Conversation analysis
Conversation analysis is a linguistic system developed using linguistic principles to understand the structure of any given "text". Texts in this context are usually transcriptions, whose participants are referred to as members. Conversation analysis evolved from Ludwig Wittgenstein's philosophical notions of language.The use of Conversation analysis as a system for understanding the rules members apply in texts was pioneered by Harvey Sacks. Sacks died early in his career, but his work was championed by others in his field.
Today conversation analysis enjoys widespread usage across many diciplines ranging from linguistics to statistics. In particular, the fields of discursive psychology and discourse analysis use conversation analysis as a framework for measuring socio-psychological phenomena.
