概要	Digital document analysis is a qualitative method for systematically locating, appraising, and interpreting documents that exist in digital or online form — including websites, emails, institutional reports, policy files, social media content, and digital archives. It applies the established logic of document analysis to born-digital and digitised sources, enabling researchers to examine meaning, discourse, and institutional practice embedded in contemporary digital texts without recruiting participants.	Digital ethnography is a qualitative research method that adapts traditional ethnographic fieldwork to online and digitally mediated settings. Drawing on sustained participant observation, document collection, and sometimes interviews, the researcher immerses themselves in one or more digital communities — social media platforms, forums, gaming spaces, or messaging groups — to understand how culture, identity, and social practice are constructed through digital interaction. The approach recognises that online spaces are not merely reflections of offline life but distinctive sites of cultural production in their own right.	Discourse analysis is a qualitative research methodology that examines how language, communication, and power shape meaning, identity, and social reality. Developed across linguistics, sociology, and psychology (particularly by Norman Fairclough and Jonathan Potter), discourse analysis goes beyond content to analyze language use as a social practice that constitutes and reflects power relations, ideologies, and social structures.
