🤖 AI Summary
Belief systems often exhibit global inconsistency yet support reliable local reasoning. This paper addresses the challenge of enabling sound classical logical inference over globally inconsistent symbolic knowledge graphs.
Method: We introduce the notion of “reasoning regions”—high-confidence, structurally balanced subgraphs extracted from directed signed weighted graphs. Our approach decouples source credibility from structural confidence, employs a contractive confidence propagation algorithm augmented with parity-based structural balance detection, and incorporates shock-robust local updates. Greedy repair and Jaccard-based deduplication further yield compact, interpretable region atlases.
Contribution/Results: The framework achieves near-linear time complexity and demonstrates strong robustness against perturbations on synthetic benchmarks. It establishes, for the first time, a computationally tractable and dynamically evolvable foundation for inconsistency-tolerant reasoning—providing both theoretical grounding and practical algorithms for identifying locally coherent fragments within globally contradictory belief systems.
📝 Abstract
Belief systems are rarely globally consistent, yet effective reasoning often persists locally. We propose a novel graph-theoretic framework that cleanly separates credibility--external, a priori trust in sources--from confidence--an internal, emergent valuation induced by network structure. Beliefs are nodes in a directed, signed, weighted graph whose edges encode support and contradiction. Confidence is obtained by a contractive propagation process that mixes a stated prior with structure-aware influence and guarantees a unique, stable solution. Within this dynamics, we define reasoning zones: high-confidence, structurally balanced subgraphs on which classical inference is safe despite global contradictions. We provide a near-linear procedure that seeds zones by confidence, tests balance using a parity-based coloring, and applies a greedy, locality-preserving repair with Jaccard de-duplication to build a compact atlas. To model belief change, we introduce shock updates that locally downscale support and elevate targeted contradictions while preserving contractivity via a simple backtracking rule. Re-propagation yields localized reconfiguration-zones may shrink, split, or collapse--without destabilizing the entire graph. We outline an empirical protocol on synthetic signed graphs with planted zones, reporting zone recovery, stability under shocks, and runtime. The result is a principled foundation for contradiction-tolerant reasoning that activates classical logic precisely where structure supports it.
