摘　　要：针对图书数量和种类较多,存在大量相似重复属性,设计了基于随机Petri网的图书相似重复属性记录存证系统。使用基于RFID读取器的数据输入装置,读取RFID标签上的信息。通过基于分布式文件系统的存证广场管理,查找所需要文件或证据,防止数据泄露。在用户接口装置中,利用随机Petri网来建模用户界面,方便用户存证。采用记录级别的相似度重复检测算法来衡量属性之间的相似度,根据相似度分值计算结果,标记时间戳,分析库所变迁的数据状态和变化,完成基于随机Petri网的记录存证方案设计。依据变迁行为规则,实现图书相似重复属性记录存证。由实验结果可知,该系统查准率、查全率的平衡点更接近1,存证时间在10 ms以内,可以有效完成图书相似重复属性记录存证。Aiming at the large number and types of books with a large number of similar and repetitive attributes,a book similar and repetitive attribute record and verification system based on stochastic Petri nets was designed.Use a RFID reader based data input device to read information on RFID tags.By managing the certificate storage plaza based on a distributed file system,search for the required files or evidence to prevent data leakage.In the user interface device,using stochastic Petri nets to model the user interface facilitates user authentication.A record level similarity duplicate detection algorithm is used to measure the similarity between attributes.Based on the similarity score calculation results,timestamps are marked,analyze the data states and changes that the library undergoes,and complete the design of a record preservation scheme based on a random Petri net.According to the rules of change behavior,achieve the record and certification of similar and repetitive attributes in books.From the experimental results,it can be seen that the balance point of precision and recall of the system is closer to 1,and the retention time is within 10 ms,which can effectively complete the retention of similar and repetitive book attribute records.
