# Political Blogs (Polblogs)

**Task**: Political-leaning classification  
**Size band**: small · **Label type**: semantic  
**Label column**: `leaning` · **Converter**: `converters/convert_small_text.py`

Hyperlink network of US political blogs captured before the 2004 election. Label is the blog's political leaning (0 = liberal, 1 = conservative). Community structure correlates strongly with the label.

## Converted graphs (neext/)

| graph | nodes | edges | classes | feature cols | isolated | class counts |
|---|---|---|---|---|---|---|
| default | 1,490 | 16,715 | 2 | 0 | 266 | 0: 758, 1: 732 |

*Conversion notes*: Netzschleuder CSV bundle; 'value' column (0=liberal, 1=conservative) used as label; blog names dropped; directed hyperlinks symmetrized. Contains isolated nodes.

## Caveats

- ~266 isolated nodes; NEExT's filter_largest_component or explicit nodes.csv handling decides their fate.
- Newman's UMich mirror blocks scripted access; Netzschleuder is the reliable source.
