概要	Metaphor Analysis is a qualitative method that identifies, classifies, and interprets the metaphors embedded in language to reveal how speakers and writers conceptualise experience, construct meaning, and exercise ideological influence. Grounded in Lakoff and Johnson's Conceptual Metaphor Theory, it treats metaphor not as a literary decoration but as a fundamental cognitive structure — ARGUMENT IS WAR, TIME IS MONEY — that shapes how people think, reason, and act. It is widely applied in psychology, education, political discourse, health communication, and organisational research.	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.	Grounded Theory (GT) is a systematic qualitative research methodology in which theory emerges directly from data through iterative analysis, rather than being imposed before data collection. Developed by Barney Glaser and Anselm Strauss in 1967, GT prioritizes generating explanatory frameworks grounded in evidence.
