Description
Do you want to create a talking chatbot that interact with your visitors? In this tutorial, you will learn how to create Python chatbots using DialogFlow and Wit.AI platforms as well as powerful Rasa NLU and Rasa Core. DialogFlow, Wit.AI and Rasa provide several Natural Language Processing functions that parse user input and match them to the right response. Implementing NLP in your bot can be pretty difficult, but these platforms make it much easier to create a Facebook Messenger bot or a website chatbot.
DialogFlow (formerly Api.AI, Speaktoit) is a Google developer of human–computer interaction technologies based on natural language conversations. Dialogflow runs on Google Cloud Platform. In the DialogFlow Python tutorial, you will learn how to build a Facebook Messenger chatbot that incorporates NLP with Dialogflow and deploy it to Facebook.
Wit.AI makes it easy for developers to build Python chatbot applications and devices that you can talk or text to. Wit.AI is a natural language processing (NLP) tool that helps developers get structured data from chat or voice. Wit.AI makes it easy to build NLP into your chat bot, that learns from every interaction. If you want to build a Facebook bot even if you have not before, Wit.AI would be a great option. In the Wit.AI Python tutorial, you will learn how to train a Python chatbot using wit.AI by creating intents and entities for your chatbot data to build a Facebook Messenger chatbot.
Rasa is a powerful open source machine learning framework for developers to create contextual chatbots and expand bots beyond answering simple questions. In this course, you will study both Rasa NLU and Rasa Core.
Rasa NLU is an open-source natural language processing tool for intent classification and entity extraction in chatbots. You can think of it as a set of high level APIs for building your own language parser using existing NLP and ML libraries. he main reasons for using open source NLU are that: 1) you don’t have to hand over all your chatbot training data to Google, Microsoft, Amazon, or Facebook; 2) Machine Learning is not one-size-fits all. You can tweak and customize Python chatbot models for your training data; and 3) Rasa NLU runs wherever you want, so you don’t have to make an extra network request for every chatbot message that comes in.
Rasa Core leverages developers’ existing domain knowledge to help them bootstrap from zero training data, and adopts the interactive learning approach. With Rasa Core, you manually specify all of the things your bot can say and do. We call these actions. One action might be to greet the user, another might be to call an API, or query a database. Then you train a probabilistic model to predict which action your Python chatbot should take given the history of a chatbot conversation.

AI Enthusiast and a Software Developer with over 6+ years of development experience using multiple open source technologies. Presently, I'm freelancing Computer Vision and Chatbot Development projects.
I started my Freelance career back in 2011, have been doing multiple projects of multiple types. Since, I have a Bachelors Degree in Marine Engineering, I used to do Freelance CAD/CAM projects initially. I have always been a good self learner and still learn different things out of curiosity. When I learned enough web development, I started doing Web Development projects and used to provide Wordpress Development and SEO services back in 2012 - 2016. Then these very interesting fields of Data Science, Machine Learning and Big Data really inspired me and I started learning things about them on difference platforms like Coursera, Udemy and Udacity. I have around 30+ certificates of courses and specializations from Coursera and still doing some courses along with my freelance work. I have done a Full Stack Web Development specialization from Hong Kong University of Science and Technology and a few other courses from John Hopkins, University of California San Diego; in Big Data, Rails Development, Data Science with R and etc.
Presently I have been involved in following projects:
1) Detect area of water present inside an image of field/pond/site with Deep Learning and Computer Vision Techniques
2) Detect number of people and machinery available in a field/site with Deep Learning
3) Fashion apparel detection with Deep Learning
4) Developing an application to bulk upload training examples for a Dialogflow intent
5) Conversational application development with Python using Rasa
I do all the projects myself, so I do each and every task myself within any kind of development, i.e. from selecting the suitable model to training the model, preparing training data, serving the application with Flask, Serverless or anything, developing UI with Vue or React and etc.
