Abstract: In this paper we explore tool support for categorical coding of verbal and chat
data. We consider tool support for manual coding, automatic coding by learning
algorithms, and derive at a socio-technical approach in which human coders and learning
algorithms together address the coding task. Given that a literature study suggests
researchers devise, adapt and refine a wide variety of coding schemes, a categorization
support system should handle and accommodate user defined coding schemes. Based on
these ideas a prototype of the ChatIC tool was developed and evaluated with three coding
schemes. For two coding schemes a sufficient inter-rater agreement between a human
coder and the learning algorithms was reached.
Introduction
This paper explores the opportunities of tool support for categorical coding of verbal data and
messages obtained from collaborative chats. Our main motivation is of a practical nature. More and more
interaction protocols obtained from computer mediated communication (CMC) become available, from
various (on-line) sources and on various domains. Behavioral scientists who want to study this data often
devise and apply their own coding schemes, and given the lack of special purpose coding tools they are
