Abstract
In order to improve the efficiency of deriving classification rules from a large training dataset, we develop in this paper a two-phase method for multi-attribute extraction. A feature that is useful in inferring the group identity of a data tuple is said to have a good inference power to that group identity. Given a large training set of data tuples, the first phase, referred to as feature extraction phase, is applied to a subset of the training database with the purpose of identifying useful features which have good inference powers to group identities. In the second phase, referred to as feature combination phase, these extracted features are evaluated together and multi-attribute predicates with strong inference powers are identified. A technique on using match index of attributes is devised to reduce the processing cost.
