G.: Global vs. Community Metadata Standards: Empowering Users for Knowledge Exchange
Bibliographic record
Abstract
Abstract. The idea of knowledge sharing has strong roots in the education process. With the current development of the technology and moving learning material into the web environment it acquired a new dimension. Learning objects are the chunks of knowledge shared by e-learning community. Organizations and individuals are building repositories of learning objects and annotate them with metadata to describe their educational values and standardization efforts are on the way to provide a franca lingua for the educators. In this paper we describe the peer-to-peer infrastructure for sharing learning object we are building in Canada. The POOL projects builds on the three types of nodes: SPLASH is an freely downloadable application which allows individuals to create metadata and maintain their collection of learning objects, PONDs are bigger repositories of learning objects connected to the peer-to-peer network and POOL centrals increase the speed and breadth of the searches in the peer-to-peer network. The POOL project uses CanCore- a subset of the IMS metadata protocol- to describe learning objects. In the

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.
