Structural Coherence Metrics for Long-Form AI Research: Beyond Paragraph-Level Quality

Structural Coherence Metrics for Long-Form AI Research: Beyond Paragraph-Level Quality #

This article introduces a framework for measuring document-level coherence in AI-generated research papers, focusing on argument flow, section interdependency, and logical consistency across multiple sections.

Key Components

• Argument Flow: Quantifies transition logic between claims.
• Section Interdependency: Maps directed dependencies among sections.
• Logical Consistency: Detects contradictions via rule-based validation.

Code Example

def compute_coherence(paragraphs):
    # Placeholder implementation
    scores = [0.8, 0.75, 0.85]
    return sum(scores) / len(scores)

Data Charts The manuscript anticipates visualizations of interdependency graphs and coherence score distributions. These charts will be generated by the pipeline and stored in charts_dir for embedding. Placeholder commentary: use color gradients to indicate confidence and clear node labels for readability.
