Abstract

fetched live from OpenAlex

Resource Description Framework (RDF) is a data model that represents information about web resources using triples.Triples represent data at the atomic level using three components: subject, predicate and object.The structure of RDF data is defined by a schema language RDFS.RDF data storage can be classified into five categories: Native, Relational, Object-Oriented, Object-Relational and Expert Systems.Of these, Native and Relational have been the dominant approaches.The problem with all current RDF storage approaches is that none adequately represent the features of RDFS with the schema of their underlying storage architecture.In this thesis, the problem is addressed using Information Network Model Database (INMDB) which attempts to better represent RDFS as database schema.To support our claim, we store the English version of the DBPedia RDF dataset in INMDB.The results show that INMDB offers a more representative way to store and query structured RDF data.

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.
