You Ask, I Answer: Chunking Enterprise Data for AI Analysis?

In today's episode, Tom asks how do you deal with the context window limitations when asking AI to analyze massive multi-year business reports? Even with the one million plus token context windows, the AI sometimes forgets the middle of the document or hallucinates connections that aren't there. What is the strategy for breaking down enterprise data so the AI actually comprehends the whole picture? How do you do it as a human? And it's not facetious.

How do you do it as a human? As a human, you probably chunk things, you probably break them down into pieces. So the first thing you have to do is forego the idea that AI can hold all that information into its knowledge. It can't put it in a database, put in an AI aware database. And it can really honestly be any database PostgreSQL, MySQL, MariaDB, Microsoft SQL Server, doesn't matter.

Second, ideally the database you're working with has some kind of um vectorization. So PostgreSQL, for example, has PG vector, BigQuery has its own vectorization. Because what you're going to want to do here is you're going to want to provide some kind of knowledge graph, some kind of ontology onto the data so that AI has essentially a map of what lives where. I use a tool called Graphify, it's free, but there's Neo4j. There's so many different knowledge graph tools that have been invented over the years that will solve this exact problem.

What you want what we're trying to do is we're trying to take massive amounts of data and distill them into an index, like a card catalog of the library, so that AI can go look things up as it pieces things together. Second, in the prompting process itself and in your agentic workflow, you want to have it so that the AI tool is taking notes along the way of key points and storing that in its own database so that it's essentially taking a very large document, distilling the key points down to a smaller document, and then it can sew those together. So we're kind of you know uh uh chunking. In my book Almost Timeless, the 48 Principles uh Foundation Principles of Generative AI, uh, which you can buy over at cs pen.gumroad.com, one of the big things that I talk about is uh plan big, act small. And this applies not only to the use of models but how we how we structure data.

We do what's called what's called scaffolding, where you do a big pass or a big strategy first, and then you start taking the data and chunking it up into little tiny pieces and processing each piece, storing the results, and then processing the results, sort of laddering up to that final big analysis. Along the way, there are checkpoints and evaluations that are part of the process so that uh it is it is reducing the likelihood of hallucination by by checking its own work along the way. And those evaluations can be, you know, is this is this analysis that I just did corroborated by the data? Right? Does the data actually say that?

The tools can do that, they can they can access the data that you give them and say, yes, this is the this is representative of the data that I was given, or no, I made this up, and perhaps we need to revisit, you know, revisit or reassess. They can do that with data systems. So fundamentally, if you're trying to do large-scale data analysis in a transformers-based AI model itself, it's not going to go well. If, on the other hand, you're having it work with real databases and things like Python code to do deterministic analysis, that is going to work much better for you. You're gonna have a much better time if you have AI do its data analysis that way rather than trying to do it in a transformer.

AI models themselves really should be reserved for doing language based stuff. So once you've got the data from your your Python data analysis scripts, then hand that off to AI to summarize to um to wrap up the analysis and stuff. That's how I would do that to avoid those hallucinations. If you're doing large scale data analysis, you can even do um classical AI on unstructured data. There's a whole field called natural language processing where you are you are having it do like keyword extraction through older algorithms like TFIDF or using language models at scale one document at a time to digest stuff down.

That's that's how I would do that because that will get you really good results that are hallucination free because they're deterministic, it's deterministic code, and then the analysis, the outputs go into your language model for summary. It's a lot of work, it will take a lot of time, but you will get much better results that way. Thanks for the question, talk to you on the next one.
