  13. 13. Conversational
  14. 14. 1st gen bots are mostly passing parameters: @bot remind me to do <task> at <time> Next gen bots should be able to have a more natural conversation. But how? Moving beyond “slot filling” chats
  15. 15. Approaches to Natural Conversation 1) Machine learning / big data eg CleverBot has a huge amount of random chat data, but doesn’t understand it. You really need a two-sided bot for this to work. example: customer support with agents responding to customers 2) Understanding / AI Parsers, NLP and extracting and acting on the meaning. Logic variables, decisions. 3) Human supervision human supervision of incoming data. 4) Blended approach Mixing the above to get the best of all worlds
  16. 16. NLP and NLG Natural Language Processing works well for reducing down many possible inputs Certainly! When would you like to go? When do you want to go? Natural Language Generation to produce a variety of interesting replies Hi! I’d like to buy a ticket Do you sell tickets to ... When is the next show? Are there any tickets left? We sure do! How many would you like? { item: ticket intent: buy }
  17. 17. Humans are good at understanding the question
 filtering and identifying and understand what the question is Bots can be great at answering those questions 
 with examples, images, and content that can be re-used and optimized. Admin UI Key here is good Admin UI so humans can respond quickly. Async vs Sync replies It’s ok to say “I’ll get back to you” depending on the context. As long as you have something else to fill in the gaps. Supervised Bots - “Artificial AI”
  18. 18. Chatbot Learning Feedback Loop User says something Teacher responds System learns
  19. 19. Art and science Chat scripts need to be something writers can use. Bots can require a lot of code/content, so the chat scripting language needs to be readable. (eg Chatscript will reduce Wordnet syntax to ~emolike ) Admin / Visual UIs over code editors The “admin UI” can also be the scripting environment - simply by replying to customers you are “training” the bot. Dialog editors, spreadsheets and interactive fiction authoring ala Twinery.org Chat app development tools
  20. 20. Personality
  21. 21. 1. What is the bot’s objective? 2. What type of information are you getting from the user? 3. I don’t like chatting with boring people, … so why would anyone want to chat with a boring bot? Your bot should be interesting!
  22. 22. The Donald the most spectacular bot persona in the world
