Abstract
In TREC 2013, we focus on addressing the challenges posed by the Web track using our recently proposed Quantum Language Modeling (QLM) approach for IR [1]. QLM can be considered as a dependence model for IR for its capability of representing and integrating compound term dependencies into the scoring function. Among the main properties of the model, two of them make it stand out from the literature of existing dependence models (such as MRF [3]). First, QLM does not combine scores obtained from matching single terms and from matching compound dependencies, which makes it virtually parameterless. This is quite an appealing property for an IR system, especially when a new dataset such as ClueWeb12 is released and no previous training examples can be leveraged to fine-tune important parameters. The second peculiar feature of our model is its ability to automatically fallback onto the baseline bag-ofwords score in the case that the required dependence relationship does not hold in the document. This is expected to bring improved robustness w.r.t. the baseline ranking. In the light of these considerations, the Web Track ad-hoc and robustness task seem the perfect testbeds for our model. In what follows we briefly review some of the theoretical background of QLM before delving into the description of the submitted runs and obtained results.

Full frame distilled prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
