Abstract This article provides an introduction for the collection of methodologically oriented papers comprising this Special Issue. We define the concept of epistemicity as used in descriptive linguistics and discuss notions related to it – some well-established, some more recent – such as evidentiality, egophoricity, epistemic authority and engagement. We give a preliminary overview of the different types of epistemic marking attested in the languages of the world and discuss the recent developments in the field of epistemic research focussing on methodologies for investigating epistemic marking. In the second part of the paper, we focus on the more practical side of epistemic fieldwork; the types of data that can be used in documenting linguistic expressions of epistemicity and best practices for data collection. We discuss the experimental methods that are used in the description of epistemic systems, both those developed for this particular purpose and those adapted from other types of linguistic research. We provide a critical evaluation of those materials and stimuli and discuss their advantages and disadvantages. Finally, we introduce the contributions to the Special Issue, discussing the languages studied by the authors of the contributions and the fieldwork methods they used in their research.

摘要本文为包含本期特刊的面向方法论的论文的收集提供了介绍。我们定义了描述性语言学中所使用的认识论概念，并讨论了与之相关的概念-一些公认的，最近的观点，例如证据，自善，认识权威和参与。我们对使用世界语言证明的不同类型的认知标记进行了初步概述，并讨论了认知研究领域的最新进展，重点是调查认知标记的方法。在本文的第二部分中，我们将重点放在认知实地调查的更实际方面。可用于记录认识论的语言表达和数据收集最佳实践的数据类型。我们讨论了用于描述认知系统的实验方法，包括为此目的而开发的方法以及从其他类型的语言研究中改编的方法。我们对这些材料和刺激物进行了严格的评估，并讨论了它们的优缺点。最后，我们介绍了对特刊的贡献，讨论了贡献作者所研究的语言以及他们在研究中使用的野外工作方法。
