If you configure your chatbot for multiple languages, you do not translate topic and entity names into other languages because they are internal application values.

1. In the navigation pane of App Studio, click Channels.
2. In the Current channel interfaces section, click the icon that represents your existing Digital Messaging or Alexa channel.
3. In the channel, click the Behavior tab.
4. To enable the advanced configuration mode, in the Text Analyzer section, select the Use advanced configuration checkbox.
   In the advanced configuration mode, you configure the advanced text analyzers in the system that use NLP and adaptive analytics. If you do not use advanced configuration, you configure the default text analyzer that exactly matches user input to a response. For more information, see Exploring text predictions and text analyzers.
5. In the Text Analyzer section, click Edit topics for the text analyzer that you want to edit.
6. In the Edit topics window, click Add item.
   A topic is the general subject, the intent of a voice command, or a text message that the system detects using text analysis.
7. If you configure multiple languages for the chatbot, select a language.
   If your channel does not include a translation for the fields in the selected language, then the system will use placeholder text specified in the default language for those fields.

   Note: If you translate text into another language, the system creates a new language-specific ruleset only if the ruleset does not exist for the language already. If the ruleset already exists and is locked, to translate your text, ensure that you first unlock the ruleset in your application.
8. In the table columns, specify a topic and matching criteria for the selected language:
   • In the Topic field, enter the natural language processing topic for the IVA to use as the response. The NLP text analyzer determines the topic based on criteria that either matches exactly, matches approximately, and/or never matches the user input.
   • In the Approximate match field, to configure the IVA to look for approximate matches in the user input, enter the words and phrases that you want to use, and then separate them with commas. For example, for an initial greeting responses, enter: hello, good morning.
   • In the Must match field, to configure the IVA to look for specific items in the conversation content, enter the words and phrases that you want to exactly match in the topic, and separate them with commas. For example, for an initial greeting response, enter hi.
   • In the Never match field, enter comma-separated words or phrases to always ignore when matching for the topic. For example, for an initial greeting response to never match a goodbye greeting, enter bye.
   For example: The following figure shows the configured topics for the German language for a chatbot:
