Key Improvement Ideas in Microsoft Bot Framework
Under are some vital Improvement Ideas in Microsoft Bot Framework:
Actions and Turns
All of the interactions between customers and bots are referred to as actions. The interplay could occur within the type of pictures, audio, video, textual content, and many others. In regular human dialog, folks communicate one by one to precise their opinion. Equally, in bot dialog, the bot responds to the person when the bot flip got here. Typically, initially of a bot dialog, the bot greets the person. Primarily based on the person’s question or motion, the bot responds to the person utilizing the information.
Occasion-Pushed Conversations
The bot does event-driven conversations with the assistance of an exercise handler. Primarily based on the exercise or sub-activity sort, the bot decodes which exercise handler will deal with that exercise. For instance, everytime you add a brand new member to the bot dialog OnMembersAddedAsync() will get referred to as to deal with the user-welcoming logic.
Managing State and Storage in Bots
Microsoft Bot Framework SDK supplies state administration performance and a storage layer to handle the information storage and states effectively. Sustaining state helps in having higher dialog stream as we are able to save the supplied by customers within the earlier turns which could be very useful in a multi-turn dialog. Relying on the kind of knowledge, funds, and requirement, we are able to use completely different knowledge storage providers reminiscent of Reminiscence Storage, SharePoint On-line, Azure SQL, Cosmos DB, Azure Blob storage, and many others. for storing knowledge.
Bot Templates
Microsoft Bot Framework supplies a number of templates for creating bots in C# and Python. An empty bot template supplies a fundamental code construction for the bot and greets the person. The echo bot template supplies the performance of echoing the textual content entered by the person. The core bot template supplies LUIS, Customized Query Answering capabilities, part dialog, and youngster dialog to successfully handle person conversations.
Intents, Entities, and Utterances
Intent is a job that the person needs to carry out. Entities are vital data or key phrases in a textual content. Utterances are the inputs given by the person. For instance, in a flight reserving situation when a person supplies enter to a bot as “Ebook a flight from Mumbai to Pune for
twenty fourth Might 2023”. Right here, reserving a flight is intent, Mumbai and Pune are entities, and Reserving a flight from Mumbai to Pune for twenty fourth Might 2023 is utterance.
Dialogs & Kinds of Dialogs
Dialogs present methods to handle conversations with customers. We will go arguments or parameters to dialogs. A dialog may be began, paused, resumed, or stopped.
Dialogs are very helpful in implementing multi-turn conversations. For instance, if we wish to develop a bot that means weekend actions and extremely rated eating places primarily based on the person’s enter like their hobbies and favourite meals, we are able to use dialogs. Bot Framework supplies numerous kinds of dialogs reminiscent of waterfall dialog, immediate dialog, adaptive dialog, QnA Maker dialog, and many others. to effectively handle the dialog with customers. For instance, use a Immediate dialog to take enter from the person and validate enter.
Ideas of Bot Design
Maintain the beneath ideas in thoughts whereas designing a bot:
1. Design nice dialog stream: Customers work together with the bot in a non-linear style. They can randomly ask completely different questions primarily based on their requirement. Bots will need to have an excellent dialog stream to deal with the above state of affairs.
2. Create an excellent person expertise: An ideal person expertise helps customers to effectively talk with the bot. To create an excellent person expertise, we are able to use pictures, carousels, NLP, speech functionality, and many others. within the bot.
3. Use Wealthy person controls: Wealthy person controls reminiscent of adaptive playing cards, audio playing cards, video playing cards, steered motion playing cards, and many others. give a greater design to the bot.
Creating Convention Registration Chatbot

3. Set up the NuGet packages: AdaptiveCards and Microsoft.Bot.Builder.Dialogs.Declarative
4. Create a brand new file ConferenceBot.cs inside the brand new folder Bots within the venture. Paste the beneath code snippet within the file:
namespace ConferenceBot.Bots
{
utilizing System;
utilizing System.Collections.Generic;
utilizing System.Threading;
utilizing System.Threading.Duties;
utilizing AdaptiveCards;
utilizing Microsoft.Bot.Builder;
utilizing Microsoft.Bot.Builder.Dialogs;
utilizing Microsoft.Bot.Schema;
utilizing Microsoft.Extensions.Logging;
utilizing Newtonsoft.Json;
public class ConferenceBot<T> : ActivityHandler the place T : Dialog
{
protected readonly Dialog Dialog;
protected readonly BotState ConversationState;
protected readonly BotState UserState;
protected readonly ILogger Logger;
public ConferenceBot(
ConversationState conversationState, UserState userState,
T dialog, ILogger<ConferenceBot<T>> logger)
{
ConversationState = conversationState;
UserState = userState;
Dialog = dialog;
Logger = logger;
}
public override async Job OnTurnAsync(
ITurnContext tc, CancellationToken ct = default)
{
await base.OnTurnAsync(tc, ct);
await ConversationState.SaveChangesAsync(tc, false, ct);
await UserState.SaveChangesAsync(tc, false, ct);
}
protected override async Job OnMessageActivityAsync(
ITurnContext<IMessageActivity> tc,
CancellationToken ct)
{
Logger.LogInformation("Operating dialog with Message Exercise.");
await Dialog.RunAsync(tc,
ConversationState.CreateProperty<DialogState>
(nameof(DialogState)), ct);
}
Right here, the OnTurnAsync technique is used to course of the motion ready on the queue. The OnMessageActivityAsync technique known as for processing the message actions. The Dialog dialog will get created and the dialog state is maintained to save lots of knowledge in reminiscence.
