Abstract

fetched live from OpenAlex

Land is the base of survival and development of human being. Limited land resource is the power that stimulates us to intensively use land. According to the connotation of intensive use of construction land, we select 5 indices which are cogent and effective. Then through Data Envelopment Analysis(DEA), we estimate the different efficiency of intensive use of construction land in China and its 31 provincial regions. The result is that in these 31 regions, only Heilongjiang and Shanghai are efficient, and the other DMUs are inefficient. At last, based on this result, we provide some relevant advices.

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.
