Modelling Asymmetric Similarity with Prominence

Research output: Working paper


This paper aims to introduce and discuss a geometrically based model, the relative prominence model, which is inspired by Tversky's (1977) finding that a factor behind asymmetric similarity seems to be the "relative prominence". The model proposes that the experienced directed similarity from I to J is proportional to some symmetric similarity measure between I and J, and the quotient between the "prominences" for J and I. Analysis of empirical data from different areas shows that it is possible for a procedure to estimate the parameters of the model quite well. The paper is concluded with a discussion of the differences between the relative prominence model and related models that handle asymmetry in terms of "stimulus bias".
