Σύνοψη	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.	Critical Discourse Analysis (CDA) is a qualitative method that examines how language in texts and talk constructs, sustains, and challenges relations of power, ideology, and social inequality. Drawing on linguistics, social theory, and critical philosophy, CDA treats discourse not merely as communication but as social practice — a site where dominance is reproduced and where resistance can be articulated. Developed in the late twentieth century by Norman Fairclough, Teun van Dijk, and Ruth Wodak, among others, CDA is applied to political speeches, media texts, policy documents, educational materials, and institutional interactions.
