सारांश	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.	Case study research is a qualitative research design that investigates a specific phenomenon, individual, group, organisation, or event in depth within its real-world context. Systematised by Robert K. Yin in 1984, it supports single-case and multiple-case designs and draws on multiple data sources — interviews, observation, documents, and artefacts — to build a rich, contextualised account of a bounded unit.
