概要	Digital Semiotic Analysis applies the classical study of signs and meaning-making to content produced and circulated in digital environments. It examines how signifiers — words, images, icons, sounds, emojis, hyperlinks, and interface conventions — create meaning within digital texts such as websites, social media posts, memes, and online advertisements. The method draws on Saussurean dyadic semiotics and Peircean triadic semiotics, extended by Roland Barthes's connotation and myth framework and by contemporary multimodal semiotic theory developed for screen-based media.	Semiotic analysis is a qualitative method for interpreting how signs — words, images, sounds, gestures, and objects — produce and communicate meaning within a cultural context. Drawing on the structural linguistics of Ferdinand de Saussure and the triadic sign theory of Charles Sanders Peirce, and popularised as a research tool by Roland Barthes, semiotics moves beyond surface denotation to expose the connotative and ideological meanings embedded in texts and visual culture.
