Abstract: A primitive automatic answering system model's algorithm and working mechanism are provided. Based on the analysis of the model, a new intelligent answering model based on knowledge tree-based data generalization and association rule mining of pattern are come up with. In the end, the improvement of this model in intelligence is analyzed and proved through an experiment.
