Analysis of Textual data for integrating an automated coding environment system and building a system to monitor the quality of its results
Bibliographic record
Abstract
Actually Italian National Institute of Statistics (ISTAT) is evaluating the c hance of using a software for automatic coding of textual responses to questions about occupation, education level etc.. The system chosen is ACTR (Automated Coding by Text Recognition) developed by Statistics Canada. A first test of the system was carried out with data from the quality survey on Population Census of year 1991. The good results obtained led to p erform a further analysis with textual data from Labour Forces Survey. The purpose was to d efine a standardised p rocedure which to refer when ACTR is used d uring a survey instead o f a manual coding. In particular, the analysis carried out in this paper aims at developing a procedure to integrate the basic automated coding environment and to build up a system to monitor the quality of the results of automated coding.

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.
