概要	Comparative semiotic analysis examines how signs, symbols, and meaning-making systems operate across two or more contexts — such as different cultures, historical periods, media platforms, or social groups. By applying semiotic frameworks (denotation, connotation, myth, codes, paradigms) systematically across parallel corpora, researchers reveal how the same sign produces different meanings, how ideologies are encoded differently, or how symbolic structures converge and diverge across settings.	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.
