University of Ottawa's Contribution to CLEF 2005, the CL-SR Track
Bibliographic record
Abstract
We present the participation of the University of Ottawa in the Cross-Language Spoken Document Retrieval task at CLEF 2005. In order to translate the queries, we combined the results of several online Machine Translation tools. For the Information Retrieval component we used the SMART system, with several weighting schemes for indexing the documents and the queries. One scheme in particular lead to better results than other combinations. We present the results of the submitted runs and of many unofficial runs. We compare the effect of several translations from each language. We present results on phonetic transcripts of the collection and queries and on the combination of text and phonetic transcripts.
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.
