Abstract: A method for cleaning data stored in a database which utilises a data fixing rule. The data fixing rule comprises a set of attribute values that capture an error in a plurality of semantically related attribute values. The data fixing rule also comprises a deterministic correction which is operable to replace one of the set of attribute values with a correct attribute value to correct the error. The method comprises applying the data fixing rule to the database to detect if the set of attribute values that captures the error is stored in the database and, if the set of attribute values is detected, the method applies the deterministic correction to correct the error in the attribute values.
