The power user can set the following preferences for the Tag Cloud component.
- Data source controls:
Select from the available data sources in the drop-down list, and then click
Update data source to bind your selection to the
component.
- Keyword attribute
name: Type the name of the attribute the tags will be drawn from. If you
enter an attribute that is not enabled for multi-select, it will not support
user refinements, and you will see the following message:
- Enable end user refinements: Check to allow end users to drill down on tags in the tag cloud. If the attribute is not enabled for multi-select, this option is not available.
- Tag weighting
algorithm: Choose one of the following to determine the significance of a
tag:
- Frequency: If this option is selected, the tags in the tag cloud are sized to represent the number of records associated with the related attribute value. The terms with the largest font size are associated with the greatest number of records.
- Relevancy: If this option is selected, tags in the tag cloud are sized to represent the number of records associated with the tag, and then are weighted relative to their uniqueness in the matching record set. Terms that appear throughout the index are less relevant, and appear smaller, than those that appear only in the matching records. This strategy is recommended if certain terms appear on most records in the index, to ensure that these common terms are displayed less prominently in the tag cloud.
- Maximum number of keywords: Specify the maximum number of attribute values to display in the Tag Cloud component. The default is 30.
