Parsing PDFs (and more) in Elixir using Rust
I've been thinking a lot about how to accomplish various RAG things in Elixir (for LLM applications). PDF is one of the missing pieces, so glad to see work here. The really tricky part is not just parsing out the text (you can just call the pdftotext unix command line utility for that), but accurately pulling out things like complex tables, etc in a way that could be chunked/post processed in a useful way. I'd love to see something like Unstructured or Marker but in Rust that Elixir could NIF out to it.

Let Claude read your Gas Meter with this Amazing new Feature
There are many tools that can help you understand images in PDF, including tables, etc. with powerful tools such as unstructured. But supporting this capability in ChagGPT and Cluade for everyday use cases (but also via API) takes it to a whole new level.

LLMs for Report Validation
Depends on how fuzzy your definition of template is. If it's really structured, a simpler algorithm might work better. Otherwise maybe try https://github.com/Unstructured-IO/unstructured

Bash One-Liners for LLMs
I’ve been looking at this
https://freeling-user-manual.readthedocs.io/en/v4.2/modules/...
at the freeling library in general, also spaCy and NLTK. The chunking algorithms being used in the likes of LangChain are remarkably bad surprisingly.
There is also
https://github.com/Unstructured-IO/unstructured
But I don’t like it, can’t explain why yet.
My intuition is that 1st step is clean sentences and paragraphs and titles/labels/headers. Then probably an LLM can handle outlining and table of contents generation using a stripped down list of objects in the text.
BRIO/BERT summarization could also have a role of some type.
Those are my ideas so far.
