Pre-built Virtual Agent conversations (topics), reusable topic blocks, and ServiceNow NLU models are available for the Virtual Agent platform and various business applications, such as Customer Service Management, HR Service Delivery, IT Service Management, and more.

These pre-defined conversations help users with common self-service tasks in each business area, such as creating or updating cases or providing answers to frequently asked questions. Pre-built topic blocks are reusable components (similar to subflows) that perform a specific function or task and can be added to a conversation topic. Pre-built NLU models define the business-specific language understanding needed for Virtual Agent to understand and process user requests. Each NLU intent in a model maps to a single Virtual Agent conversation topic.

Summaries of pre-built topics and topic blocks

For more information on the Virtual Agent pre-built topics and topic blocks provided by various ServiceNow applications, refer to the documentation for those applications. For example, the CSM, HRSD, and ITSM applications provide information on their pre-built topics in the following sections:
Note: The plugins for the CSM, HR Service Delivery, and ITSM predefined conversations also install their pre-built ServiceNow NLU models and topic blocks. The Glide Virtual Agent plugin installs the pre-built NLU model for setup topics, as well as platform topic blocks.
After installing the plugins or apps, you can preview (test) the topics and topic blocks using Virtual Agent Designer. You can review the intents, utterances, and entities in the pre-built NLU models using ServiceNow NLU Workbench or within Virtual Agent Designer if your NLU-enabled topics are associated with intents in ServiceNow NLU models.

Working with pre-built topics and topic blocks in Virtual Agent Designer

  • Previewing topics and topic blocks – After you install the plugins for pre-built topics, admins or Virtual Agent admins can access the pre-built topics and topic blocks in the Topics page. Select the topic and in the Flow tab, click Test. Review the conversation as it runs in the test window to determine the topics and topic blocks that you want to use.
  • Using pre-built topics and topic blocks – Although pre-built topics and topic blocks are read only and can't be changed, you can reuse them by duplicating and modifying them as needed. After you test a duplicated topic and are ready to deploy it to your Virtual Agent clients, publish the topic. Similarly, after testing a duplicated topic block, publish it to make it available for use in conversation (calling) topics.

For details on creating, testing (previewing), duplicating, and publishing a topic, see Getting started with Virtual Agent Designer. For details on working with topic blocks, see Maximizing code reuse with topic blocks.

Working with pre-built ServiceNow NLU models in ServiceNow NLU Workbench

  • Reviewing a pre-built NLU model – After you install the plugins for predefined topics, you can view the pre-built models in NLU Workbench. The pre-built NLU models for ServiceNow applications define the intents, entities, and utterances used for the predefined topics. These models are also trained and published. You can also review the utterances for a pre-built model in Virtual Agent Designer. However to copy a pre-built model, you use NLU Workbench.
  • Duplicating pre-built NLU models – Although pre-built NLU models are read only and can't be edited, you can Duplicate an NLU model pre-built NLU models to create your own NLU models and Import an NLU intent from pre-built models or other NLU models that you create in NLU Workbench.
