Abstract
In a method of identifying unusual combinations of values in data (1) that is arranged in rows and columns, the data is pre-processed to put it into a form (4, 5) suitable for application of a search method thereto. Using said search method, the pre-processed data is searched (8) to search the set of possible combinations of unique values from the columns to find any combinations that are unusual according to an evaluation metric.
