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.	Comparative Content Analysis applies a shared coding framework to texts, documents, or media artifacts drawn from two or more groups, contexts, time points, or nations in order to identify similarities, differences, and patterns across those units of comparison. By holding the analytical lens constant while varying the comparison unit, it reveals how meaning, framing, or discourse differs across the cases under study.
