Introduction to Watson Assistant
Learn the basics of the Watson Assistant Service
IBM Watson Assistant is an AI-powered virtual agent that provides customers with fast, consistent, and accurate answers across any messaging platform, application, device, or channel. Using AI and natural language processing, Watson Assistant learns from customer conversations, improving its ability to resolve issues the first time while removing the frustration of long wait times, tedious searches, and unhelpful chatbots.
With Watson Assistant, you can build conversational interfaces into any application, device, or channel. Most virtual assistants try to mimic human interactions, but Watson Assistant knows when to search for an answer from a knowledge base, when to ask for clarity, and when to direct someone to a human. Like a human personal assistant, the assistant you build helps your customers perform tasks and answer questions. To accomplish this, you define actions for the assistant.
An action represents a discrete outcome that you want your assistant to be able to accomplish in response to a user’s request. An action comprises the interaction between a customer and the assistant about a particular question or request. This interaction begins with the user input that starts the action (for example, I want to withdraw money). It might then include additional exchanges as the assistant gathers more information, and it ends when the assistant carries out the request or answers the customer’s question.
Here’s a video to introduce Watson Assistant.
Why use Watson Assistant?
Virtual assistants, or chatbots, go far beyond the gimmicky approach that they are often associated with. You can use bots to set appointments, call a car, and so on. It’s not a replacement for search. Amazon Echo and Google Home are excellent examples of virtual assistants. There is no interface, so having a well-structured dialog to talk through is essential.
A couple of instances of where Watson Assistant excels are customer self-service and employee self-service. Watson Assistant:
- Knows when to provide a direct answer to a common question or reference more generalized search results for something more complex
- Hands off the issue to a human agent when it’s something the virtual assistant can’t handle. The new (after October 8, 2021) Watson Assistant instance integrates seamlessly with Genesys, Nice inContact, Twilio, or your own agent.
- Integrates with a phone number to let the user talk to the assistant. Watson Assistant generates a phone number or integrates with an existing SIP provider such as IntelePeer, Genesys, or Twilio.
- Integrates directly with end-channels such as Slack or Facebook Messenger so that you can handle requests wherever it is most convenient for your users
- Stores data within user interactions that can be used to guide and personalize the experience over time
The following figure shows Watson Assistant architecture that’s common for all implementations. In this architecture:
Users interact with the assistant through one or more of these integration points:
A web chat code snippet that runs in your existing website
A virtual assistant that you publish directly to an existing third-party messaging platform, such as WhatsApp with Twilio, Slack, or Facebook Messenger
A voice assistant that the user accesses over the phone
A custom application that you develop, such as a mobile app or a robot with a voice interface
The assistant receives user input and routes it to the dialog skill.
The dialog skill interprets the user input further, then directs the flow of the conversation. The dialog gathers any information it needs to respond or perform a transaction on the user’s behalf.
Any questions that cannot be answered by the dialog skill are sent to the search skill, which finds relevant answers by searching the company knowledge bases that you configure for the purpose.
A typical approach used when deploying Watson Assistant
This section covers the terms that you need to know as you follow the learning path to use Watson Assistant in your applications.
|Assistant||Directs requests down the optimal path for solving a customer problem. Add skills so that your assistant can provide a direct answer to a common question or reference more generalized search results for something more complex.|
|Action||Comprises the interaction between a customer and the assistant about a particular question or request.|
|Step||In an action, defines the conversation turns that follow the initial customer input that triggered the action.|
|Web chat||Web chat is a code snippet that you can immediately embed in your website.|
|Phone integration||A working phone number that is automatically connected to your assistant. Or, if you prefer, you can connect the assistant to your existing infrastructure by configuring an existing Session Initiation Protocol (SIP).|
Where is Watson Assistant available?
Watson Assistant is available in both the public and private cloud.
Private Cloud: Watson Assistant is also available through IBM Private Cloud, on premises or managed, with IBM Cloud Pak for Data.
There are several SDKs available that support the various AI services. They are not limited to the following list.
