A numerical estimate of the difference between two people, groups of people, or concepts. Often used in perceptual mapping. Similar to correlation, but varies only between 0 and 1. A similarity of 0 means the two units had completely different responses; a similarity of 1 means they are exactly the same.
The relationship between two objects that have exactly the same shape but not necessarily the same size.
gestalt principle of grouping, stating that people will tend to group similar items together.
a Gestalt perceptual principle stating that objects that look alike are more likely to be perceived as a group
a Getalt principle of organization holding that (other things being equal) parts of a stimulus field that are similar to each other tend to be perceived as belonging together as a unit
In geometry, objects or figures that are the same shape but not necessarily the same size.
Objects or figures that are the same shape are similar figures. They are not necessarily the same size. If two figures are similar, we say that there is similarity between the figures.
a term describing figures that are the same shape but are not necessarily the same size or in the same position.
The measure of the degree to which a document matches a query or the degree to which two or more documents are alike.
In perception, a principle by which we tend to group like figures, especially by color and orientation.
Having the same shape but not necessarily the same size.
In geometry, two shapes and are similar if there is a dilation (see the definition of dilation) that takes to a shape congruent to It follows that and are similar if they are congruent after one of them is expanded or shrunk.
Two shapes R and S are similar if there is a dilation D that takes S to a shape congruent to R. R and S are then similar if they are congruent after one of them is expanded or shrunk. This term is used in Geometry with objects that have the same shape, but not the same size. Also see the definition of "Dilation."
