Abstract

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.

统一医学语言系统SPECIALIST词汇和词汇工具：开发和应用。

摘要

自然语言处理（NLP）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。全面的词汇系统是NLP应用程序成功的基础，并且是NLP流程开始时的重要组成部分。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SPECIALIST词典和词汇工具为许多NLP应用程序提供了基础资源。本文报告了词典中3个关键组件的最新发展。统一医学语言系统概念映射的NLP核心操作用于说明这些开发的重要性。我们的目标是为NLP应用程序提供通用，广泛的覆盖范围和健壮的词汇系统。
