Abstract

fetched live from OpenAlex

We are interested in the creation of Peer-to-Peer systems that consist of autonomous databases coordinated by event-condition-action rules. Such systems could be used for the exchange of information among peers who do not desire wholesale integration of their respective databases. For example, a patient's history could be automatically updated in the database of her family doctor whenever she is admitted in a hospital. Conversely, the hospital database may automatically get medical data on patients. The thesis presents a rule language and a rule execution model designed for the creation and the distributed evaluation of rules in a P2P multi-database system. A primary objective in the design of the rule mechanism has been the minimization of communication load among peers. It is assumed that all peer databases are relational. The thesis reports on a prototype implementation of the basic features of the proposed rule mechanism and illustrates its applications with examples.

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 distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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.
