Meet PyGraft: An Open-Sourced Python-Based AI Tool that Generates Highly Customized, Domain-Agnostic Schemas and Knowledge Graphs

Abstraction: PyGraft Python tool generates synthetic domain-agnostic knowledge graphs and schemas for benchmarking

Key points:

• PyGraft is the first generator designed to synthesize both a schema and the KG it supports in a unified pipeline with high user-specified configurability
• Addresses the problem that mainstream KG benchmark datasets share statistical properties (e.g., homophily), leading to overly optimistic evaluation of new models
• Domain-neutral output makes generated KGs suitable for benchmarking regardless of application area; critical for privacy-sensitive domains like healthcare and law
• Resources are constructed using extended RDFS and OWL elements; a DL reasoner ensures logical coherence and adherence to Semantic Web standards
• Research from Université de Lorraine and Université Côte d'Azur; code publicly released with documentation
• Stochastic-based generators can produce large graphs quickly but lack structural fidelity; schema-driven generators were previously limited to using pre-existing schemas
