自然语言处理在现代医学信息学中起着至关重要的作用。它通过分析和提取概念将叙述性文本或非结构化数据转换为知识。一个全面的词汇系统是自然语言处理应用成功的基础,也是自然语言处理管道开始时必不可少的组成部分。由国家医学图书馆作为统一医学语言系统知识源之一分发的专业词典和词汇工具,为许多NLP应用程序提供了基础资源。本文报告了《大词典》中三个关键组成部分的最新进展。以统一医学语言系统概念图的核心NLP操作为例,说明了这些发展的重要性。我们的目标是为自然语言处理应用提供通用的、广泛的覆盖面和健壮的词汇系统。提出了一种新的多词方法和其他计划中的发展。
Natural language processing (NLP) plays a vital role in modern medical informatics. It converts narrative text or unstructured data into knowledge by analyzing and extracting concepts. A comprehensive lexical system is the foundation to the success of NLP applications and an essential component at the beginning of the NLP pipeline. The SPECIALIST Lexicon and Lexical Tools, distributed by the National Library of Medicine as one of the Unified Medical Language System Knowledge Sources, provides an underlying resource for many NLP applications. This article reports recent developments of 3 key components in the Lexicon. The core NLP operation of Unified Medical Language System concept mapping is used to illustrate the importance of these developments. Our objective is to provide generic, broad coverage and a robust lexical system for NLP applications. A novel multiword approach and other planned developments are proposed.
