Updating the facet tree  After you decide the words that you want to add to the custom dictionary, create a  facet to associate these words. In this example, we create the My Facet facet to  distinguish it from the predefined facets. We create two additional facets under  My Facet called “Package” and “Troubles”, as shown in Figure 7-7. Now, you are ready to create a custom dictionary and associate the words that  you identified earlier with the new facet. This can be done either by using ICA  Studio, or more simply by creating a user dictionary within Content Analytics  administration interface. ICA Studio provides the ability to mix dictionaries and  syntax rules for sophisticated analysis, and will often be the tool of choice for  customized text analytics. You can learn more about ICA Studio in Chapter 11,  “Customizing content analytics with IBM Content Analytics Studio” on page 405. In this scenario, we use the approach of creating a custom dictionary from within  the administrative interface. We associate the words that we selected earlier with  the Package facet, as shown in Figure 7-8 on page 243. Now, whenever any of  the words are displayed in a call, the call is logged with the Package facet.
