摘要
[目的/意义]设计真实性风险检测方法,并通过实验进行验证。[方法/过程]首先,界定数字保存真实性的含义及其风险类型;其次,设计真实性风险的元数据;再次,基于CNKI采集实验样本,设计检测算法;最后,编制代码并进行检测,统计检测结果。[结果/结论]通过实验,CNKI中数字对象在一些检测点上存在真实性风险。[局限]文章中所设计的真实性风险型元数据并不十分完善,在一定程度上会影响检测结果的准确性。
[Purpose/significance] A method for detecting the authenticity risk is designed and tested through an experiment.[Method/process] First,this paper defines the connotation of authenticity of digital preservation and its risk types. Secondly,the metadata of the authenticity risk are designed. Thirdly,the paper extracts test samples from CNKI and designs the detection algorithm. Finally,the paper runs the codes for detection,and calculates the results. [Result/conclusion] Through the experiment,the digital objects in CNKI have authenticity risks on some detection points. [Limitations] The metadata of authenticity risks designed in this paper are not perfect enough,which may affect the accuracy of the test results to a certain extent.
