Tóm tắt	Multiple case-based semiotic analysis is a qualitative research design that applies semiotic frameworks — the systematic study of signs, codes, and meaning-making — across two or more purposively selected cases. By combining the comparative logic of multiple case study research with the interpretive tools of semiotics (structural, Peircean, or Greimasian), it enables researchers to uncover how meaning is constructed and varied across distinct cultural, organisational, or communicative contexts.	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.
