概要	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.	Content analysis is a systematic research technique for reducing text, visual, or media material into coded categories so that patterns can be counted, compared, and interpreted. Formalised by Klaus Krippendorff in his widely cited methodology textbook (latest edition 2018), the method sits at the boundary of qualitative and quantitative inquiry: it imposes structured, replicable coding on inherently meaning-laden material.
