Similarity and dissimilarity measures are widely used in many research areas and applications. When a dissimilarity measure is used, it is normally required to be a distance metric. However, when a similarity measure is used, there is no formal requirement. In this talk, we first give a formal definition of similarity metric. We then show the relationship between similarity metric and distance metric. Finally, we present general solutions to normalize a given similarity metric or distance metric.
