xsd:string Two or more distinct entities, which may be concrete or abstract objects or types, are characterized as being similar to each other. Depending on figure/ground relations, the entities may be expressed in two distinct frame elements and constituents , Entity_1 and Entity_2, or jointly as a single frame element and constituent, Entities. The similarity may be based on appearance, physical properties, or other characteristics of the two entities. However, no such Dimension has to be specified explicitly. The Entities may be like each other to a greater or lesser Degree. Rather than specifying the Dimension of difference, a Differentiating_fact may be mentioned. Notice that, although similarity presupposes the notion of a judge who assesses similarity, that judge is not part of the frame of similarity.
