Domain-specific Knowledge Graph Fusion (DKGF)

Gold definitionUpdated Apr 2, 2026

Definition

Domain-specific Knowledge Graph Fusion (DKGF) is a novel task designed to enrich specialized knowledge graphs (DKGs) by integrating relevant facts from broader general knowledge graphs (GKGs). It addresses key challenges such as high ambiguity in domain relevance and misalignment in knowledge granularity across graphs.

At a glance

Executive summary

Domain-specific Knowledge Graph Fusion (DKGF) is a method to make specialized knowledge graphs more complete by adding relevant information from larger, general knowledge graphs. It uses a smart system, like 'Fact-as-Program', to figure out what information is truly useful and how to fit it in correctly, even if it's described differently.

TL;DR

A way to make specialized knowledge databases more comprehensive by intelligently adding relevant facts from bigger, general databases.

Key points

Integrates facts from general knowledge graphs into domain-specific knowledge graphs.
Solves the problem of limited coverage in specialized knowledge graphs.
Used by researchers and engineers building domain-specific AI systems and knowledge bases.
Addresses challenges of domain relevance ambiguity and knowledge granularity misalignment, unlike simple merging.
A growing research area focused on automated knowledge acquisition and semantic integration for specialized AI.

Use cases

Enriching a medical knowledge graph with general biological pathways and drug interactions from a broader biomedical graph.
Augmenting a legal knowledge graph specific to contract law with general legal precedents and definitions from a comprehensive legal database.
Expanding a financial knowledge graph focused on a specific market sector with macroeconomic indicators and company relationships from a global financial knowledge graph.
Improving a scientific knowledge graph for materials science by integrating fundamental physics and chemistry principles from a general scientific knowledge base.
