This reference architecture describes how to build an enterprise-grade conversational bot (chatbot) using the Azure Bot Framework. Each bot is different, but there are some common patterns, workflows, and technologies to be aware of. Especially for a bot to serve enterprise workloads, there are many design considerations beyond just the core functionality. This article covers the most essential design aspects, and introduces the tools needed to build a robust, secure, and actively learning bot.

Forrester Launches New Survey On AI Adoption There’s no doubt that artificial intelligence (AI) is top of mind for executives. AI adoption started in earnest in 2016, and Forrester anticipates AI investments to continue to increase. Leaders are quickly waking up to AI’s disruptive characteristics and the need to embrace this emerging technology to remain […]
A malicious use of bots is the coordination and operation of an automated attack on networked computers, such as a denial-of-service attack by a botnet. Internet bots can also be used to commit click fraud and more recently have seen usage around MMORPG games as computer game bots.[citation needed] A spambot is an internet bot that attempts to spam large amounts of content on the Internet, usually adding advertising links. More than 94.2% of websites have experienced a bot attack.[2]
Rather than having the campaign speak for Einstein, we wanted Einstein to speak for himself, Layne Harris, 360i’s VP, Head of Innovation Technology, said to GeoMarketing. "We decided to pursue a conversational chatbot that would feel natural and speak as Einstein would. This provides a more intimate and immersive experience for users to really connect with him one on one and organically discover more content from the show."
How can our business leverage technology to better and more often engage younger audiences with our products and services? H&M is one of several retailers experimenting with and leveraging chatbots as a  mobile marketing opportunity – according to a report by Accenture, 32 percent of the world (a large portion of the population 29 years old and younger) uses social media daily and 80 percent of that time is via mobile.

Consider why someone would turn to a bot in the first place. According to an upcoming HubSpot research report, of the 71% of people willing to use messaging apps to get customer assistance, many do it because they want their problem solved, fast. And if you've ever used (or possibly profaned) Siri, you know there's a much lower tolerance for machines to make mistakes.
3. Now, since ours is a conversational AI bot, we need to keep track of the conversations happened thus far, to predict an appropriate response. For this purpose, we need a dictionary object that can be persisted with information about the current intent, current entities, persisted information that user would have provided to bot’s previous questions, bot’s previous action, results of the API call (if any). This information will constitute our input X, the feature vector. The target y, that the dialogue model is going to be trained upon will be ‘next_action’ (The next_action can simply be a one-hot encoded vector corresponding to each actions that we define in our training data).
Respect the conversational UI. The full interaction should take place natively within the app. The goal is to recognize the user's intent and provide the right content with minimum user input. Every question asked should bring the user closer to the answer they want. If you need so much information that you're playing a game of 20 Questions, then switch to a form and deliver the content another way.
Ein Chatterbot, Chatbot oder kurz Bot ist ein textbasiertes Dialogsystem, welches das Chatten mit einem technischen System erlaubt. Er hat je einen Bereich zur Textein- und -ausgabe, über die sich in natürlicher Sprache mit dem dahinterstehenden System kommunizieren lässt. Chatbots können, müssen aber nicht in Verbindung mit einem Avatar benutzt werden. Technisch sind Bots näher mit einer Volltextsuchmaschine verwandt als mit künstlicher oder gar natürlicher Intelligenz. Mit der steigenden Computerleistung können Chatbot-Systeme allerdings immer schneller auf immer umfangreichere Datenbestände zugreifen und daher auch intelligente Dialoge für den Nutzer bieten. Solche Systeme werden auch als virtuelle persönliche Assistenten bezeichnet.
Forrester just released a new report on mobile and new technology priorities for marketers, based on our latest global mobile executive survey. We found out that marketers: Fail to deliver on foundational mobile experiences. Consumers’ expectations of a brand’s mobile experience have never been higher. And yet, 58% of marketers agree that their mobile services […]
User message. Once authenticated, the user sends a message to the bot. The bot reads the message and routes it to a natural language understanding service such as LUIS. This step gets the intents (what the user wants to do) and entities (what things the user is interested in). The bot then builds a query that it passes to a service that serves information, such as Azure Search for document retrieval, QnA Maker for FAQs, or a custom knowledge base. The bot uses these results to construct a response. To give the best result for a given query, the bot might make several back-and-forth calls to these remote services.
When you have a desperate need for a java fix with minimal human interaction and effort, this bot has you covered. According to a demo led by Gerri Martin-Flickinger, the coffee chain's chief technology officer, the bot even understands complex orders with special requests, like "double upside down macchiato half decaf with room and a splash of cream in a grande cup."

