Knowledge Graph Generation Method for AI Systems
Summary
Fujitsu Limited has filed a patent application (US20260094018A1) with the USPTO for a knowledge graph generation method enabling AI systems to process multiple input documents through cause-result relationships. The application was published on April 2, 2026, with inventors including Tatsuru Matsuo.
What changed
The patent describes a three-stage knowledge graph generation method for AI systems. The first stage selects a primary entity from an initial knowledge graph containing events connected by cause-result relations based on a first input document. The second stage generates a second knowledge graph including entities representing events from a second input document related to the selected first entity. The third stage connects the first and second knowledge graphs through cause-result relations to form an integrated third knowledge graph.
This patent application does not impose compliance obligations on any regulated entity. Technology companies and AI developers may review the CPC classification G06N 5/022 for landscape awareness and assess potential licensing implications if developing similar knowledge graph technologies.

Abstract
A generation method includes, selecting a first entity from a first knowledge graph that includes a plurality of the first entities indicating events connected by a cause-result relation based on a first input document, generating a second knowledge graph that includes a second entity indicating each of events connected by a cause-result relation included in a second input document, that is related to the first entity, based on the selected first entity and the second input document, and generating a third knowledge graph by connecting the first knowledge graph and the second knowledge graph by processor.
