Abstract

fetched live from OpenAlex

The 1.1 million kilometres of roads shown on the map form a national road network that connects people and goods from one community to another in Canada and to the rest of the continent. On the map, roads are classified based on the population of the communities the roads connect; combined, the communities on the map represent 78% of the total population in 2001. Principal road corridors connect major cities with a population greater than 49 999 and major ports of entry into and out of the country. Secondary road corridors connect medium-sized populated places (of between 10 000 and 49 999) to the principal road corridor. Major roads connect the smaller-sized populated places (of between 1000 and 9999) to the principal and secondary road corridors. Minor roads connect populated places with a population less than 1000 to the principal and secondary road corridors, and to major roads. Minor roads also include roads connecting Indian Reserves. Local roads include all other roads not directly connected to the network by the population between two populated places. Winter roads serve remote and northern communities in the winter or when weather conditions permit travel.

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.

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.
