Abstract

fetched live from OpenAlex

We analyze the effect of different types of online and offline ties – acquaintanceship, advice, and co-authorship – on researchers’ productivity and influence. Unlike static studies of networked work, we look at how changes in these networks affected researchers’ performance and influence. Using the number of publications as an indicator of productivity and the number of citations as an indicator of influence, we investigate when researchers were more productive and influential. We study whether their networks were cohesive, if the researchers were central in their networks or linked to central players, and whether their work had more opportunities to be disseminated through diverse, non-redundant ties. Although the connectedness of their networks was positively associated with the researchers’ productivity, it was the non-redundant effective size of the networks that was positively associated with the researchers’ influence.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
