date, there are several studies for RE in previous works, which have documented these techniques based on Deep Neural Networks (DNNs) become a prevailing technique in this research. Especially, the supervised and distant supervision methods based on DNNs are the most popular and reliable solutions for RE. This article 1) introduces some general concepts, and further 2) gives a comprehensive overview of DNNs in RE from two points of view: supervised RE, which attempts to improve the standard RE systems, and distant supervision RE, which adopts DNNs to design sentence encoder and de-noise method. We further 3) cover some novel methods and recent trends as well as discuss possible future research directions for this task.
