Abstract

This research presents a novel computational framework for assessing audit committee effectiveness through the integration of natural language processing, network analysis, and machine learning techniques applied to unstructured corporate governance data. Traditional approaches to evaluating audit committee performance have relied heavily on quantitative metrics such as meeting frequency, financial expertise, and independence measures, overlooking the rich qualitative information embedded in corporate disclosures, meeting minutes, and director communications. Our methodology introduces three innovative components: first, a semantic coherence scoring system that analyzes the linguistic patterns in audit committee charters and meeting discussions to assess procedural rigor; second, a temporal network analysis framework that maps the evolution of information flow between audit committees and management over time; and third, a predictive model that identifies subtle patterns in committee composition and interaction dynamics that correlate with financial reporting quality. We apply this framework to a comprehensive dataset of SP 500 firms over a ten-year period, revealing previously undetected relationships between specific communication patterns and financial restatements. Our findings demonstrate that committees exhibiting high semantic diversity in their discussions and maintaining balanced information networks with management show significantly lower incidence of financial misreporting, even when traditional quantitative metrics suggest comparable effectiveness. This research contributes to both corporate governance theory and computational social science by providing a more nuanced, data-driven approach to understanding how governance mechanisms actually function in practice, moving beyond structural characteristics to capture the dynamic processes that underlie effective oversight.
