Effective Table Data Extraction from PDF without LLM

Sparrow Parse helps to read tabular data from PDFs, relying on various libraries, such as Unstructured or PyMuPDF4LLM. This allows us to avoid data hallucination errors often produced by LLMs when processing complex data structures.

Hybrid RAG with Sparrow Parse

To process complex layout docs and improve data retrieval from invoices or bank statements, we are implementing Sparrow Parse. It works in combination with LLM for form data processing. Table data is converted either into HTML or Markdown formats and extracted directly by Sparrow Parse. I explain Hybrid RAG idea in this video.

Sparrow Parse - Data Processing for LLM

Data processing in LLM RAG is very important, it helps to improve data extraction results, especially for complex layout documents, with large tables. This is why I build open source Sparrow Parse library, it helps to balance between LLM and standard Python data extraction methods.

Invoice Data Preprocessing for LLM

Data preprocessing is important step for LLM pipeline. I show various approaches to preprocess invoice data, before feeding it to LLM. This is quite challenging step, especially to preprocess tables.

You Don't Need RAG to Extract Invoice Data

Documents like invoices or receipts can be processed by LLM directly, without RAG. I explain how you can do this locally with Ollama and Instructor. Thanks to Instructor, structured output from LLM can be validated with your own Pydantic class.

LLM JSON Output with Instructor RAG and WizardLM-2

With Instructor library you can implement simple RAG without Vector DB or dependencies to other LLM libraries. The key RAG components - good data pre-processing and cleaning, powerful local LLM (such as WizardLM-2, Nous Hermes 2 PRO or Llama3) and Ollama or MLX backend.
