摘要	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.	Content analysis is a systematic research technique for reducing text, visual, or media material into coded categories so that patterns can be counted, compared, and interpreted. Formalised by Klaus Krippendorff in his widely cited methodology textbook (latest edition 2018), the method sits at the boundary of qualitative and quantitative inquiry: it imposes structured, replicable coding on inherently meaning-laden material.	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.
