In this paper, vector-distance-weighted algorithm and representative-vector-distance algorithm are described and used to implement the process of automatic text classification. Two experiments have been done by means of the algorithms (experiment1 is based on vector-distance-weighted algorithm and experiment2 is based on representative-vector-distance algorithm). Characters are selected as features. The average precision of experiment1 and experiment2 is 80.36% and 69.27%, respectively. Comparing the two experiments, it can be concluded that the efficiency of text classifi...
