The entities recognition can be done either by machine learning, a dictionary of possible values or some form of rules.ĭialogflow, IBM Watson Assistant and Azure Bot Service (with Language Understanding (LUIS) cloud-based API service) support intents and entities. In order to use specific details from the text such as the destination location, those platforms provide a way to define entities that will represent this information in the user’s text. For instance, a user can say: “I need a cheap flight ticket to Florida”, this can be mapped to an action of a search for a flight ticket. Intents are utterances which learns to interpret what the user might say into a category that can reflect an action in an app. The web interface is available to create and publish bots which is fairly easy to understand in the case of Azure Bot. First, you need to create a Skill and then go to Assistant to integrate it with other channels. Once you create an account, you will get video tutorials and ready to use samples to quickly get started. IBM Watson Assistant provides a good and easy to navigate user interface. Just supply a few example phrases and Amazon Lex builds a complete natural language model through which your user can interact using voice and text, to ask questions, get answers, and complete sophisticated tasks. You could make a basic Q&A chatbot with Dialogflow in a matter of hours.Īmazon Lex provides an easy-to-use console to guide you through the process of creating your own chatbot or conversational interface in minutes. The basic attributes such as Intents, Entities, Actions are easy to understand and configure. It can also respond to your customers in a couple of ways, either through text or with synthetic speech.ĭialogflow provides a web interface to create bots which makes it easy for even non-techies to create basic bots. Dialogflow can analyze multiple types of input from your customers, including text or audio inputs (like from a phone or voice recording). Using Dialogflow, you can provide new and engaging ways for users to interact with your product. Dialogflow got acquired by Google in 2016.ĭialogflow is a natural language understanding platform that makes it easy to design and integrate a conversational user interface into your mobile app, web application, device, bot, interactive voice response system, and so on. It is a completely closed-source product with APIs and web interfaces. Introduction to these Botsĭialogflow previously known as API.ai is a Google-owned developer of human-computer interaction technologies based on natural language conversations. Here’s how to choose between Amazon’s Lex, Google’s Dialogflow, IBM Watson Assistant and Azure Bot Service. Of course, there are advantages and disadvantages to each major Platform and Frameworks. Popular frameworks allow developers to build for natural language and robust customization and create bots that will integrate with a wide variety of publishing platforms. You can think of a framework as a kind of toolkit for development, with ready-made code snippets that plug into an API easily. These bot building platforms go hand in hand with bot publishing platforms, like Facebook, Slack, or Twitter, where easy-to-build bots are launched for interaction.īot frameworks, on the other hand, are more complicated. Most bot platforms allow users to create bots without any coding knowledge using drag-and-drop functionality. Frameworks make it easier to create a customized chatbot than starting from nothing, but they still require advanced coding knowledge to use.īot platforms are the easy slopes and bot frameworks are the expert-only runs. What's a Chatbot Framework?Ĭhatbot frameworks-or bot frameworks-are digital spaces where developers build bots from the ground up from predefined functions and classes. Some platforms provide an end-to-end solution while others provide components that require some programming in order to compose a bunch of API’s and services into a solution. These AI services allow simplifying building smart conversational bots. Most of the major tech companies including Google, Microsoft, Amazon, and even Facebook, as well as many rising start-ups in the field offers Natural Language Understanding and conversational AI tools as a service.
