gammagl.datasets.IMDB

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

A subset of the Internet Movie Database (IMDB), as collected in the “MAGNN: Metapath Aggregated Graph Neural Network for Heterogeneous Graph Embedding” paper. IMDB is a heterogeneous graph containing three types of entities - movies (4,278 nodes), actors (5,257 nodes), and directors (2,081 nodes). The movies are divided into three classes (action, comedy, drama) according to their genre. Movie features correspond to elements of a bag-of-words representation of its plot keywords.

Parameters:

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

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

  • (bool (force_reload) – (default: False)

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