Abstract
This work provides a basic overview of the significant role of lexicons in search and relevance using examples of functionality supported in a range of LexisNexis product adaptations, including the dual language Canadian products. Functionality covered includes stop words, non-stemming, equivalence, single document retrieval, word wheel suggestions/autocomplete, phrase recognition, graphical view and prompting of answer cards. The work also touches on development, curation and delivery of lexicons for consumption in the app, and provides a feel for the kinds of challenges faced in developing lexicons. The work concludes with a look at ongoing and future enhancement initiatives, including research into search engine re-platforming.
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.
