Scientific peer reviews frequently contain conflicting expert judgments, and the increasing scale of conference submissions makes it challenging for Area Chairs and editors to reliably identify and interpret such disagreements. Existing approaches typically frame reviewer disagreement as binary contradiction detection over isolated sentence pairs, abstracting away the review-level context and obscuring differences in the severity of evaluative conflict. In this work, we introduce a fine-grained formulation of reviewer contradiction analysis that operates over full peer reviews by explicitly identifying contradiction evidence spans and assigning graded disagreement intensity scores. To support this task, we present RevCI, an expert-annotated benchmark of peer-review pairs with evidence-level contradiction annotations with graded intensity labels. We further propose IMPACT, a structured multi-agent framework that integrates aspect-conditioned evidence extraction, deliberative reasoning, and adjudication to model reviewer contradictions and their intensity. To support efficient deployment, we distill IMPACT into TIDE, a small language model that predicts contradiction evidence and intensity in a single forward pass. Experimental results show that IMPACT substantially outperforms strong single-agent and generic multi-agent baselines in both evidence identification and intensity agreement, while TIDE achieves competitive performance at significantly lower inference cost.

Local search systems must determine WHERE to search before retrieving results. We present OmniQUM, a fine-tuned 7B model for generative location disambiguation: given a query and geo-coordinates, it produces a disambiguated location target and bounding box decision in a single pass. Unlike NER + gazetteer pipelines, it jointly reasons over query intent and geographic context. We train across 14 locales and 7 languages with a failure-driven agentic pipeline generating targeted samples iteratively. We introduce expanding donut retrieval, sampling candidates from concentric, slightly overlapping rings to improve recall over naive bounding box retrieval. On 52K queries reflecting real traffic distribution, we achieve F1 0.94 on location disambiguation and 32.7% retrieval recall improvement, surfacing 86K additional relevant POIs. Deployed with vLLM and bf16 on dual GPUs, we achieve sub-150ms TM95 latency at 0.12× baseline cost, with 7–38% cache hit rates.
