From Text to Scheme: Problems in Identifying Arguments from Expert Opinion
Bibliographic record
Abstract
We show how to solve common problems in identifying arguments from expert opinion, illustrated by five examples selected from The Economist. Our method started by intuitively identifying many appeals to alleged experts in The Economist and comparing them to the argumentation scheme for argument from expert opinion. This approach led us to (i) extending the existing list of possible faults committed when arguments from expert opinion are performed and (ii) proposing the extension of the list of linguistic cues that would allow analysts to identify arguments from expert opinion. Our ultimate aim is to help argument identification by argument mining connect better with techniques of argument analysis and evaluation.

Full frame machine prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
