Our poster on #ontologymatching through absolute orientation of #embedding spaces has been accepted at @eswc_conf! Preprint here: arxiv.org/abs/2204.04040 Key take away: structurally similar graphs can be aligned by rotation of their corresponding latent embedding spaces.

I ran 1100km in #2021 🏃🏻‍♂️ This distance is roughly equivalent to walking from Mannheim to Rome in Italy 🇮🇹
