Stanford University has just released a collection of large datasets of network data. When I say network data, I am referring to the mathematical term of networks (think of a collection of nodes and edges). Here are just a few of the possible categories.
- Citation Networks
- Road Networks
- Web graphs
- Social Networks such as twitter
- and many more
If you are looking to study network data, or just want some practice analyzing big data, this just might be a good place to start.
