Maddies NLP at the FinEval 2026: Proposition-Aware Tagged Reasoning for Japanese Implicit Communication Recognition

Madhav Kapoor, Aditya Channa, Jastej Singh


Abstract
We describe our system for the FinNLP 2026 Japanese Financial Implicit Communication Recognition (JF-ICR) shared task. The task requires assigning one of five ordinal commitment and refusal labels to a Japanese investor-relations question and company response. Our final system uses the 30.7B-parameter OpenRouter model ‘google/gemma-4-31b-it‘ in a two-stage, proposition-aware workflow. A label-blind first stage extracts tagged evidence for the target proposition, modality, actor and controllability, negation scope, conditionality, and institutional anchors. A second stage re-reads the original Japanese with this evidence and emits the final label before an optional rationale. On 253 labeled development examples, the system reaches 60.08% accuracy versus 56.92% for our earlier single-call control, with no invalid labels. The frozen submission scores 93.33% (14/15) publicly and 94.29% (33/35) privately. Deeper decision trees, latent-score mapping, and parallel judging all reduce accuracy, favoring compact decomposition with strict output control.