protected override async Job OnMembersAddedAsync(
IList<ChannelAccount> ca, ITurnContext<IConversationUpdateActivity> tc,
CancellationToken ct)
{
var welcomeCard = CreateAdaptiveCardAttachment();
var welcomeResponse = MessageFactory.Attachment
(welcomeCard, ssml: "Welcome to Convention Registration!");
foreach (var member in ca)
{
if (member.Id != tc.Exercise.Recipient.Id)
{
await tc.SendActivityAsync(welcomeResponse, ct);
}
}
}
/// <abstract>
/// Adaptive Card for welcoming person
/// </abstract>
/// <returns></returns>
personal static Attachment CreateAdaptiveCardAttachment()
{
AdaptiveCard weclomeCard = new AdaptiveCard();
weclomeCard.Physique.Add(new AdaptiveTextBlock()
{
Textual content = "Convention Registration",
Dimension = AdaptiveTextSize.Massive,
Wrap = true
});
weclomeCard.Physique.Add(new AdaptiveTextBlock()
{
Textual content = "thirtieth April 2023, Pune",
Dimension = AdaptiveTextSize.Medium

FetchUserAgeAsync,
UploadProfileImageAsync,
DataProcessConfirmationStepAsync,
DataProcessingStepAsync,
};
AddDialog(new WaterfallDialog(
nameof(WaterfallDialog),
waterfallSteps));
AddDialog(new TextPrompt(
nameof(TextPrompt),
ValidateNameAsync));
AddDialog(new TextPrompt(
nameof(TextPrompt)));
AddDialog(new ChoicePrompt(
nameof(ChoicePrompt)));
AddDialog(new NumberPrompt<int>(
nameof(NumberPrompt<int>),
ValidateAgeAsync));
AddDialog(new ConfirmPrompt(
nameof(ConfirmPrompt)));
AddDialog(new AttachmentPrompt(
nameof(AttachmentPrompt),
ValidateProfileImageAsync));
The above code snippet creates waterfall steps for taking knowledge from the person.
personal static async Job<DialogTurnResult> FetchUserNameAsync(
WaterfallStepContext sc, CancellationToken ct)
{
return await sc.PromptAsync(nameof(TextPrompt),
new PromptOptions
{
Immediate = MessageFactory.Textual content(
"Please enter your identify (should include at the very least 3 characters
and at most 200 characters)."),
RetryPrompt = MessageFactory.Textual content("Invalid username"),
}
, ct);
}The above code snippet creates Textual content Immediate which takes the username. The FetchUserEmailAsync, TransportStepAsync, and FetchUserAgeAsync strategies shops identify, e-mail, and age and course of the supplied knowledge.
personal async Job<DialogTurnResult> FetchUserEmailAsync(
WaterfallStepContext sc, CancellationToken ct)
{
sc.Values["name"] = (string)sc.End result;
//logic
}personal async Job<DialogTurnResult> TransportStepAsync(
WaterfallStepContext sc
, CancellationToken ct)
{
sc.Values["email"] = (string)sc.End result;
//logic
}personal async Job<DialogTurnResult> FetchUserAgeAsync(
WaterfallStepContext sc,
CancellationToken ct)
{
if ((bool)sc.End result)
{
var promptOptions = new PromptOptions
{
Immediate = MessageFactory.Textual content("Present age:"),
RetryPrompt = MessageFactory.Textual content("Invalid age."),
};
return await sc.
PromptAsync(nameof(NumberPrompt<int>),
promptOptions, ct);
}
else
{
return await sc.
NextAsync(-1, ct);
}
} personal static Job<bool> ValidateAgeAsync(
PromptValidatorContext<int> laptop, CancellationToken ct)
{
return Job.FromResult(laptop.Acknowledged.Succeeded &&
laptop.Acknowledged.Worth > 0 && laptop.Acknowledged.Worth < 80);
}
personal static Job<bool> ValidateNameAsync(
PromptValidatorContext<string> laptop,
CancellationToken ct)
{
return Job.FromResult(laptop.Acknowledged.Succeeded
&& laptop.Acknowledged.Worth.Size > 3
&& laptop.Acknowledged.Worth.Size < 200);
}The above code snippets validate the age and identify entered by the person. The age needs to be between 0 and 80. The size of the identify needs to be between 3 and 200.
