Abstract

fetched live from OpenAlex

Data_A shows the amounts of obvious missing flows that need to be added to each activity in ecoinvent v3.10. Data_B shows the initial and final mass estimates of products in the ecoinvent database while Bel shows the final and initial mass estimates for elementary flows. Data_Gamma shows which activities lack end-of-life flows for capital uses. Data_Eprod shows which products have been disaggregated into which alternatives while Data_Eact shows which disaggregated products interact with which (disaggregated) activities. El_flow_bounds gives the minimal and maximal mass for every elementary flow. Product_pounds gives the minimal and maximal mass bounds for every product.

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.
