Classes

The Classes tool window allows managing the classes of output information of the project, that is:

• The domains to which categorization rules can give points
• The templates of the extraction records whose fields can be set by extraction rules

The tool window has two panels:

• Taxonomy
• Templates

Taxonomy

The Taxonomy panel displays and allows managing the project taxonomy, that is, the tree structure in which categorization domains are defined.

The default view is a table in which each row represents a first-level domain. Rows can then be expanded to reveal descendant domains.

Columns are:

Name	Description
Name	Domain name
Label	Domain description
Rules	Number of categorization rules that give points to the domain
Ann	Number of times the domain was annotated as a target output category for test documents
Shortlist	Selection check box

Info

Selected domains become part of the list from which you can choose when annotating target categories for a test document in the Project tool window or in the editor.

Context menu

Name	Description
Expand Node	Expand the current node. Available only if there are descendant domains.
Compress Node	Collapse the current node. Available only if there are descendant domains.
Add Node	Add a sibling domain, that is, a domain on the same level of the hierarchy.
Add Child	Add a child domain.
Edit Node	Modify domain name and/or description.
Delete Node	Delete the domain.
Annotate XXXX for file YYYY	Annotate domain XXXX as a categorization target for the test document YYYY that's currently opened and selected in the editor.

When one or more domains are checked, the context menu has also the following commands:

Name	Description
Annotate checked nodes for file XXXX	Annotate the checked domains as a categorization target for the test file XXXX that's currently opened and selected in the editor.
Annotate checked nodes for all opened files	Annotate the checked domains as a categorization target for all the test files currently opened in the editor. Option available for more than one file opened

Add Node, Add Child and Edit Node commands open the Taxonomy Node dialog box. In it, the Generate command creates a suggested name for the domain. You can overwrite the suggestion and give the domain the name you prefer.

Note

The Taxonomy tool window and the taxonomy.xml file are synchronized, so each change made on one side is soon reflected on the other.

Other available mouse commands

Command	Description
double-click an item in the Name columns or in the Label column	Open the Taxonomy node window, where it is possible to modify the Name or the Label value.
double-click an item in the Rules column	Open the Rule files window showing the list of files containing rules that give points to the domain. double-click on a file name to open the file in the editing area.
double-click an item in the Ann column	Open the Annotation files window showing the list of files containing annotations of the domain. double-click on a file name to open the file in the editing area.

Info bar

The info bar shows the total number of nodes and the number of selected nodes.

Templates

The Templates panel displays project's extraction templates.

The default view is a table in which each row represents a template. Rows can then be expanded to reveal templates' fields.

Columns are:

Name	Description
Name	Template or field name
Attributes	Field attributes
Rules	Number of rules that extract the field. For templates, the number if bracketed and represents the sum of the counters for template's fields.
Ann	Number of times the field was annotated as a target output extraction for test documents. For templates, the number is bracketed and represents the sum of the counters of template's fields.
Shortlist	Selection check box

Info

Selected fields become part of the list from which you can choose when annotating target extractions for a test document in the editor.
