Together with my colleague and lab PI, Louise Connell, I have developed a new measure of semantic distance between concepts. It is based on the senses and body parts involved in experiencing those concepts — in other words it is fully grounded in sensorimotor experience. This sets it aside from other measures of semantic distance, such as those based on distributions of words in language, on encyclopaedic databases, or on lists of properties or features. It also is fairly comprehensive (thanks to the expansive norms collected by colleagues), with distances available for nearly 800,000,000 pairs of concepts.
The measure is described in a new preprint, and you can search, visualise and play around with the distances (e.g. the above image) using an online app I also developed.
