Synthetic Data For Graph Analytics

Definition and Core Concepts

Synthetic data refers to artificially generated data that mimics the statistical properties and structure of real-world datasets. In the context of graph analytics, synthetic data is designed to replicate the nodes, edges, and relationships found in real-world graphs. These graphs can represent anything from social networks to transportation systems, making synthetic data a versatile tool for testing, modeling, and analyzing complex systems.

Key concepts include:

• Graph Structure: Synthetic data preserves the topology of graphs, including nodes (entities) and edges (relationships).
• Scalability: Synthetic datasets can be generated at any scale, enabling analysis of large and complex graphs.
• Privacy Preservation: Synthetic data eliminates sensitive information, ensuring compliance with data privacy regulations.
• Customizability: Parameters can be adjusted to simulate specific scenarios or behaviors within a graph.
