Categorization

The Categorization tool window shows the categorization results of the last analysis carried out on the test document specified in the context bar.

Its panels are:

• Categories
• Hits/Blocks
• Rule preview

Categories panel

This panel shows the categories that were returned by the categorization process and—as a detail for each category—the rules, in the form of snippets, that determined that outcome.

There's a row for each output category.
The W symbol marks "winners", the L symbol marks "losers". "Losing" categories are those that, through scripting, were ruled out of final output, but can still be visualized in Studio.

The columns are:

Column	Description
Category/Rules	Category name or rule's condition
Label	(Only for categories) Category description
Score	The overall score of the category or, for rules' snippets, the contribution of the rule to the score
Frequency	(Only for categories) The score computed as a percentage of the sum of the scores of all the categories
Hits	(Only for rules) The number of times the rule was matched
Compound	(Only for categories) Compound score
Quality	(Only for categories) Quality check result

The quality check result appears only if the category has been set as a categorization target for the test document through annotation.

The Compound column appears only if in the Studio Settings window, the Tool Windows > Categorization > Show Compound column in categories tree configuration property is set to true. For a description of the compound score read about the CHIILD_TO_FATHER option in the Studio languages reference manual.

These are the icons used to describe quality check results:

Icon	Name	Description
	TP	True positive, the annotated target was matched
	FP	False positive, unexpected result, no annotation for this result
	FN	False negative, there were no results for the annotated target
	Quality undefined	Incomplete match between actual extractions and targets: some values match annotations, other values don't

The toolbar contains:

Icon	Name	Description
	Expand All	Expand all the categories, showing rules
	Collapse All	Collapse all the categories, hiding rules
	Search box	Search criteria
	Reset	Reset the search criteria
	Find Next	Display the results matching the search criteria in the Find Results tool windoow
	Toggle Label Visibility	Display or hide the Label column
	Toggle D Hit Categories Visibility	Display or hide losing categories
	Toggle Annotations Visibility	Display or hide the annotation toolbar

The counter at the bottom of the panel shows the number of categories.

Annotation toolbar

This toolbar allows annotating results as categorization targets for future quality checks.

Hits/Blocks panel

This panel shows all the hits of the rule that's selected in the categories panel. For every hit, it can show the blocks, that is, the rule's sub-conditions that were satisfied and thus determined the hit.

There's a row for each hit.
Score is the contribution the hit gave to the overall category score.

The toolbar contains:

Icon	Name	Description

Click a block	Highlight the text that was matched by the block in the test document inside the editor
Double-click a hit	Toggle action if the command is repeated: highlight the rule in the rules source file inside the editor or highlight the rule's hits in the test document inside the editor

Rule preview panel

This panel shows the rule that's selected in the categories panel, without the need to open the rule's source file in the editor.
