Bot. You said bot? Let build bot then! - Laurent Ellerbach
1 like77 views
Bot is a new fashion word. This session will explain you what’s a bot, what’s not a bot, how to build a bot using the Microsoft Bot Framework, how to include language recognition using LUIS.ai. The session will be illustrated by a real bot built to connect various information from my own house, garden, wine cellar and health as well as a real production Lego bot!

- 4. Bots are not
- 5. Bots are not: Artificial Intelligence (AI) • Bots can be simple task automation utilities • Example: Password reset bot. There’s no AI here. Just ask a couple of security validation questions, then reset the password • They may have AI as well, if the scenario applies
- 6. Bots are not: Natural language only • The more your bot depends on natural language, the riskier the user experience becomes. Typing isn’t always the best option. • Move away from natural language as quickly as possible in the navigation. • “Drive” the user as much as you can (menus, choices, etc) • Typing a lot on a mobile device: Bad experience • Example: AzureBot “stop vm1” is a command, not natural language. Less typing = better
- 7. Bots are not: Text interfaces only • Bot channels are evolving quickly to support richer experiences: Media, buttons, custom controls. These are coming. Text is not the best experience for everything, sometimes all you want is a button, or an image, or a link… • Examples: • Skype allows audio and 3D bots as well. • Slack, Facebook and Skype have buttons/custom UIs
- 8. So… what are bots?
- 9. Bots are apps. Really. That’s it.
- 10. Bots are apps • They solve problems, like apps • They are cross platform, you can run them anywhere, on any device • They are actually easier to build and deploy across platforms than apps • Very similar capabilities: Push notifications? Check. • You can publish your bot instantly on Facebook, Skype, Slack, Kik, email, custom hardware devices, anything.
- 11. Where to start? • https://dev.botframework.com/ • One platform for multiple channels • Same code, can be specific per channel as well • Fully REST API

- 17. How do we build great bots? 1. Start by asking what problem are we trying to solve. Refine until it looks like a tangible problem and not “magic” 2. Ask how a bot will be a better experience. User experience is EVERYTHING 3. Avoid too much natural language. Careful with unrealistic expectations. Natural language recognition is limited. Menus work great. Commands work great. Buttons, etc. 4. Collect data. Pump it to Azure. Use the same architecture you would use with IoT scenarios (IoT hub, stream analytics, power BI, etc). You can only analyze and improve your bot if you’re collecting metrics for it 5. Iterate, improve

- 19. What about authentication? • Every channel generate a unique encrypted ID per user (for web, context lost when browser closed) • Authentication can be done thru any method using external webpage and calling back the bot thru web API – Example available on Github • Objects are serialized so context data stored per user
- 20. A concrete example: my house
- 21. A raspberry in the garden • RPi v2 running Linux with Mono + Atmega328 • Posting info on a Windows Gateway • Connected to Azure IoT Hub
- 22. The Sprinkler board v3 • Raspberry Pi 2 • Windows IoT Core • Code ported from .NetMF • Not that straight forward (web server, UWP concept) • Offer much simpler and modern development • Added connection to Azure IoT Hub
- 23. Overall architecture of the garden 433MHz receiver ATmega328 sensors SQL Azure Azure Event Hub + Stream Analytics Web App + Javascript Browser sprinkler Netduino running .NET Microframework Gateway App IaC – Azure Resource Manager json deployment Recommen- dation workflow Automation and Machine Learning APIs

- 25. Natural language recognition • Part of Azure Cognitive services • Natural language recognition • Few native languages supported so far • http://www.luis.ai
- 26. Integration of external services • Magic of API • Netatmo connected thermostat, getting temperature, programs, changing presence mode • Endless possibilities of integration (my next steps: wine cellar inventory, weight…)
