This paper designs the automatic text categorization system of public security information based on Support Vector Machine,according to the requirements of public security information.This system not only distinguishes the text classification automatically,but also retrains the features information at different stages of the categorization process.It will support the further information procession.Meanwhile,this system reduces the coupling degree of the subcomponents,provides the flexible system structure,and improves the adaptability of system.

根据公安情报分类系统的需求,设计了基于支持向量机的公安情报分类系统,该系统不仅能够实现情报文本的自动分类,而且能够保留在情报文本分类的不同阶段语料的特征信息,为情报信息的进一步加工处理提供支持,同时系统中各模块间采用松耦合的方式衔接,提高了系统的适应性和灵活性。

A cataloged classification of books consists of general works and specific works, and the traditional practice of classifying books into specific classes and special classes should be given up. Edition study classifies editions into written editions, which are reclassified into hand-written, copied, and photo-offset manuscripts, and printed editions, which are re-divided into carved, typed, lithographic and block-printed editions. All these will be re-reclassified according to time region, subject and craftsmanship.

摘 要:&文献&内涵有古今之分,不宜模糊;文献学的研究对象是&文献的文本&而不是我们通常所说的&文献&;&分类&与&编目&是目录学两大基本内容,不宜混而不清;目录学中的书目分类应分为综合性书目、专门性书目两大类,不宜再继续所谓专科目录、特种目录等旧的分类方法;版本学中的版本分类宜分为写本与印本两大类,其下写本再分为稿本、抄本、影写本,印本再分为刻本、活字本、石印本,刻本之下再根据时间、地区、主体、工艺等划分类别,这样方可层次清楚、泾渭分明。

In the traditional AdaBoost method,the weights are updated based on the weak classifier's overall error rate, this article proposes one kind of the method which unifies the level of difference between the threshold and the feature value of the weak classifier with the weak classifier's overall error rate. Compared to the method which only based on the overall classification error rate to update the weights,this method can achieve higher detection rate while reduces the mistaken-detection rate.

在传统AdaBoost方法中,权重是根据弱分类器的整体错误率来更新的,本文提出了一种将弱分类器的阈值与特征值相差程度和弱分类器的整体错误率相结合来更新样本权重的方法,相比较只根据整体分类错误率来进行权重更新的方法,这种方法可以在降低误检率的同时达到较高的检测率。
