Abstract

fetched live from OpenAlex

Adaptive indexing is an alternative to the self-tuning methods. It is especially useful in the scenario of unpredictable workload, and there is no idle time to invest in index creation. The authors present their ongoing work on a new realistic adaptive indexing that transforms the previous data crawling offline approach to a data-driven online approach. The proposed approach consists of three tasks: topic prediction, resource selection, and results combination and ranking. They work simultaneously to retrieve highly relevant results to the user's query in real time. To make the index highly refreshed and up-to-date, they collected data from highly prominent resources (e.g., Facebook, Twitter, Wikipedia, etc.). The empirical results showed that the proposed model is better than the traditional models that work offline and spend hours or days for building the index in different periods. In addition, the experiments showed that the training results are highly relevant for adhoc and diversity tasks.

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.
