Abstract

fetched live from OpenAlex

In this paper we compare two types of corpus, focusing on the lexical mnbiguity of each of them.The first corpns consists mainly of newspaper articles and Hterature excerpts, while the second belc)ngs to the medical domain.To conduct the study, we have used two different disambiguation tools.However, first of all, we must verify the performance of each system in its respective application domain.We then use these systems in order to assess and compare both the general ambiguity rate and the particularities of each domain.(mantitative results show that medical documents are lexically less ambiguous than tmrestrieted documents.Our conclusions show the importance of the application area in the design of NLP tools.

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.
