Sparrow Parse API for PDF Invoice Data Extraction

I explain how Sparrow Parse API is integrated into Sparrow for data extraction from PDF documents, such as invoices, receipts, etc. 

 

Avoid LLM Hallucinations: Use Sparrow Parse for Tabular PDF Data, Instructor LLM for Forms

LLMs tend to hallucinate and produce incorrect results for table data extraction. For this reason in Sparrow we are using Instructor structured output for LLM to query form data and Sparrow Parse to process tabular data within the same document in combined approach. 

 

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. 

 

Instructor and Ollama for Invoice Data Extraction in Sparrow [LLM, JSON]

Structured output from invoice document, running local LLM. This works well with Instructor and Ollama.

 

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.
