When an update becomes available, an update icon will appear next to the version number of the derived skill in the Skill Catalog. Additionally, its settings icon will show an alert indicator. To update a derived skill, either click the update icon and select Update, or complete the following steps:
  1. Open the skill.
  2. Click the settings alert icon to open its settings.
  3. Select the latest version of the based skill.
  4. Click Save. The derived skill will be retrained automatically.
  5. Test the skill and make any adjustments as may be necessary.
  6. Publish the skill to make its updated version available in Vantage.
Note: If you are not satisfied with the extraction statistics of a derived skill, do not publish the skill. Use its previous version instead. To use the previous version, go to the Skill Catalog, select the skill, and click Discard changes on the toolbar.
When a derived skill is updated:
  • The derived skill will inherit all the fields and rules (and their enabled or disabled states) of the base skill. New rules will be added to the derived skill as follows:
  • If any rule from the base skill is enabled in the derived skill, the new rules will also be enabled.
  • If no rules from the base skill are enabled in the derived skill, the new rules will be disabled.
  • If any fields have been deleted from the base skill, they will be preserved in the derived skill as custom fields.
  • If any rules have been deleted from the base skill, they will be deleted from the derived skill.
  • If the structure of a data catalog has been changed in the base skill, a new data catalog with the same structure will be added to the derived skill.
  • The data form layout of the derived skill will be preserved, with the new fields appended at the end of the form.
  • The derived skill will inherit the recognition settings of the base skill.
  • Skill parameters will be updated as follows:
    • If a parameter has been added to the base skill, an identical parameter will also be added to the derived skill. If the derived skill contains a custom parameter with the same name, the custom parameter will be overwritten.
    • If a parameter has been removed from the base skill, any parameter with the same name in the derived skill will become a custom parameter.
    • If a parameter has been renamed in the base skill, the derived skill will be updated as if a new parameter has been added to and an existing parameter has been removed from the base skill.
    • If the default value of a parameter has been changed in the base skill, the value of the identical parameter in the derived skill will also be changed if the user did not change its default value. Or, it will remain unchanged if the user changed its default value.
