概要	Digital Conversation Analysis (DCA) applies the systematic, turn-by-turn analytical procedures of Conversation Analysis (CA) to digital and computer-mediated interactions — including chat logs, social media threads, instant messages, and online forums. Rooted in the foundational CA framework of Sacks, Schegloff, and Jefferson, DCA adapts classical concepts such as turn-taking, adjacency pairs, and sequential organisation to account for the asynchronous, multimodal, and textual character of online communication.	Conversation Analysis (CA) is a qualitative research method that examines the fine-grained sequential structure of naturally occurring talk and social interaction. Developed by sociologists Harvey Sacks, Emanuel Schegloff, and Gail Jefferson in the 1960s and 1970s, CA investigates how participants in a conversation accomplish social actions — such as invitations, refusals, or diagnoses — through the precise moment-by-moment organisation of their talk, including turn-taking, sequence structure, repair, and recipient design.
