Community Search: A Meta-Learning Approach

Understand

Community Search (CS) is one of the fundamental graph analysis tasks, which is a building block of various real applications.

• Given any query nodes, CS aims to find cohesive subgraphs that query nodes belong to.
• Recently, a large number of CS algorithms are designed.
• These algorithms adopt predefined subgraph patterns to model the communities, which cannot find ground-truth communities that do not have such pre-defined patterns in real-world graphs.
