Abstract

fetched live from OpenAlex

We propose and validate a novel interleaved evaluation methodology for two complementary information seeking tasks on document streams: retrospective summarization and prospective notification. In the first, the user desires relevant and non-redundant documents that capture important aspects of an information need. In the second, the user wishes to receive timely, relevant, and non-redundant update notifications for a standing information need. Despite superficial similarities, interleaved evaluation methods for web ranking cannot be directly applied to these tasks; for example, existing techniques do not account for temporality or redundancy. Our proposed evaluation methodology consists of two components: a temporal interleaving strategy and a heuristic for credit assignment to handle redundancy. By simulating user interactions with interleaved results on submitted runs to the TREC 2014 tweet timeline generation (TTG) task and the TREC 2015 real-time filtering task, we demonstrate that our methodology yields system comparisons that accurately match the result of batch evaluations. Analysis further reveals weaknesses in current batch evaluation methodologies to suggest future directions for research.

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.
