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。

At first This paper formulates the necessity for depurating network information content,and introduces the history of information security and study point in information security.Also this paper analyses in detail the key technology of content filtering such as data frame capture,bridge, network protocol analysis and content analysis.And then this paper comes up with the solution for content filtering facing application layer which is based on the technology of protocol analysis and format conversion in combination with text filtering techonology of Multiple Patterns Matching..Also this paper amplifies on the design and the implement method of each module.Finally this paper introduces how the client of content filtering system manages the keywords and log and makes suggestion for the improvement of the system.

本文首先阐述了对网络信息内容净化的必要性，介绍了信息安全的发展过程以及当前信息安全方面的研究重点，详细分析了内容过滤的关键技术，如数据帧捕获、网桥、网络协议分析和内容分析等方面的技术，然后提出了在Windows2000下实现基于协议分析技术，结合多模式匹配的文本过滤技术，面向应用层的内容过滤解决方案，并给出了内容过滤引擎的详细设计以及各个模块的实现方法，最后介绍了内容过滤系统客户端对有害信息关键词和日志的管理以及对本系统改进的一些建议。

Three main shortcuts are listed out: the first is the data can t be collected easily which holdbacks the statistics and analyses; the second is the system s extension and adaptability are poor and the data structure and code are redundant; the third is the communication of the same kind management information system is weak and the communication risks on some danger.

本文着重从解决这三个方面的问题入手，提出了&柔性&管理信息系统的模型，着重讲述了系统设计的方法和理论，并给出了&柔性&管理信息系统的定义，以及系统的基于组件的设计范式，体现了使用者既是开发者的主题思想，利用面向对象的循环迭代式软件设计方法，通过对模块间的耦合度和模块内聚合度的分析，来验证系统的科学与先进型。

Entire system interposes from system administration , the information doing business basically , the information administration doing business , the information doing business analyse , stock information manages five modules made up of.

整个系统由系统管理、基本营业信息设置、营业信息管理、营业信息分析、库存信息管理五个模块组成。

In research of software engineering domain, we thought that one of the thorniest problems about component implementation was the abstract and extraction of domain components.

故本文在领域工程技术基础上，从特定领域建模的角度出发强调了领域构件的提取与抽象，并以机械加工工艺信息管理领域为例，分析该信息管理系统的领域特点后，进行了机械加工工艺信息管理构件的提取和抽象，并结合计算机软件总线的体系结构提出了基于机械加工工艺信息管理系统的应用软件集成框架。

The system completes the entire process management of human affairs, checking attendance, the wages, training, user, etc. on the basis of conforming to operation easily, contact surface friendly, nimble, practical and safe. It is including establishment of the new staff 's personnel record, the senior staff exited, the staff's information revision causing by changing position and so on, the staff's information inquiry , the attendance management, and the staff's wages management , such as wage inquiry, revision, paying, wage information printed. It also contains staff training information management and the user's account number password management.
