Nowadays most of text categorization algorithms use vector space model. It can not make full use of position of terms, and the position brings much semantic information. This paper proposes a coordinate model. By using this model, the terms’ position information can be utilized. In this model, some central terms are selected as origin and a multidimensional space is built, other words will be put into this space by their position relative to these origin. In our experiment, we present a boost algorithm based on coordinate model. The result shows that there are much information can be mined from coordinate model.
