概要	Digital Critical Discourse Analysis (Digital CDA) is a qualitative research approach that applies the theoretical and methodological tools of Critical Discourse Analysis to digital and online communicative contexts. It examines how language, multimodal elements, and digital affordances are mobilized in online spaces to produce, reproduce, or contest power relations, ideologies, and social inequalities. Drawing on traditions established by Fairclough, Wodak, and van Dijk, Digital CDA treats digital texts — from social media posts to comment threads and websites — as sites of ideological struggle shaped by the platforms that host them.	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.
