1. A computer-implemented process for establishing a measure of an image-based semantic distance between semantic concepts, comprising: using a computer to perform the following process actions: respectively computing a semantic concept representation for each concept based on images associated with the concept; and computing a degree of difference between two semantic concept representations to produce said image-based semantic distance measure for the pair of corresponding semantic concepts.
