Abstract: The invention describes a computer-aided method for automatically valuating the similarity of two character strings which are stored in a computer or to which the computer has access via an interface. First of all, associations which are present in the character strings are sought using a specification stored in the computer. The sought associations are then valuated using a first rule stored in the computer, with cohesive associations—subsequently also referred to as association strings—being given a higher valuation for the similarity of the character strings than non-cohesive associations. Finally, a second rule stored in the computer is used to derive a value, particularly a numerical value, from the valuation of the sought associations as a measure of the similarity of the two character strings.
