MMKG: Multi-modal Knowledge Graphs

We present Mmkg, a collection of three knowledge graphs that contain both numerical features and (links to) images for all entities as well as entity alignments between pairs of KGs. Therefore, multi-relational link prediction and entity matching communities can benefit from this resource. We believe this data set has the potential to facilitate the development of novel multi-modal learning approaches for knowledge graphs. We validate the utility of Mmkg in the \(\mathtt {sameAs}\) link prediction task with an extensive set of experiments. These experiments show that the task at hand benefits from learning of multiple feature types.
