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

Bases: InMemoryDataset

来自“政治博客圈与2004年美国大选：分裂的博客”论文的政治博客数据集。

Polblogs 是一个包含1,490个顶点（代表政治博客）和19,025条边（博客之间的链接）的图。 这些链接是从博客首页的爬取中自动提取的。 每个顶点都有一个标签，表示博客的政治倾向：自由派或保守派。

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)
