Tóm tắt	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 Visual Analysis is a qualitative research design that systematically examines and compares visual materials — photographs, videos, artworks, advertisements, or digital images — across two or more cases, groups, time points, or contexts. By applying a consistent analytical framework to multiple visual corpora, the approach reveals similarities, differences, and patterns that would remain invisible when studying a single set of images alone.
