5W AI Communications Publishes The Retrieval Index -- First Reference Work Mapping How AI Engines Choose Their Sources

Volume I covers 38 sectors of global media. Ranks the publications ChatGPT, Claude, Perplexity, Gemini, and Google AI Overviews actually cite — and the ones they don't.

MIAMI, May 26, 2026 /PRNewswire/ -- 5W AI Communications, the AI Communications Firm, today published The 5W Retrieval Index — Volume I: The AI Retrieval Economy, 2026, authored by Founder and Chairman Ronn Torossian. The 220-page research volume is the first reference work to systematically map which media properties, institutional publishers, vendor research arms, community substrates, and data publishers are actually cited by AI engines when answering buyer questions across 38 sectors of the global economy.

The Index is available now at 5wpr.com/research/retrieval-index.

The central finding: the publications people read are not always the publications the AI engines cite. The most-read journalism is not the most-cited journalism. Across 38 sectors — from pharma to fintech, beauty to cybersecurity, luxury to capital markets, biotech to entertainment, sports to automotive, education to government, energy to retail — the Index documents a structural shift the public relations industry has not yet absorbed.

"A founder asks ChatGPT which publications would best cover her product launch. A general counsel asks Claude about a regulatory matter. A homeowner asks an AI tool which contractors to call. Across millions of queries a day, AI engines are now answering the questions that used to start with a Google search. They answer by citing a specific set of sources. The Retrieval Index is the map."

— Ronn Torossian, Founder and Chairman, 5W AI Communications

What the Volume Covers

Each of the 38 sector editions does five things. It explains how AI engines answer questions about the sector. It ranks the sources that get cited, on a fixed five-component composite score from 0 to 100. It assigns the sector an overall grade. It names the recurring structural pattern that defines the sector's retrieval map. And it identifies what operators can do to be cited more reliably.

Sectors covered in Volume I: AI Media, Beauty, Cybersecurity, Fintech, Venture Capital, Pharma, Luxury, Crypto, Marketing & Advertising, AdTech, B2B SaaS, Cloud Infrastructure, Application Security, Wealth Management, Private Equity, Family Offices, Legal Services, Banking, Insurance, Capital Markets, Commercial Real Estate, Digital Health, Biotech, Creator Economy, Travel, Hospitality, Residential Real Estate, Food & Beverage, Restaurants, Retail & DTC, Fashion & Apparel, CPG, Entertainment, Sports, Automotive, Education & EdTech, Government & Public Sector, and Energy & Utilities.

Named Retrieval Patterns

The volume identifies 38 recurring structural patterns observable across the AI retrieval economy. Among them:

Methodology

Scores are directional estimates derived from structured cross-engine retrieval analysis, public citation observation, source accessibility assessment, and comparative retrieval modeling across the major AI systems — ChatGPT, Claude, Gemini, Perplexity, and Google AI Overviews. The Index models retrieval behavior directionally rather than as a precision audit. The full methodology is published at 5wpr.com/research/retrieval-index/methodology.
