Abstract

fetched live from OpenAlex

6000 tweets collected at 10 am eastern standard time using NodeXL Version 1.0.1.333, from a twitter search for 'Ottawa'. Collected in the aftermath of the Ottawa Shooting at Parliament Hill. The nodexl file contains the timestamp of the tweet, the direct status url, and the text of the tweet. The csv file is the simple directed network of tweeter-tweetee. The Gephi file uses the csv file via import edges. It has been searched for modularity (at a resolution of 1.5), coloured by modules, and filtered for the five largest modules. The nodes have been resized for eigenvector centrality. I felt it important to capture the largest snapshot of tweets that I was able.

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.

Teacher imitation

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.
