New paper in Language, Cognition and Neuroscience: Understanding the role of linguistic distributional knowledge in cognition

A paper on which I am joint-first author, which I previously posted here as a preprint, has just (after a long time!) been published in the journal Language, Cognition and Neuroscience.

Take a look!

It should be open-access, but if for some reason you can't see it properly there, I can give you a copy.

New paper in Cognitive Science: "Linguistic Distributional Knowledge and Sensorimotor Grounding both Contribute to Semantic Category Production"

A paper on which I am joint-first author, a preprint of which I mentioned here previously, has just been published in Cognitive Science.

Check it out!

If you don’t have access to Cognitive Science, you can get the paper from me.

New preprint: "Sensorimotor distance: A fully grounded measure of semantic similarity for 800 million concept pairs"

Together with my colleague and lab PILouise 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.

Two panels. Both show arrangement of dots labelled with concepts. Left panel: select nouns for tools, emotions, fruit and celestial objects. Right panel: select verbs for leg, hand, mouth and cognitive actions
Left panel: select nouns for tools, emotions, fruit and celestial objects. Right panel: select verbs for leg, hand, mouth and cognitive actions. Within each panel, positions are based on sensorimotor distances between concepts, transformed into two dimensions using Sammon mapping.

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.

Let us know if you do anything cool with it!

New preprint: "Linguistic Distributional Knowledge and Sensorimotor Grounding both Contribute to Semantic Category Production"

My colleagues Briony Banks, Louise Connell and I recently submitted a paper reporting research we've been doing at Lancaster University over the last year.

Needless to say, the Covid-19 lockdowns in the UK have been a substantial impediment to this work, so it's really good to see it finally complete.

A figure taken from the paper preprint. The computational model has two components, "linguistic" and "sensorimotor". The linguistic component is illustrated by colour spreading through a network of connected concepts ("animal", "husbandry", "horse", "cow", etc.). The sensorimotor component is illustrated with bubbles of colour growing and popping, creating new circles as they meet new points in the space ("animal", "cat", "rain", etc.). In the centre, the list of all concepts reached in either component are listed.
