Summary

Team 0704mis developed a neuro-symbolic system for SemEval-2026 Task 11 Subtask 3, classifying multilingual syllogistic validity across 12 diverse languages. The system employs a neural parser to extract logical forms, which a symbolic verifier then validates against 24 Aristotelian forms using a hash lookup. Its primary innovation is a dual-view consistency test: it compares a "native" parse of the original text with a "masked" version where content terms are replaced by abstract symbols (X, Y, Z). The system proceeds only if both interpretations agree with high confidence, aiming to detect reasoning shifts between concrete and abstract contexts. This method effectively combats belief bias in LLMs, as symbol abstraction acts as a structural regularizer, compelling the model to prioritize logical relationships over semantic interference.

Key takeaway

For NLP engineers developing multilingual reasoning systems, consider integrating dual-view consistency tests to enhance logical validity and mitigate belief bias. By comparing how your model interprets arguments with both concrete and abstract content, you can ensure its reasoning focuses on structural relationships rather than semantic interference. This approach helps build more robust and reliable LLMs for complex logical tasks.

Key insights

The dual-view consistency test enhances multilingual syllogistic reasoning by enforcing content-invariant logic.

Principles

• Symbol abstraction acts as a structural regularizer.
• Dual-view comparison detects reasoning shifts.

Method

A neural parser extracts logical forms, which a symbolic verifier validates. A dual-view consistency test then compares native and masked text parses, requiring high-confidence agreement.

In practice

• Implement dual-view checks for content invariance.
• Abstract content terms to regularize LLM reasoning.
