Numerical data on ogbl_wikidata2

[aahad5555]

Hi, I am quite new to knowledge graphs and came across ogbl_wikidata2 dataset. I cant get my head around that this dataset is just numbers. I have a simple question why is that?and is their any real entity or data behind that?

Hi @aahad5555, I guess you mean ogbl-wikikg2. If you download the data by using the OGB dataloader, you will find the mapping file under the folder dataset/ogbl_wikikgv2/mapping, which map numbers to wikidata entity/relation IDs.

In a IPython shell, running the following scripts should show you the folder

from ogb.linkproppred import LinkPropPredDataset

dataset = LinkPropPredDataset(name = 'ogbl-wikikg2')

!ls ./dataset/ogbl_wikikg2/mapping
