Dataset Usage

• The dataset is used to build a movie knowledge graph, supporting the NebulaGraph graph database.
• For detailed usage, refer to this link.

Dataset Schema Mapping

• The schema mapping details how the two tabular data sources are mapped to NebulaGraph's property‑graph model.

Dataset Validation

• After importing into NebulaGraph, execute SHOW STATS; to verify data integrity and ensure correct loading.
