Abstract

fetched live from OpenAlex

Media analysts are challenged to acquire selections of documents that are representative of their topics of interest. Conventional search and selection processes are often constrained because of an inability to efficiently filter large amounts of potentially relevant documents and thus pose the risk of introducing bias. We describe a computer-assisted approach to increase the probability of identifying all articles relevant to a topic (in this case, marijuana), and provide an evaluation of its effectiveness in reducing bias while minimizing time expenditure. Using our system, we filtered 23,755 articles in 24.4 h. Relative to conventional processes, a substantial reduction in bias was achieved. Our system significantly reduced the risk of bias while retaining efficiency and accuracy in document selection.

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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.
