      The Italian Space Agency’s Light Italian CubeSat for Imaging of Asteroids,
      or LICIACube, will fly by Dimorphos to capture images and video of the
      impact plume as it sprays up off the asteroid and maybe even spy the
      crater it could leave behind.

KnowGL: Knowledge Generation and Linking from Text

The knowgl-large model is trained by combining Wikidata with an extended version of the training data REBEL dataset. Given a sentence, it generates triple(s) in the following format -

[(subject mentions # subject label # subject type) | relation label | (object mentions # object label # object type)]

If there are more than one triples generated, they are separated by $ in the output.

The model achieves state-of-the-art results for relation extraction on the test dataset of REBEL. See results in Mihindukulasooriya et al (ISWC 2022).

The generated labels (for subject, relation and object) and types (subject and object) can be directly mapped to Wikidata IDs associated with them.
