# \(Legacy\) Activate the NLU Workbench

Activate the following plugins to activate the NLU Workbench.

## Before you begin

Role required: admin

## About this task

Starting with the Brazil release, Natural Language Understanding is being prepared for future deprecation. It will be hidden and no longer activated on new instances but will continue to be supported. For details, see the [Deprecation Process \[KB0867184\]](https://support.servicenow.com/kb_view.do?sysparm_article=KB0867184) article in the Now Support Knowledge Base.

Activate the following plugins if they aren't already active in your instance.

NLU Workbench - Corecom.glide.nlu

</td><td>

Installs the required tables for persisting NLU models that are created using the NLU Workbench.

</td></tr><tr><td>

NLU Workbench com.snc.nlu\_studio

</td><td>

Enables the creation of Natural Language Understanding \(NLU\) models. These models can understand the intent \(action\) and entities \(details about the action\) for a given user utterance. Any ServiceNow application can invoke an NLU model.Requires the NLU Workbench - Core plugin and the NLU Common Model plugin.

</td></tr><tr><td>

Predictive Intelligence com.glide.platform\_ml

</td><td>

Enables the NLU Service APIs used for model creation and inference. Enables the creation of machine learning solutions that are trained on data in your instance. Provides frameworks for classification, similarity, and clustering. A trained solution can be invoked by any application by using a prediction API.

</td></tr><tr><td>

NLU Common Modelcom.glide.nlu.model

</td><td>

Packages all language NLU common models. Also includes commonly used pattern entities that can be imported and used in any NLU model in the NLU Workbench. Commonly used patterns like email, phone, and ServiceNow specific pattern entities such as INT, RITM are made available. Requires the NLU Workbench - Core plugin.

NLU Active Learning-Propertiescom.glide.nlu.active\_learning\_properties

</td><td>

Enables the nlu\_admin to configure the system properties for the Expert Feedback Loop application. If you don't use the Expert Feedback Loop application, this plugin is not used and can safely be ignored. For more information about the system properties for the Expert Feedback Loop, see the [NLU Expert Feedback Loop](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/brazil/markdown/intelligent-experiences/nlu-service/nlu-expert-feedback-loop.md) documentation.

</td><td>

Delivers the Intent Discovery feature, which identifies user intents by analyzing incident/case data. Use this application to help identify which intents to model and build for Virtual Agent conversations to attain maximum deflection.

</table>## Procedure

1.  Navigate to **All** &gt; **System Applications** &gt; **All Available Applications** &gt; **All**.

2.  Find the following plugins using the filter criteria and search bar: NLU Workbench - Core \(com.glide.nlu\), NLU Workbench \(com.snc.nlu\_studio\), Predictive Intelligence \(com.glide.platform\_ml\), and NLU Common Model \(com.glide.nlu.model\).

    You can search for the plugin by its name or ID. If you cannot find a plugin, you might have to request it from ServiceNow personnel.

3.  Select **Install** to start the installation process.

    **Note:** When domain separation and delegated admin are enabled in an instance, the administrative user must be in the **global** domain. Otherwise, the following error appears: `Application installation is unavailable because another operation is running: Plugin Activation for <plugin name>.`

    You will see a message after installation is completed. For information about the components installed with a plugin, see [Find components installed with an application](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/brazil/markdown/platform-administration/find-components.md).
