Abstract
A method according to the present invention enables the similarity between sequences of symbols to be determined using rules generated from a dictionary-based compression scheme according to the content of the columns from databases. Pairs of symbols can replaced by rules that do not comprise a repeated combination of two symbols and where each rule occurs more than once in the sequence of symbols. The similarity of each set of rules can then be expressed numerically.
