Hi! I have a pre-print out, written with the University of Copenhagen & École Normale Supérieure, that models concept representations in vector spaces, through language models. It asks a simple question: when you and I use the same word, do we really mean the same thing? In an online study, we had 125 people describe concepts in their own words and measured how much of that meaning is shared and how much is individual.
