Tóm tắt	Field-based semiotic analysis is a qualitative approach that combines sustained fieldwork observation with systematic semiotic analysis of signs, symbols, and meaning-making practices encountered in a natural setting. Drawing on the social semiotic tradition of Hodge and Kress, the researcher enters a social field, records its multimodal sign systems — including visual, spatial, gestural, and textual elements — and interprets how participants use and negotiate signs to construct social meanings.	Discourse analysis is a qualitative research methodology that examines how language, communication, and power shape meaning, identity, and social reality. Developed across linguistics, sociology, and psychology (particularly by Norman Fairclough and Jonathan Potter), discourse analysis goes beyond content to analyze language use as a social practice that constitutes and reflects power relations, ideologies, and social structures.
