Regex in R for Multimodal Analysis

Many researchers in the fields of Conversation Analysis and Interactional Linguistics painstakingly elaborate transcripts and manually implement annotations in ELAN, a software for multimodal annotation. Few researchers, however, seem to know how to post-process this immensely valuable data in a way that allows synthesis, aggregation, transformation, large-scale analysis and visualization. This workshop aims to present some solutions for these tasks implemented in R and based on Regular Expression (or regex), a syntax used to match, select, edit, and extract data and to reshape data frames based on regularities (patterns) in the data.

The full-day workshop will cover these topics:

– Basics of R and regex (Crash Course)

– Convert (multimodal) transcripts to R data frames to make them machine-readable

– Analyze (multimodal) transcripts in R data frames

– Export and structure ELAN annotations in R data frames

– Analyze and visualize ELAN annotations in R data frames

The workshop is open to beginners and more experienced users of R. To facilitate a running start for everybody, the workshop will start with a crash course on the key syntactic elements of regex and some key R functions before we turn to using them for Multimodal Analysis. The workshop aims for maximum relevance to the participants: participants are encouraged to articulate to the instructor what special tasks they wish to achieve with their data prior to the workshop (no later than 9 May, 2025). Concrete solutions to these tasks could be discussed during the workshop.

The maximum number of participants is 25; the registration deadline is 9 May, 2025. To register (and, if you want, to share your data) please contact: chrisruehlemann@gmail.com
