Therefore to make an intensive research on rough set theory will be of great benefit to extract valuable and easily understood knowledge from large amounts of data more effectively . it will also be of great benefit to popularize and apply data mining to commercial systems 对粗糙集理论作深入的研究,将有利于更加有效地从海量数据中提取出有价值且可理解性强的知识,也有利于数据挖掘在商业中的进一步普及和应用。
Unreliability results from the invalid corporate governance , from the cpa lacking audit independence and from the low cost of counterfeiting accounting information . shortness of understandability derives form the over - professionalization in id and from the investors " poor ability to use it 而信息缺乏可理解性,一方面是因为部分会计信息过于专业化,另一方面是由于投资者,尤其是个人投资者获得信息和理解信息的能力很差。
7 ) several examples are employed to demonstrate the validity of dissertation approach . in order to enhance the intelligibility of the mining process and result , this dissertation uses the visualization technique to deal with the predictive model and the model of decision rule 7 )多个实例的验证结果证明了论文方法的有效性,除此之外,论文又通过可视化技术对预测模型、决策规则模型进行处理,增强了挖掘过程与结果的可理解性。
It is very important to ensure the reliability , comparability , relevance , understandability and timeliness of accounting information so as to bring into play its social functions . on the other hand , the accounting information rules which the accountants produced and supplied must be exotic , applicable and consistent in order to assure its quality . accounting system is just the intermedium which supplied the common accounting information systematically , roundly , concretely , understandably and operationally 保证会计信息的可靠性、可比性、相关性、可理解性和及时性,对于发挥会计信息的社会功能至关重要;另一方面,为了保证会计信息质量,会计人员生产和提供会计信息的规则必须是公开、适用、一致的,而系统、全面、具体、易理解、易操作地提供这些共同会计信息的媒介,就是会计制度。
Although both preparing and auditing financial statements need to apply the concepts of materiality , the purposes of implementing the principle of materiality in financial accounting system differs from the purposes of applying the concepts of materiality in auditing procedures . because , the former distinguishes immaterial items in accounting data for reducing the producing cost of information as well as enhancing the understandability of financial statements , but the latter put much more attention on scrutinizing information for significant items in order to control audit risks and conduct an efficient and effective audit engagement 财务会计中财务报表的编制,以及审计中财务报表的查核,都需要运用重要性概念;但财务会计中重要性原则的运用,主要是用于过滤筛选不重要的会计数据,以节约信息生产成本,并增强报表的可理解性;而审计中重要性原则的运用,则是为了辨识重大会计信息,以控制审计风险,并有效率且有效果地完成审计任务。
The table will write down all about the electronic records during their life period . the content noted in the table will be the only basis on original and reality " testing of electronic records " . the major task of the second levels is to build the tight filing rules , moreover , combined the " life cycle table " , to build the test system to assure the original and the reality of the information during filing ; the assignment of the third level is to build testing and restoring measures of the original and the reality . by maintaining the media of electronic archives or building information file of electronic archives etc , electronic archives can maintain their available ^ visuak understandable during their deadline ; meanwhile , to build the safe control of the system through the workers dispersed authorization and deterring skills , to formulate the standards of the protective system , such as the standard of the basic structure of united electronic records ^ electronic archives . all of this is important to protect the original and the reality of electronic records and electronic archives “生命周期表”所记录的内容将作为电子文件归档时检验原始性、真实性的唯一依据;电子文件归档管理层中的主要任务是要建立起严密的归档制度,同时结合“文件生命同期表”建立检验措施保证电子文件在归档过程中信息内容的原始性、真实性;电子档案保管层中主要任务是建立电子档案数据原始性、真实性检验及原始数据恢复管理措施,通过对电子档案载体的维护、建立电子档案维护管理的信息文档等工作,确保在保管期限中的电子档案保持其可用性、可存取性、可理解性:建立电子文件与电子档案原始性、真实性保护体系安全控制,通过对系统工作人员授权分散化、建立用户标识与认证技术等措施确保“保护体系”安全运行;加强“保护体系”涉及的标准与规范的制定工作,如建立统一的归档电于文件、电子档案基本结构等标准对保护电子文件、电子档案信息原始性、真实性有着重要意义。
Network forensics is an important extension to present security infrastructure , and is becoming the research focus of forensic investigators and network security researchers . however many challenges still exist in conducting network forensics : the sheer amount of data generated by the network ; the comprehensibility of evidences extracted from collected data ; the efficiency of evidence analysis methods , etc . against above challenges , by taking the advantage of both the great learning capability and the comprehensibility of the analyzed results of decision tree technology and fuzzy logic , the researcher develops a fuzzy decision tree based network forensics system to aid an investigator in analyzing computer crime in network environments and automatically extract digital evidence . at the end of the paper , the experimental comparison results between our proposed method and other popular methods are presented . experimental results show that the system can classify most kinds of events ( 91 . 16 ? correct classification rate on average ) , provide analyzed and comprehensible information for a forensic expert and automate or semi - automate the process of forensic analysis 网络取证是对现有网络安全体系的必要扩展,已日益成为研究的重点.但目前在进行网络取证时仍存在很多挑战:如网络产生的海量数据;从已收集数据中提取的证据的可理解性;证据分析方法的有效性等.针对上述问题,利用模糊决策树技术强大的学习能力及其分析结果的易理解性,开发了一种基于模糊决策树的网络取证分析系统,以协助网络取证人员在网络环境下对计算机犯罪事件进行取证分析.给出了该方法的实验结果以及与现有方法的对照分析结果.实验结果表明,该系统可以对大多数网络事件进行识别(平均正确分类率为91 . 16 ? ) ,能为网络取证人员提供可理解的信息,协助取证人员进行快速高效的证据分析
From the perspective of property rights , the implementation of the credit system demonstrated the accounting objectives of an university , strengthened the cash basis of accounting , made continued operation of accounting and accounting assumptions phases verifiable , and enhanced the understandability , comparability and match ratio of the accounting information 从产权视角分析,学分制的实施显现了高校会计目标,强化了会计收付实现制基础,使得会计持续经营及会计分期假设具有了可验证性,提高了会计信息的可理解性、配比性与可比性质量特征。
Furthermore , in order to assure that the acquired classification rules to be accuracy as well as comprehensible , we put forward a method to compute the comprehensibility of the classification rule using attribute information gain , different to the other methods which evaluate the comprehensibility of the rule only by its simplicity . thus the output of the mining is more understandable and informational . we also do it using a niche - based ga 在此基础上,为了从现有数据中挖掘易于理解的分类规则,本文提出了一种应用属性信息增益计算分类规则可理解性程度的方法,改进了以往方法中仅依靠规则的简单度来评价分类规则易于理解性的缺点,从而使得到的分类规则包含有更多的分类信息,更加有助于用户的理解。
