A “multimodal digital semiotics” approach, involving the development and use of interactive digital media technology, mathematical techniques of analysis and scientific visualization for modeling and analyzing multimodal phenomena, is demonstrated through the analysis of an interview between a climate scientist and a climate denialist on Fox News. Prototype software for multimodal analysis and network visualizations are used in combination with Allen's interval algebra to model multimodal semantic data and identify significant patterns based on temporal relationships between different semiotic choices. The resulting semantic patterns reveal combinations of semiotic choices that were drawn upon by the different speakers during the interview, accounting for how the climate denialist emerges as the dominant and convincing interviewee. Such an approach combines the objectivity of mathematical modeling and scientific visualization with the interpretive power of Halliday's systemic theory.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
