摘　　要：针对现有智能电子图书信息分类系统,存在分类功能和应用性能差的问题,利用朴素贝叶斯相关概念,从硬件和软件两个方面实现智能电子图书信息自动分类系统的优化设计。在硬件方面,改装信息采编设备,加设朴素贝叶斯分类器,扩大系统存储器的存储空间,在供电电路中设置电源隔离电路,以保证系统的运行安全。在硬件设备的支持下,通过中文分词、文本标记的删除等步骤,处理初始电子图书信息数据,提取图书的词频特征。利用朴素贝叶斯确定电子图书的类型,实现系统的图书信息自动分类功能。通过系统测试实验得出结论:与现有分类系统相比,设计系统的查准率、查全率和F测试值分别提高了9.65%、10.58%和10.10,应用设计分类系统后智能电子图书的查询耗时更短,即设计系统在分类功能和应用性能两个方面更加具有优势。In view of the poor classification function and application performance of the existing intelligent e-book information classification system,the optimal design of intelligent e-book information automatic classification system is realized from two aspects of hardware and software by using the related concepts of naive Bayes.In terms of hardware,refit the information acquisition and editing equipment,add a naive Bayesian classifier,expand the storage space of the system memory,and set a power isolation circuit in the power supply circuit to ensure the operation safety of the system.With the support of hardware equipment,the initial e-book information data is processed and the word frequency characteristics of books are extracted through Chinese word segmentation,text mark deletion and other steps.Using naive Bayes to determine the type of e-books,the automatic classification function of book information is realized.Through the system test experiment,it is concluded that compared with the existing classification system,the precision,recall and F test value of the design system are improved by 9.65%,10.58%and 10.10%respectively.After the application of the design classification system,the query time of intelligent e-books is shorter,that is,the design system has more advantages in classification function and application performance.
