| 摘 要： | 文本自动分类技术是信息处理领域的重要研究方向，在介绍文本分类应用以及其关键技术的同时，讨论了几种文本分类方法，并且在对这些分类方法分析的基础上，提出了一种规则和统计相结合的文本自动分类策略。该策略通过规则方法来放宽贝叶斯方法所要求的强独立性假设条件，同时当规则不能满足时，可以通过贝叶斯方法来得到更好的分类结果。

| Abstract: | In recent years, text categorization has become an important task in information processing. This paper introduces automatic text categorization, including its applications and its critical techniques. Furthermore ,it describes several classification methods which are frequently used ,and suggests a new classification method based on analysis of these methods.In this new method, rule is used to loose the strong independent condition required by Bayesian method,and Bayesian method is used to combine with rule method to get a better classification result. |
