Abstract

fetched live from OpenAlex

This paper presents the results for task 2 of ShAre/CLEF 2015 eHealth Evaluation Lab. We use BM25 as our base normalization method and Pseudo Relevance Feedback to retrieve information regarding patients' health and find the best results to expand the efficiency of information retrieval system. Participants in task 2 are provided with a collection of datasets focused on health web pages. We used queries and submitted 10 runs in TREC style. The runs include the top1000 documents returned for each query. The objective of task 2 is to evaluate the effectiveness of information retrieval system and develop search engines for searching on the web looking for health related documents(1).

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.
