NEExT Egonet Experiment Datasets

Single-graph network datasets with per-node class labels, curated for egonet-based node classification with NEExT: each node's k-hop egonet becomes a subgraph, subgraphs are embedded, and nodes are classified by their egonet embeddings.

Every dataset folder contains:

• card.md — information card: task, stats, source, license, citation, caveats
• metadata.json — machine-readable: source URLs, sha256 checksums, per-graph stats, conversion details
• neext/ — NEExT-ready tables per graph: edges.csv/nodes.csv and Parquet mirrors (edges.parquet/nodes.parquet; for coauthor-cs, coauthor-physics and reddit-graphsage the Parquet nodes include full feature matrices omitted from CSV for size)
• source/ — original upstream files, unmodified, hash-recorded

Table contract: edges (src_node_id,dest_node_id) + nodes (node_id, <label>, features...), int64 node IDs, undirected deduplicated edges, fully-populated label column.

Licensing: each dataset keeps its upstream license/terms — see the per-dataset card.md. This repository is a research mirror; cite the original authors listed in each card.
