Gollum: A Gold Standard for Large Scale Multi Source Knowledge Graph Matching

Understand

The number of Knowledge Graphs (KGs) generated with automatic and manual approaches is constantly growing.

• For an integrated view and usage, an alignment between these KGs is necessary on the schema as well as instance level.
• While there are approaches that try to tackle this multi source knowledge graph matching problem, large gold standards are missing to evaluate their effectiveness and scalability.
• We close this gap by presenting Gollum -- a gold standard for large-scale multi source knowledge graph matching with over 275,000 correspondences between 4,149 different KGs.
