Critical Discourse Analysis of News Reports on China’s Bullet-Train Crash
Bibliographic record
Abstract
The purpose of critical discourse analysis is to study the relationship between language and the ideology embedded in the text of the dialectical aspect. Critical discourse analysis is an emerging method of discourse analysis, which assimilates the results of multi-disciplinary scientific research in linguistics, psychology, sociology, media studies and so on. It attaches importance to all the non- literary discourses, but it takes news discourses as its main research object. Based on Halliday’s three metafunctions, critical discourse analysis in this thesis is done on the basis of news reports about “China’s bullet-train crash” collected from Western media. Fairclough’s three-dimensional model is adopted in the analysis, including description, interpretation and explanation. The aims of the thesis are to reveal how the Western media construct China’s image by using the different linguistic tools, explore the relationship between this constructing mode and big social cultural context, and thus unhidden the ideology embedded behind the social news reports.

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.
