Abstract: An algorithm SLIQ which uses Gini index to select attribute is presented. How to improve efficiency is also discussed . A feasible method based on SLIQ is applied to the generation unit's bidding decision system of electricity market. The knowledge that the ability of unit bidding is gained by data mining , this knowledge is very useful to supporting the bidder to make decisions.
