Searching and Browsing Using RDF-Encoded Metadata: The Case of Omnipaper
Bibliographic record
Abstract
Often metadata applications concentrate on either searching or browsing. Two completely independent prototypes covering both searching and conceptual browsing (with overlapping functionality) have been built as part of the Omnipaper project: one using RDF and one using the Topic Maps family of technologies. This paper will present the full RDF prototype, with particular emphasis on the homogeneity provided by the use of RDF (together with RDF-S) in both approaches. The Omnipaper Resource Description Framework (RDF) prototype handles both these approaches and builds a coherent semantic metadata layer that may be used as a basis for all other prototypes of the Omnipaper project. As a future phase of the project, the main features to be added to the project’s final prototype will be multilinguality and personalization.
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.
