Abstract
The author introduces how to perform statistical analysis of textual data in an automated and effective way by utilizing a free software “KH Coder” in the field of linguistics. First, the major functionalities and philosophy of the KH Coder are explained to provide an overview of the software. The KH Coder was originally developed to perform analysis in the field of sociology or social research rather than that of linguistics. Because the KH Coder was developed in a different discipline, this overview will help with understanding its function and how to actually use it as applied to linguistics. Second, procedures for customizing the KH Coder settings are described to demonstrate how it will be more useful in the field of linguistics. For example, with the default settings, the KH Coder ignores all function words such as particles or auxiliary verbs, and focuses only on content words. To analyze function words, the parts of speech setting needs to be modified. Additionally, we can modify the word extraction setting to manually correct morphological analysis results to increase their accuracy.
