| 摘 要： | 提出一种新的文档表示模型——基于共现词对的向量空间模型。模型以文档中共现的词对为基本考察对象，通过统计学特征选择有代表性的词对来表示文档。基于覆盖算法的文本分类实验表明此模型有较强的文档表示效果，为文本自动化处理提供了一条新思路。

| Abstract: | A new document representation model, a vector space model based on word co-occurrence（VSMBWC） is presen- ted in this article, which uses the co-occurring word pairs as the basic inspection object, and selects typical word pairs to represent document in statistical method. The text classification experiments based on cross cover algorithm show that this model is better in document representation, and provide a new way of thinking for text automatic processing. |
