StepsReferences

Either

Press Classify in the Task View - Task Details panel actions button list.

Or

Press Run New Classification from the left-hand button bar Classification sub-menu.

A "Starting classification for task <task-id>" notification is presented in the page header.

A "Classification is RUNNING" notification follows once the Classification Service has received the task details.

In the initial stage of classification, the task content branch is locked to prevent any further changes, and a warning notification is presented above the Classify action button in the Task Details panel. Whilst this is present, changes cannot be made to the content saved in the task branch, and action buttons other than Edit Task Details become inactive.

Whilst classification is running, a status icon is presented in the page header, to the right of the task identifier.

When the task classification is completed, a header notification is presented which includes a link to the Classification Report containing the classification results.

EITHER

Follow the link in the header notification to open the Classification Report.

OR

Press View Classification (completed <date-time-stamp>) in the left-hand button bar Classification sub-menu.


The Classification Report is presented in place of the Edit Panel, Concept Diagram and left-hand context panels.

This contains the following:

  • Header bar with
    • Report label showing "Classification finished at <date-time-stamp>".
    • Download Classification Results icon action button
    • Accept Classification Results icon/text action button.
  • Report change listing, with tabs for Classification Results, Removed Inferred Relationships, Inferred Not Previously Stated, and Equivalency Errors.

Each report tab shows Differences, Source, Type, Destination and Group information, and also a Preview Results button for each result row.

Each result can be previewed to confirm/review the changes prior to saving the classification results.

See Preview concept changes before saving classification results for details.

Classification results can be downloaded to your local machine in .tsv  format. The download file contains each classification result on a new line (line 1 is a header line with field labels) with tab-delimited field values for changeNature, sourceId, sourceFsn, typeId, typeFsn, destinationId, destinationNegated, characteristicTypeId, group, id, unionGroup and modifier.

Press Accept Classification Results to save the classification changes to the task.

A "Saving classification" header notification is presented whilst the results are saved to the task branch on the Terminology Server.

A "Classification saved" header notification indicates changes are now in the task branch contents, and the Accept Classification Results button becomes deactivated with the label changed to Classification saved. From this point the report can still be retrieved (via the left-hand button bar Classification sub-menu) for viewing and downloading of results, but no further changes are possible with this set of results. If further changes are made in the editor, another classification must be run to pick up those changes.
