Bibliographic record
Abstract
This research paper examines how the Statistics Canada Postal Code Conversion File (PCCF) is being used by researchers. The study used a systematic search strategy to locate publications that incorporated the use of the PCCF into the underlying research process. The retrieved publications were then reviewed, and data was collected for several variables such as year of publication, type of publication, researcher’s discipline or field, and category of PCCF usage. Analysis of the results found that the Data Liberation Initiative program was definitely a factor in increasing the use of the PCCF among academic researchers. It also established that researchers from the health sciences and medical fields were the predominant users of the PCCF. With regards to the category of usage, the study has discovered that most researchers use the PCCF for the following purposes: 1) to aggregate research data to census geographic units; 2) to link research data (individual or aggregated) with the corresponding census data; 3) to determine the rural/urban geographic location of their subjects; 4) to measure distance; and, 5) to map data.
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 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.
