Current approaches to the expansion of semantic lexicons for corpus annotation are somewhat ad hoc in nature and do not generally offer a systematic means of identifying areas for development within one’s lexicon. The present paper sets forward a domain based approach to semantic lexicon expansion, targeting UCREL’s Semantic Analysis System (USAS). First, an updated version of the lexicon is compared to representative corpora to ascertain areas of underrepresentation in a novel method which we call K-FLUX analysis. Second, an example set of underrepresented types are targeted for development using domain specific corpora. Collectively, the results show that some corpora are more successful than others in supplementing the existing USAS lexicon. The paper discusses the various factors that should be borne in mind when utilising the proposed method before concluding with how findings might inform future developments of the lexicon, and crucially, the semantic system on which it is based.

基于域的语义词典扩展方法

当前为语料库注释扩展语义词典的方法在本质上有些临时性，通常不提供系统化的方法来识别一个人的词典中的发展领域。本文针对UCREL的语义分析系统（USAS）提出了一种基于域的语义词典扩展方法。首先，将更新版本的词典与代表性语料库进行比较，以确定我们称之为 K-FLUX 分析的新方法中代表性不足的区域。其次，一组代表性不足的类型的示例集是针对使用特定领域语料库进行开发的。总的来说，结果表明某些语料库在补充现有 USAS 词典方面比其他语料库更成功。
