The **Log** pane contains the event log for the current project, along with statistics on FlexiLayout application and classifier performance. The event log records messages about processes that take some time to complete, such as recognition, FlexiLayout application, classifier training, and FlexiLayout training. These messages include notifications, warnings, and error messages. ## How log messages are formatted Notifications begin with the name of the operation that caused them and end with a line containing the word `Done`. The body text of a notification is indented relative to the operation name. Warnings and error messages begin with an icon, followed by the numbers of the pages on which the errors occurred, and then the text of the message. ## Open and close the Log pane The **Log** pane opens automatically when the event log receives any message other than a notification about the start or completion of an operation. To close the pane or reopen it later, click **Log** on the **View** menu or press **Alt+6**. ## Save the log To save part of the log or the entire log, right-click inside the **Log** pane and click one of the following items on the shortcut menu: * **Copy Selected Text** – Copies selected text to the clipboard. * **Export Log** – Saves 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. The log then records the following 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. These include the number and percentage of images classified with various degrees of confidence, along with statistics on images that could not be classified. | Result | Meaning | | :---------------------- | :------------------------------------------------------------------------------------------------------------------------------------------------------ | | **Succeeded** | The classification result is a perfect match for the reference value. | | **Classified as extra** | The only classification result contains a reference class from the **Extra classes of this classification result** set. | | **Fuzzy classified** | The classification result contains two or more classes, including the reference class. | | **Not classified** | The classifier failed to determine the class even though a reference class was specified for the image. | | **Wrongly classified** | The classification result contains at least one class, but the reference class was either not specified or is different from the classification result. | The statistic for successfully processed pages includes pages for which no reference class was specified and no class was determined by the classifier. ## Log entries and statistics for FlexiLayout application When FlexiLayout application begins, the `Matching the FlexiLayout...` message appears in the event log. The log then records the following 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 blocks detected with various degrees of confidence Messages in the image analysis statistics group are indented relative to the 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 number of pages for each block and the numbers of pages on which the block was found with various degrees of confidence. | Result | Meaning | | :---------------------- | :-------------------------------------------------------------------------------------------------------------------- | | **Succeeded** | The detected block region matches the reference region, and recognition objects of the corresponding type also match. | | **Fuzzy matched** | The detected region of the block largely matches the reference region. | | **Wrongly matched** | The detected region of the block is largely different from the reference region. | | **Not matched** | 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. ## Related topics * [Classification](/flexi-capture/fls/classification) * [FlexiLayouts](/flexi-capture/fls/template/ftemplate)
