خلاصه	Interpretive semiotic analysis is a qualitative method that examines how signs — words, images, symbols, gestures, and sounds — produce meaning within specific social and cultural contexts. Drawing on Saussurean semiology and Barthesian cultural analysis, the approach moves beyond surface-level description to uncover the layered, context-bound meanings that sign systems generate. It is widely used in media studies, communication, education, marketing, and cultural research to reveal how representations shape social reality.	Interpretive discourse analysis is a qualitative approach that examines how language constructs social realities, identities, and meanings within specific contexts. Operating from an interpretivist epistemology, it treats texts and talk not as transparent windows onto the world but as active sites where meaning is negotiated, and it seeks to understand those meanings from the perspective of participants situated within their social and cultural worlds.
