Abstract

fetched live from OpenAlex

Food fraud occurs when a food product is illegally sold with the intention of misleading consumers, usually for economical gain. Food crime consists of any criminal activity that affects safety or authenticity of food; which can include product mislabelling, species substitution, misbranding, counterfeiting, dilution and adulteration. Seafood sample data was compiled from various studies done in Canada that reported seafood mislabelling over the past decade from 2008 to 2019. Product substitution can occur when the species on the fish list that is identified based on the label (common) market name does not match the BOLD identified species (j). Product substitution occurs due to various reasons such as a high demand for a limited supply, a greater profit margin, a growth in international trade of processed seafood, lack of strict seafood labelling and naming regulations, etc. Retailers and consumers are also exposed to health and environmental risks.

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.
