An Expert System for Quality Assurance of Document Image Collections [chapter]

Roman Graf, Reinhold Huber-Mörk, Alexander Schindler, Sven Schlarb
2012 Lecture Notes in Computer Science  
This paper presents an expert system that supports decision making for page duplicate detection in document image collections.  ...  Digital preservation workflows for automatic acquisition of image collections are susceptible to errors and require quality assurance.  ...  Our hypothesis is that automatic approach should be able to detect duplicates with reliable quality. Then this method would be a significant improvement over a manual analysis.  ...

2016 Lecture Notes in Computer Science  
We were able to improve the quality of up to 42% of the models compared to using a log with imprecise labeling using default parameters and up to 87% using adaptive parameters.  ...  Moreover, using our refinement approach significantly increased the similarity of the discovered model to the original process with duplicate labels allowing for better rediscoverability.  ...  Data Quality and Noise/Deviation Filtering. Imprecise labels could also be seen as data quality problem, i.e., events having incorrect labels.  ...
