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.
