Centre for Speech, Language, and the Brain (CSLB)

Department of Psychology

The Centre for Speech, Language and the Brain (CSLB) Concept Property Norms are a publicly-available resource for researchers, including those interested in semantic feature representations of conceptual knowledge. The resource currently provides semantic properties and associated production frequency data for 638 concrete concepts, with data for each concept collected from 30 participants.

For example, the properties of apple with production frequencies of two or more.

We also provide information on the considerable linguistic variation that underlies each normalized feature label (for apple, for example, "tastes good", "is tasty", "is delicious", and "is yummy" are all mapped to the normalized feature label is tasty).

We also provide similarity scores (cosines between concepts' feature vectors) for every pair of concepts in the norms.
