Ein ganzheitlicher Ansatz zur Digitalisierung und Extraktion von Metadaten in Videoarchiven
Bibliographic record
Abstract
Dem standigen Wachstum von Multimediaarchiven mit Automatisierung zu begegnen erfordert neue Ansatze und Losungen bei der Extraktion und Verwaltung von Metadaten. Dazu wurden die Frameworks AMOPA und Imtecs entwickelt, um Informationen uber den Inhalt der Multimediadaten und die technischen Randbedingungen ihres Einspielvorganges zu extrahieren und den nachfolgenden Stationen des Workflows zur automatischen Steuerung ihrer Arbeitsschritte zur Verfugung zu stellen. Im Archiv angewandt, ermoglichen sie sowohl umfangreichere und komplexere als auch spezifischere Suchen und Anfragen.
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 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.
