Dynamic Network Datasets

This repository contains a structured collection of dynamic (temporal) network datasets focused on human networks, with consistent formatting, standardized naming, and a hierarchical folder structure to support reproducibility and reuse. Each dataset records the interactions or connections between entities (nodes) over time.

The data is formatted as plain text files, where each line represents a temporal edge in the form:

nodeA  nodeB  timestamp

Datasets include:

• 50 Human-based Networks: Interactions between people or human-generated data.

Each type is further organized into logical categories based on network characteristics to facilitate research and analysis.

Dataset Overview

Human Networks

This collection of 50 human dynamic networks were acquired and structured from well-established public data repositories, including SNAP, Network Repository, SocioPatterns, WoSNet, and datasets collected by Opsahl et al.
