Hi Friends,

Even as I launch this today ( my 80th Birthday ), I realize that there is yet so much to say and do. There is just no time to look back, no time to wonder,"Will anyone read these pages?"

With regards,

AI's Reality Check: Long-Tail Answers

AI's Reality Check: Long-Tail Answers

The world of Artificial Intelligence, for all its marvels, occasionally confronts us with moments when users, as the saying goes, 'lose touch with reality.' This isn't a flaw in the AI itself, but rather a profound illustration of how critical reliable information retrieval and precise understanding truly are. I've often pondered these challenges, especially in light of my own thoughts on managing vast datasets.

I remember years ago, I shared a note with Shalaka (shkathapurkar@paypal.com) about optimizing our search capabilities for millions of keywords, envisioning a single URL topping search results for specific job advertisements Long Tail Jobs. The essence was to move beyond conventional search, to index and access information with a granularity that anticipated diverse user queries, even what we called 'long tail' keywords. I proposed utilizing the Google Search Appliances API and comparing its efficacy with our existing ISYS database for resume searches, aiming for faster, more accurate results. My intention was always to create a system where information, no matter how vast, was meticulously indexed and readily retrievable through precise keywords.

The core idea I wanted to convey then, and one that resonates deeply today, is this: take a moment to notice that I had brought up this thought or suggestion on the topic years ago. I had already predicted the challenge of efficiently navigating immense data and had even proposed a solution at the time—a robust, keyword-driven indexing system. Now, seeing how things have unfolded with AI models sometimes producing plausible-sounding but inaccurate information, it's striking how relevant that earlier insight still is. Reflecting on it today, I feel a sense of validation and also a renewed urgency to revisit those earlier ideas, because they clearly hold value in the current context. The very concept of AI 'losing touch with reality' underscores the critical need for foundational systems that prioritize verifiable information and accurate contextual retrieval, much like the precise keyword indexing I advocated for.

It's not just about generating answers; it's about grounding those answers in a verifiable, meticulously indexed reality. My conversations with Suman (suman@anyscale.com) about generating questions from documents for my digital avatar also touched upon this need for structured, searchable knowledge Generating QUESTIONS from my Documents. Whether it's a person asking a question or an AI synthesizing an answer, the underlying demand for accurate, accessible information remains paramount. The quest for perfect retrieval continues, and the principles of intelligent indexing remain more pertinent than ever.
