Research On Generation Technique Of Audit Report Based On The Tracing Technique Of Data Lineage

With the development of the audit business,it becomes more and more common to use computer technology in audit business cosmically.When the audit staff carry on the specific audit business,the audit staff get the audit doubts existed in the audit data through the excution of audit methods.Then the audit staff need to validate and check the audit doubts.For the audit doubts,the audit staff require a detailed understanding of the production of the audit doubts so that they can analyse the rationality at last.This papaer realizes this function by the tracing technique of data lineage.After the completion of the audit business,the auditor needs to generate the corresponding audit report to summarize the achievement of the audit business.Based on the analysis of the audit method language,the tracing technique of data lineage in the audit domain take advantage of the function of key in the database and rewrite the audit method language by the annotation,thus this technique can trace the data lineage by the mark in the excution results finally.The tracing technique of data lineage conduct the tracing of the audit doubts in this way,then get the genaration process of the audit doubts.In order to summarize the audit business effectively,this thesis develops the generation technique of audit report to complete this function.On the basis of the analysis of the audit text,the generation technique of audit report can segment the audit text by the text segmentation technology and extract key information from the result of the segmentation,then analyse the achievement type of the audit report.According to the achievement type,the generation technique of audit report generate the corresponding content by the generation algorithm of audit report and make the summary audit report.This thesis develop the the tracing tool of data lineage and the generation tool of audit report.According to the experiments conducted in the system,the tracing tool of data lineage can get the origin of the traced audit doubts precisely.And the generation tool of audit report can generate the summary audit report according to the specific audit results by the auditors.
