Wit.ai - what and basic how to

  1. 1. Wit.ai Natural Language for Developers
  2. 2. Chatbots will cause a near-term disruption in how businesses interact with consumers, and a long term paradigm shift in how people will interact with machines. - Matt Swanson via venturebeat.com
  3. 3. 1) Find contact info of company through the Internet 2) Call contact number 3) Navigate through a sequence of touch tones or semi-functional speech recognition steps 4) Wait on hold until a specialist is available 5) Step through a sequence of verifications to make sure it is truly you who is calling 6) Get told you need to talk with a different representative and get put on hold 7) Connect with a rep who now tries to have you navigate the Internet via voice instructions 8) Login to the company website 9) Finally, get an answer to your question 1) Open Facebook Messenger and search for the business name 2) Start the conversation by making a request 3) Receive rich media feedback (text + images + hyperlinks + voice) that answer your question VS 1-800 Support Call
  4. 4. Chatbots FTW • Standardized process • Automatic verification via profile (FB, Telegram …) • No “transferring” to “other experts” • No media breaks -> web to web (link, pictures, rich-web) • Major (!) cost savings • New marketing and up-selling tool
  5. 5. General about Bots How they learn
  6. 6. How – rule based • If this … than that ... • If the word ‘cooking’ appears in the message than look up the next meetup with that tag than send the URL to the User • If the user has talked about ‘finding a Meetup’ and then mentions ‘cooking’ than ...
  7. 7. How – machine learning • Supervised learning inputs and their desired outputs, given by a "teacher” • Unsupervised learning leaving it on its own to find structure in its input • Reinforcement learning dynamic environment in which it must perform a certain goal, without a “teacher”
