Log window
The Log pane contains the event log for the current project and statistics related to application of FlexiLayouts and classifier performance. The event log contains messages about processes that take some time to complete, such as recognition, application of FlexiLayouts, classifier training and FlexiLayout training. These messages include notifications, warnings and error messages.
Notifications begin with the name of the operation that caused them, and end with a line containing the word "Done". The text of a notification's body is indented relative to the name of the operation. Warnings and error messages begin with an icon, which is followed by the numbers of pages on which the errors occurred, followed by the text of the message.
The Log is displayed automatically when any messages other than notifications about the beginning and completion of operations are added to the event log. You can close the log and open it at any other time by clicking Log on the View menu or pressing Alt + 6.
You can save parts of the log or the entire log by right-clicking inside the Log pane and clicking one of the following items on the shortcut menu:
- Copy Selected Text to copy selected text to the clipboard.
- Export Log to save the entire log as a text file (*.txt).
Log entries and statistics for classification
When a classification task begins, the Classifying pages... notification appears in the event log. This is followed by information about classification results for every page:
- An icon indicating the degree of classification confidence (displayed only for classified pages);
- Page number;
- Status (Classified / Not classified);
- The class or classes of the page as determined by the classifier;
- The reference class;
- Results from an automatic classifier (if an automatic classifier is used).
When a classification task completes, general statistics are added to the event log. This includes the number and percentages of images classified with various degrees of confidence and statistics on images that could not be classified.
- Succeeded indicates that a classification result is a perfect match for a reference value.
Note.The statistic for successfully processed pages includes pages for which no reference class was specified and no class was determined by the classifier. - Classified as extra indicates that the only classification result contains a reference class from the Extra classes of this classification result set.
- Fuzzy classified indicates that the classification result contains two or more classes, including the reference class.
- Not classified indicates that the classifier failed to determine the class even though a reference class was specified for the image.
- Wrongly classified indicates that the classification result contains at least one class, but the reference class was either not specified or is different from the classification result.
Log entries and statistics for FlexiLayout application
When the program begins applying a FlexiLayout, the Matching the FlexiLayout... message appears in the event log. This is followed by information about application results:
- An icon indicating the degree of confidence in the FlexiLayout variant detection result.
- The page's number in the batch.
- Status (Matched / Unmatched).
- The name of the applied FlexiLayout variant and the page's number in the document.
- The reference FlexiLayout.
- Image analysis statistics, including the number of blocs detected with various degrees of confidence.
Messages from this group are indented relative to general information about application results.
Event log entries are followed by statistics for all processed pages, grouped by blocks from the FlexiLayout. These statistics include the amount of pages for each block and the numbers of pages on which the block was found with various degrees of confidence.
- Succeeded indicates that the detected block region matches the reference region and recognition objects of the corresponding type also match.
- Fuzzy matched indicates that the detected region of the block largely matches the reference region.
- Wrongly matched indicates that the detected region of the block is largely different from the reference region.
- Not matched indicates that there is a reference region for the block on the image, but no matching region was detected.
- Excessively matched a region was detected for a block even though there is no reference region.
The confidence score of a region match is determined by evaluating how well sets of recognition objects of the same type as the block match each other. The confidence score of a region match for tables is determined based on how well individual cells match.
