Abstract
A method of computing a similarity between a first transaction having a set of properties and a second transaction having the set of properties includes computing an initial weight for each of the properties of the set of properties and computing a similarity between each of the properties of the first transaction and the properties of the second transaction. The method also includes adjusting the initial weight for each of the properties based on a measure of the commonness of each of the properties of the set of properties, normalizing the adjusted weights, and computing the similarity by summing the products of the normalized adjusted weights and the computed similarities.
