Key Points

This research aims to analyze the 'Signal Gap' in AI information retrieval systems, focusing on diagnostic utility at the namespace level.
Evaluated 1,320 API-collected responses across four AI models: Claude, Gemini, GPT, and Perplexity.
Focused on how dynamic retrieval systems handle signals from semantically opaque second-level domains.
Employed an open-science approach by providing a complete data and code bundle.
Identified gaps in signal processing affecting diagnostic outcomes in AI information retrieval.
Demonstrated the impact of semantically opaque domains on retrieval efficiency.
Proposed enhancements for namespace-level diagnostics within retrieval-augmented generation frameworks.

Abstract

This study investigates the "Signal Gap" in contemporary Artificial Intelligence Information Retrieval (IR) and Retrieval-Augmented Generation (RAG) frameworks. Utilizing a dataset of 1,320 API-collected responses across four frontier models (Claude, Gemini, GPT, and Perplexity), the research evaluates how dynamic retrieval systems process initial web architecture signals using semantically opaque second-level domains to isolate namespace-level diagnostic utility.The complete, open-science artifact bundle including raw datasets, prompting codebooks, and Python replication scripts is publicly hosted at: https://github.com/regalred/diagnostic-utility
