![]() It’s implied that we’re talking about “piano practice”. However, the second question, “Okay, what about tomorrow night then?” doesn’t specify anything about the actual event. ![]() “Hey, are you coming for piano practice tonight?” “Sorry, I’ve got dinner plans.” “Okay, what about tomorrow night then?” “That works!”ĭid you notice what just happened? The first question is straightforward to parse: The time is “tonight”, and the event, “piano practice”. A context-aware bot can remember things, and hold a conversation like humans do. This is what makes the bot truly conversational. For example, “category”, for a bot about Pokemon! We’ll dive into how to make a custom developer entity further in the post.Ĭontext: Final concept before we can get started with coding is “Context”. And then there are developer defined entities. There are system entities, provided by DialogFlow for simple things like numbers and dates. This includes stuff like dates, distance, currency, etc. ![]() Any information in a sentence, critical to your business logic, will be an entity. An intent decides what API to call, with what parameters, and how to respond back, to a user’s request.Įntity: An agent wouldn’t know what values to extract from a given user’s input. You can create as many intents as your business logic desires, and even co-relate them, using contexts. But in the end, they should all resolve to a single intent.Įxamples of intents can be: “What’s the weather like in Mumbai today?” or “What is the recipe for an omelet?” In short, a user may request the same thing in many ways, re-structuring their sentences. They’re entry points into a conversation. It maps what a user says to what action should be taken. Intents are simply actions that a user can perform on your agent. This agent connects to your backend and provides it with business logic. Or on your own app or website as well! The building blocks of DialogFlowĪgent: DialogFlow allows you to make NLU modules, called agents (basically the face of your bot). ![]() You can then deploy this bot to any platform of your choosing - Facebook Messenger, Slack, Google Assistant, Twitter, Skype, etc. It actually replaces the NLU parsing bit so that you can focus on other areas like your business logic!ĭialogFlow is simply a tool that allows you to make bots (or assistants or agents) that understand human conversation, string together a meaningful API call with appropriate parameters after parsing the conversation and respond with an adequate reply. How do you make sure your bot is actually understanding what the user says, and parsing their requests correctly? Well, here’s where DialogFlow comes in and fills the gap. ![]() Natural language understanding (NLU) has always been the painful part while building a chatbot. While understanding the intricacies of human conversations, where we say one thing but mean the other, is still an art lost on machines, a domain-specific bot is the closest thing we can build. If you’ve been keeping up with the current advancements in the world of chat and voice bots, you’ve probably come across Google’s newest acquisition - DialogFlow (formerly, api.ai) - a platform that provides a use-case specific, engaging voice and text-based conversations, powered by AI. ![]()
