Creating a multi-relational ontology having a predetermined structure

This invention describes a computer system for building a structured knowledge base, called an ontology. It works by defining a fixed set of concept types and relationship types, then creating facts by linking two concepts with a relationship. The system can also track where each piece of information came from, including specific documents or data sources.

Why it matters: Filed before advanced AI could automatically extract concepts and relationships from text. Large Language Models now make populating such a structured knowledge base from documents, as described in the claims, significantly more efficient and scalable.
