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 label.
Delete node Delete the domain
Export Taxonomy Export the taxonomy in .csv format
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 test 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.
