Subclaims¶

q2 i? The coauthorship network of 22 workshop organizers contained 2,197 authors and over 4,000 publications, with Louvain detection yielding six communities and 80% of nodes in the largest three. → coauth-1 q2 i? The main clusters reflect distinct lineages: one tied to Carnegie Mellon University and intelligent tutoring systems, one centered on writing and literacy technology, and one connected to engineering areas such as image processing. → coauth-2

q2 · i? · associational · r1

Coauthorship network analysis in the R package Bibliometrix over publications of 22 workshop organizers retrieved from OpenAlex; only three of six workshops were indexed. The analysis "resulted in six total communities, with the majority (80%) of nodes falling into the largest three."

"The network had a total size of 2,197 authors and over 4,000 publications. We used Louvain community detection technique (Blondel et al., 2008) to create clusters of researchers based on their shared publications."

coauth-2¶

q2 · i? · associational · r1

Qualitative characterization of the three main clusters from the same coauthorship analysis: Community 2 tied to "Carnegie Mellon University", Community 3 focused on "technology for writing and literacy education", and Community 1 linked to organizer Richard Baraniuk's engineering focus such as "image processing".

"Many researchers in this group, or closely connected to it, had strong ties to Carnegie Mellon University."

• Removing the workshop's coauthorship edges increased average path length and network diameter, indicating the workshop publications bridge otherwise separate researcher groups — related
• Platform-enabled experimentation research draws on multiple intellectual lineages, including intelligent tutoring systems, formative feedback, and exemplar platforms like ASSISTments — related
• The DLP-as-research-infrastructure community is small and fragmented: the DLP-focused cluster was one of five bibliographic-coupling communities and only 20.6% of filtered papers — related
