Abstract Corpus-based studies of specialized registers typically sample texts using random methods as far as possible, but they disregard social characteristics of the speakers/writers. In contrast, in corpus-based studies of conversation and quantitative sociolinguistic studies, sampling is more typically designed to optimize social representation. To our knowledge, this study is the first to compare linguistic outcomes from random versus sociolinguistic sampling in a specialized register. Our data comes from the biographical radio chat show, Desert Island Discs (DID), at different points in time. We constructed two versions of a DID corpus: a sociolinguistic judgment sample based on guest demographics, and a random sample. We compare grammatical usage between them using an inductive (‘key POS-tags’) method and close manual analysis, uncovering some evidence of significant grammatical differences between the samples and differing patterns of diachronic change. We discuss the implications of our research for corpus design, representativeness and analysis in specialized registers.

摘要 基于语料库的专业语域研究通常尽可能使用随机方法对文本进行抽样，但他们忽略了说话者/作者的社会特征。相比之下，在基于语料库的对话研究和定量社会语言学研究中，抽样通常旨在优化社会表征。据我们所知，这项研究是第一个比较专业语域中随机抽样与社会语言抽样的语言结果的研究。我们的数据来自不同时间点的传记广播聊天节目“荒岛唱片”(DID)。我们构建了两个版本的 DID 语料库：基于客人人口统计的社会语言判断样本和随机样本。我们使用归纳（“关键词性标签”）方法和密切的手动分析来比较它们之间的语法用法，揭示了样本之间显着语法差异和历时变化的不同模式的一些证据。我们讨论了我们的研究对专业语料库中的语料库设计、代表性和分析的影响。
