概要	Critical semiotic analysis is a qualitative method that examines how signs — words, images, gestures, sounds — construct and naturalise ideological meanings. Drawing on Roland Barthes's distinction between denotation and connotation, and on critical social semiotics developed by Kress and van Leeuwen, the approach moves beyond surface-level description to expose how texts reproduce or challenge power relations, cultural norms, and dominant ideologies.	Critical content analysis is a qualitative approach that examines texts, media, and documents not merely for manifest meaning but for how they construct, reinforce, or contest relations of power, ideology, race, gender, and class. Grounded in critical theory traditions, it asks whose interests a text serves, what voices are silenced, and how language and representation naturalise dominant worldviews. It combines systematic analytic rigour with an explicitly emancipatory or transformative research stance.
