Thank you for putting a smile on my face

Love the way you're tackling some of the bigger issues facing RAG use instead of just repeating material that is out there on KZfaq already. I've been able to follow along and extend your examples for my needs readily. Do you have a timeframe as to when you'll make some small updates to util.py that will allow it to process control characters better that are oftentimes embedded in PDF documents? I've made private changes for now and will propagate as necessary, however.

Apologies for being slightly lazy and not testing this out myself yet - but what happens if you attempt to parse a scanned image PDF, are there checks in place to detect whether text is present and warn if none is found? Also, suppose I first OCR my scanned image PDF's and then embed the text layer into the PDF (using something OCRmypdf or MSOCR), would this approach work in that situation?

Thank you for your excellent question! We are going to be adding something to LLMWare to address this issue and may post a video on this later in the month so please stay tuned!

This is a joy indeed! Apologies for the very basic question, but does all of this run locally? Is an LLM used to detect the tables? If not, what other technology is being used?

@llmware 4 ай бұрын

Hi we have a number of models, most of which can run locally quantized or are even 1B. For the detection of tables, however, we use our parsers which we have built ourselves to detect tables so does not rely on LLMs to detect.

what if I don't want to use a Library (database) but just a folder to upload the pdfs and save the tables? I can't find how to do it cause the parsing function does not saves any tables

does this pdfs has to be editable or it can be images too?

@llmware 9 ай бұрын

The PDF has to be editable (able to be digitally parsed) because otherwise we can only scan it with OCR.

This is great stuff, guys! There's so much regurgitated material out there that refuse to deal with some of the approaches to RAG and you're tackling it head-on for the community! Hopefully one of your upcoming updates will modify the util.py to add encoding='utf-8' to the file opening line + add some logic like the following to take care of embedded control characters in the PDFs try: c.writerow(cfile[z]) except UnicodeEncodeError as e: # Get the problematic character from the error message unicode_char = str(e).split("'")[1] cleaned_row = [str(field).replace(unicode_char, '') for field in cfile[z]] c.writerow(cleaned_row)
