torch_geometric.datasets.PolBlogs

class PolBlogs(root: str, transform: Optional[Callable] = None, pre_transform: Optional[Callable] = None, force_reload: bool = False)[source]

Bases: InMemoryDataset

The Political Blogs dataset from the “The Political Blogosphere and the 2004 US Election: Divided they Blog” paper.

Polblogs is a graph with 1,490 vertices (representing political blogs) and 19,025 edges (links between blogs). The links are automatically extracted from a crawl of the front page of the blog. Each vertex receives a label indicating the political leaning of the blog: liberal or conservative.

Parameters:

  • root (str) – Root directory where the dataset should be saved.

  • transform (callable, optional) – A function/transform that takes in an torch_geometric.data.Data object and returns a transformed version. The data object will be transformed before every access. (default: None)

  • pre_transform (callable, optional) – A function/transform that takes in an torch_geometric.data.Data object and returns a transformed version. The data object will be transformed before being saved to disk. (default: None)

  • force_reload (bool, optional) – Whether to re-process the dataset. (default: False)
