Abstract

fetched live from OpenAlex

Utilizing the UN Comtrade database's iron ore trade data from 1991 to 2020, this study employs complex network theory to construct a global iron ore trade network. The trade pattern is analyzed using network parameters, such as average degree, average clustering coefficient, heterogeneity, and centrality index. Findings reveal a highly heterogeneous global iron ore trade network dominated by a few core countries, exhibiting extreme fragility. China, Japan, and South Korea hold significant import market positions, with Asia's influence growing. Australia and Brazil dominate the export market, while Canada and South Africa demonstrate promising export potential. The Netherlands, the United States, Germany, and Turkey serve as iron ore trading hubs, playing a crucial role in resource supply security.

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 distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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.
