Abstract

fetched live from OpenAlex

The rapid growth of online social networks and the recognition of their potency as a medium for the spread of misinformation has provoked a growing interest in modelling reputation and trust in multi agent networks. Intended as a novel approach towards modelling the effects a user is having on the well-being of an online community, this paper presents a method for extracting features from tree-shaped discussions and evaluates a large set of linguistic and metadata based features for their predictive ability in a data set of Reddit comments. We show that some qualities of discussion-starting comments are predictable based solely on an analysis of the discussion that follows, and outline a road-map for how learning associations between community reactions and detectable anti-social behaviour could be used to model the reputation of users.

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.

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.
