5.5.1 Enabling the rule-based categories feature 5.5.2 Configuring rules for rule-based categories To use the rule-based categories feature, you must enable the rule-based  categorization type. Rule-based categorization is enabled for the collection by  default.  Document clusters:  To use document clustering, select  Rule-based and  Document clusters  as the categorization type when creating the collection.  For further information about document clustering, see 9.6, “Document  clustering” on page 330. In addition, if you want to add the query that you built from the content analytics  miner, you must enable both the “Add rules to categories” and “Rebuild the  category index” application user roles. By default, these user privileges are not  enabled. Therefore, you must explicitly enable the roles by using the  administration console. Configuring the application user role:  See “Configuring application roles” Appendix A of the previous version of the book for further details about  configuring the application user roles. The previous version of the book can be  downloaded from the additional material associated with this book. See  Appendix B, “Additional materi al” on page 567 for details. After you enable the “Add rules to categories” feature, an icon is displayed in the  content analytics miner toolbar (Figure 5-56). With Content Analytics, you can define a rule category that is either based on  Uniform Resource Identifier (URI) patterns or Document content rules. You can  use the query that you build to define the Document content rules and easily add  a category rule from the content analytics miner.  136  IBM Watson Content Analytics: Discovering Actionable Insight from Your Content Figure 5-56 Adding the current rule as a new category rule icon
