Abstract

fetched live from OpenAlex

Due to the rapid growth of e-commerce (and other Internet-related technologies), many companies want to migrate their information systems to the net-centric environment. We are proposing a toolkit (Varlet/Babel) that helps the user to achieve this goal. This is accomplished in two stages. In the first stage, a database schema is obtained and refined, then an XML description for the database schema is generated and used to wrap access to the information system. In this paper, we focus on the second stage and describe the methods that are used to create a mapping between the generated schema and a standard (interchange) schema and to make a second wrapper around the information system.

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.
