Chat bots are new apps
➤ The document discusses chat bots and how they work on various platforms. It describes chat bots as computer programs that simulate conversation with humans. It then covers different techniques for building chat bots, including retrieval-based models which select from predefined responses and generative models which create new responses. The document also explores hosting options for chat bots, including AWS Lambda and how chat bot platforms like Facebook Messenger, Microsoft Skype, and Telegram function.
Chat bots are new apps
- 1. The beginning ofa new chat-bots ecosystem. Execute custom code on the server. AWS Lambda, QuickBlox Cloud Code. Kharkiv Cloud Buzz #4, 23 Apr 2016 Igor Khomenko @ QuickBlox CHAT BOTS ARE NEW APPS
- 2. QUICKBLOX ➤ Cloud communicationbackend - API/SDK/infrastructure to build own WhatsApp ➤ Platform provides - chat using XMPP protocol, - WebRTC signalling for video/voice calling, - API for sending push notifications - user management system - data storage and more ➤ Hosted in the cloud (AWS)
- 3. SUMMARY ➤ Chat Bots:overview ➤ A taxonomy of models/techniques that are used to build conversational agents: Retrieval-Based vs. Generative ➤ How do Chat bots platform works: Facebook Messenger, Microsoft Skype, Telegram, Slack ➤ Hosting for bots ➤ AWS Lambda as a hosting for bots ➤ CloudCode architecture

- 5. Chat Bot -a computer program that simulates human conversation, or chat, through artificial intelligence(?). Typically, a chat bot will communicate with a real person. DEFINITION
- 6. • How doChat Bots make our life easier? • Why they become so popular nowadays? ASK YOURSELF
- 7. HOW DO CHATBOTS MAKE OUR LIFE EASIER “Chat bots aim to make life simpler for its users. Learning from user behaviour & preferences, chat bots should be capable of understanding your needs. Imagine ordering pizza, booking a cab, getting flight status, reading news, getting stock updates, all within just one platform? It can save so much space on your mobile phone, simple UI on a messaging platform which you already like (one platform, many services).”
- 8. WHY THEY BECOMESO POPULAR NOWADAYS • Natural: humans always liked interaction that is: 1) instant; 2) natural. • Accessible: chat apps have billions of users, you’re likely using one of them on daily basis. New home for chat bots: Facebook Messenger, Microsoft Skype, Slack, Telegram, LINE, Kik. • Light-weight: having to download another app with custom UI for every pizza shop is not what users want, apparently. Engaging a bot is as simple as messaging someone or adding a contact into a group chat.

- 11. •Retrieval-Based model •Generative models ATAXONOMY OF MODELS
- 12. RETRIEVAL-BASED MODEL • Usea repository of predefined responses to pick an appropriate response based on the input and context. • These systems don’t generate any new text, they just pick a response from a fixed set

- 14. GENERATIVE MODEL • Don’trely on pre-defined responses. They generate new responses from scratch • Based on Machine Translation techniques https://api.ai https://wit.ai https://www.luis.ai/
- 15. A TAXONOMY OFMODELS • Retrieval-based models (easier) vs Generative models (harder) • Short-Text Conversations (easier) vs long conversations (harder) • Open domain (harder) vs closed domain (easier)

- 21. HOSTING 1.Virtual server +Web framework 2.Container services: • AWS Lambda + API Gateway • Microsoft Azure WebJobs • Google Cloud (Task Queue) • Heroku 3.Hosting platforms for bots: • beepboophq
- 22. AWS LAMBDA AWS Lambdais a compute service where you can upload your code to AWS Lambda and the service can run the code on your behalf using AWS infrastructure. Cloud Code
