Deep classification: pornography, bibliographic access, and academic libraries
Bibliographic record
Abstract
This study examines the mainstreaming of pornography in the context of current economic, popular culture, and academic trends. As pornography becomes part of popular culture, it simultaneously becomes an area of focus for academics and therefore presents particular challenges for college and university libraries. Both physically and conceptually, academic libraries must find a place for pornography on the shelves and in the array of knowledge structured by bibliographic access systems. This study looks at how the variety of issues, concepts, and genres of pornography considered in academic discourse could be accommodated within access systems by examining the way in which the adult industry itself classifies pornographic films. Specifically, the terms used by the adult industry to classify these films could be grouped within newly developed categories. The identification of the categories would not be predicated on characteristics of porn films alone. Instead, the categories would encompass specific topics, concepts, and subject areas that connect pornography to mainstream culture. Using classifications from four different adult industry sources, four sample categories are presented that could serve as a model for how pornographic concepts could be accommodated within existing bibliographic access systems.

Full frame machine prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