Aside from being practical and time-convenient, chatbots guarantee a huge reduction in support costs. According to IBM, the influence of chatbots on CRM is staggering.  They provide a 99 percent improvement rate in response times, therefore, cutting resolution from 38 hours to five minutes. Also, they caused a massive drop in cost per query from $15-$200 (human agents) to $1 (virtual agents). Finally, virtual agents can take up an average of 30,000+ consumers per month.

This is the big one. We worked with one particular large publisher (can’t name names unfortunately, but hundreds of thousands of users) in two phases. We initially released a test phase that was sort of a “catch all”. Anyone could message a broad keyword to their bot and start a campaign. Although we had a huge number of users come in, engagement was relatively average (87% open rate and 27.05% click-through rate average over the course of the test). Drop off here was fairly high, about 3.14% of users had unsubscribed by the end of the test.
If your interaction with a conversational bot is through a specific menu (where you interact through buttons but the bot does not understand natural language input), chances are you are talking to a bot with structured questions and responses. This type of bot is usually applied on messenger platforms for marketing purposes. They are great at conducting surveys, generating leads, and sending daily content pieces or newsletters.
Using this method, you can manage multiple funnels of content upgrades, and even convince your users to take the next step in the buyer journey directly within Messenger. In the example below I just direct the user to subscribe to content recommendations via Messenger, but you could push them to book a meeting with a sales rep, take a free trial or directly purchase your product.
To envision the future of chatbots/virtual assistants, we need to take a quick trip down memory lane. Remember Clippy? Love him or hate him, he’s ingrained in our memory as the little assistant who couldn’t (sorry, Clippy.).  But someday, this paper clip could be the chosen one. Imagine with me if you will a support agent speaking with a customer over the phone, or even chat support. Clippy could be listening in, reviewing the questions the customer is posing, and proactively providing relevant content to the support agent. Instead of digging around from system to system, good ‘ole Clippy would have their back, saving them the trouble of hunting down relevant information needed for the task at hand.
There are several defined conversational branches that the bots can take depending on what the user enters, but the primary goal of the app is to sell comic books and movie tickets. As a result, the conversations users can have with Star-Lord might feel a little forced. One aspect of the experience the app gets right, however, is the fact that the conversations users can have with the bot are interspersed with gorgeous, full-color artwork from Marvel’s comics. 
While AppleTV’s commerce capabilities are currently limited to purchasing media from iTunes, it seems likely that Siri’s capabilities would be extended to tvOS apps so app developers will be able to support voice commands from AppleTV directly within their apps. Imagine using voice commands to navigate through Netflix, browse the your Fancy shopping feed, or plan a trip using Tripadvisor on AppleTV — the potential for app developers will be significant if Apple extends its developer platform further into the home through AppleTV and Siri.

However, chatbots are not just limited to answering queries and providing basic knowledge. They can work as an aid to the teacher/instructor by identifying spelling and grammatical mistakes with precision, checking homework, assigning projects, and, more importantly, keeping track of students' progress and achievements. A human can only do so much, whereas a bot has virtually an infinite capacity to store and analyse all data.
Do the nature of our services and size of our customer base warrant an investment in a more efficient and automated customer service response? How can we offer a more streamlined experience without (necessarily) increasing costly human resources?  Amtrak’s website receives over 375,000 daily visitors, and they wanted a solution that provided users with instant access to online self-service.

Several studies accomplished by analytics agencies such as Juniper or Gartner [34] report significant reduction of cost of customer services, leading to billions of dollars of economy in the next 10 years. Gartner predicts an integration by 2020 of chatbots in at least 85% of all client's applications to customer service. Juniper's study announces an impressive amount of $8 billion retained annually by 2022 due to the use of chatbots.
