Let's talk about Chatbots

• Users interact with the application built (by the client) that you implement.

• The application can be a simple chat window or a mobile app, or even a robot with a voice interface.

The application sends the user input to the Conversation service.

• The application connects to a workspace, which is a container for your dialog flow and training data.

• The service interprets the user input, directs the flow of the conversation and gathers information that it needs.

• You can connect additional Watson services to analyze user input, such as Tone Analyzer or Speech to Text.

The application can interact with your back-end systems based on the user's intent and additional information.

Implementation

The following steps need to be completed for an application:

• Configure a workspace: With the easy-to-use graphical environment, you set up the dialog flow and training data for your application.
• Develop your application :
• You code your application to connect to the Conversation workspace through API calls.
• You then integrate your app with other systems that you need, including back-end systems and third-party services such as chat services or social media.

Starting an application:

1. Log-in to Bluemix, Navigate to Conversation service, Create a Service and launch the tool.

2. Create Workspace :

3. Create Intents:

An intent represents the purpose of a user's input.

You can thinkg of intents as actions your users might want to perform with your application.

For example:

#hello or `#goodbye.

4. Building a Dialog:

A dialog defines the flow of your conversation in the form of a logic tree. Each node of the tree has a condition that triggers it, based on user input.

The whole conversation flow is directed using Dialogs.

5. Let's refine it!:

An entity definition includes a set of entity values that can be used to trigger different responses.

@entity

Each entity value can have multiple synonyms, which define different ways that the same value might be specified in user input.

Intents

Planning your intents:

Consider what your customers might want to do, and what the application is able to handle.

Choosing the correct intent for a user's input is the first step in providing a useful response.
