# Configuring the Tag Cloud component

This topic describes how to configure the Tag Cloud component.

You configure a Tag Cloud component via its Configuration Options dialog:

To configure the Tag Cloud component:

1. After adding a Tag Cloud component to a page, click its .... button and then click Preferences.
2. In the Tag Cloud edit view, select from the available data sources in the drop-down list, and then click Update data source to bind your selection to the component.

3. In the Keyword attribute name field, enter the name of the attribute the tags will be drawn from. The attribute must be enabled for multi-select. If you enter a multi-select attribute, Discovery Framework will verify it by showing a double-check icon next to the attribute name, as in this example:

   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:

4. Check the Enable end user refinements box 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.
5. Select a Tag weighting algorithm 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.
6. In the Maximum number of keywords field, specify the maximum number of attribute values to display in the Tag Cloud component. The default is 30.
7. Click Save Preferences to save your changes.
