Hello guys, welcome to the 25th session of using Microsoft Word framework movies and cognitive services tutorials for beginners. In this session, we will see what is preferred domain in Lewis. Prepared domains attribute sets of intents and entities that work together for client applications. The prebuilt domains have been created and are ready for you to add to your Louis app. We can customize those intents and entities after adding it in our app. Currently, Lewis supports 21 private domains, here are all the state.

Note that those all are not supported by all of the languages and private domain is still under preview. Mix Microsoft is still making changes in it. Let me switch to the browser. Here I will create a new app for that. In this app, I will add indents of calendar Which includes intents for add, edit, delete find appointment. So I'm using calendar demo for this app.

Click on previous domains on the bottom. You can see that list comes as we have seen. Click on Add domain button of the calendar. Here it has been added. Let's click on embed along with none intent now it contains some more intense. Let us click on Add.

Here it contains some utterances such as echo Tuesday's calendar, visiting the location, location on Monday GPS location and Tuesday, 1pm plays etc along with utterances we can add our own utterance as well as three more any of these. Here location is an entity. We will see more about the entity next station. Thanks for watching this video. If you have any doubts, please feel free to contact me. Have a nice day.
