Load the FB15k-237 dataset

FB15k-237 is a reduced version of FB15K. It was first proposed by [TCP+15].

The FB15k-237 dataset is loaded from file if it exists at the AMPLIGRAPH_DATA_HOME location. If AMPLIGRAPH_DATA_HOME is not set the the default ~/ampligraph_datasets is checked.

If the dataset is not found at either location it is downloaded and placed in AMPLIGRAPH_DATA_HOME or ~/ampligraph_datasets.

The dataset is divided in three splits:

  • train
  • valid
  • test
