Abstract

fetched live from OpenAlex

Klimata pārmaiņas tiek prezentētas publiskajā diskursā, un tās veido niansēta valoda, kas atspoguļo vienu no aktuālākajiem globālajiem jautājumiem. Šī pētījuma mērķis ir analizēt atslēgvārdus un to kolokācijas Kanādas, Austrālijas un Jaunzēlandes tiešsaistes ziņu mediju rakstu diskursa korpusā par klimata pārmaiņām, apskatot tēmas un to rāmējumus. Lai sasniegtu mērķi, tiek izmantota CADS triangulācija apvienojot kvantitatīvās korpusa lingvistikas metodes ar kvalitatīvu kritiskā diskursa analīzi par tēmu ierāmēšanu. Kvantitatīvā analīze veikta darba autora veidotā korpusā ar LancsBox un Sketch Engine palīdzību. Rezultāti liecina, ka neatkarīgi no nelielām reģionālām atšķirībām viss korpus aptver ekosistēmu degradāciju, izplūdes gāzēm, ekstrēmus laika apstākļus, klimata pārmaiņu cēloņus un sekas, kas aprakstītas, izmantojot morālos rāmjus.

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.
