Natural language processing for extracting conveyance graphs

This invention describes a computer system that takes old, unstructured property records, often scanned documents from county offices, and pulls out key information about property transfers. It works by first identifying the location (jurisdiction) of each document, then applying a suitable language processing program. The core of the invention, as described in the claims, relies on using specific, hand-coded rules to extract details and then storing them in a standardized computer format like JSON or XML.

Why it matters: Filed before the widespread adoption of powerful Large Language Models (LLMs), the hand-coded pattern-matching rules described in the claims could now be largely replaced or significantly augmented by LLMs, making the extraction process more robust and scalable across diverse document types and jurisdictions.
