Network Data Repository. An Interactive Scientific Graph Data Repository.

a scientific network data repository with interactive visual analytic tools.

The first interactive data and network data repository with real-time analytics. Network data repository is not only the first interactive repository, but also the largest network repository with thousands of donations. This large comprehensive collection of network graph data is useful for making significant research findings as well as benchmark data sets for a wide variety of applications and domains (e.g., network science (complex network data), bioinformatics, machine learning, data mining, physics, and social science) and includes relational, attributed, heterogeneous, streaming (temporal network data), spatial (spatial network data), and time series data as well as non-relational machine learning data. All data sets are easily downloaded into a standard consistent format. We also have built a multi-level interactive graph analytics engine that allows users to visualize the structure of the networks as well as macro-level graph statistics as well as important micro-level properties of the nodes and edges.




About

Our vision

Scientific progress depends on standard datasets for which claims, hypotheses, and algorithms can be compared and evaluated. Despite the importance of having standard datasets, it is often impossible to find the original data used in published experiments, and at best it is difficult and time consuming. This site is an effort to improve and facilitate the scientific study of complex networks by making it easier for researchers to download, analyze, and investigate a large collection of network data. Our goal is to make these scientific network datasets widely available to everyone while also providing a first attempt at interactive analytics on the web.

We are always looking for talented individuals to help us with this project, so please contact us if you'd like to contribute to this project.

Download network data!

Thousands of benchmark network data sets

Download hundreds of benchmark network data sets from a variety of network types (social network data, brain networks, temporal networks, etc.). Also share and contribute by uploading recent network data sets. Naturally all conceivable data may be represented as a graph for analysis. This includes recommendation system data (user purchases products, or user trusts another user), social networks, web graph data, and numerous other real-world datasets.

Network data may be visualized interactively via our web-based network analysis tool.
