How to use WCS
1. Train Watson to understand your users' input with user example utterances– Intents: A group of examples that a user might say to communicate a specific
goal or idea that the user wants– User examples: Questions collected by the client to support the client’s use
case.– Example:
• Intent: #hotel_hours• User Examples
• Hours for pool• What are the hours of the gym?

How to use WCS
2. Identify the terms that may vary in your users' input– Entities: Watson's way of handling significant parts of an input that should be
used to slightly alter the way it responds to the intent.• Examples:
• Entity Name: @hotel_amenity• Entity Value: pool, gym• Synonym: swimming pool, fitness center

How to use WCS
3. Create the responses to your user's questions: – Dialog Builder: Used to build dialog chat flows– Dialog: the logical flow that determines the responses your bot will give
when certain intents and/or entities are detected.
4. Test and Improve– Use the Try it out panel– Improve component
