Master Google Dialogflow ES: Build Smart Chatbots

Explore Google Dialogflow, a natural language understanding platform for building conversational AI chatbots, and learn to access the console, sign in, and create your first agent.

Explore how Dialogflow uses natural language processing to classify user input into intents, such as default welcome and default fallback, using training phrases and text responses.

Learn how Dialogflow ES extracts entities from user queries using system, custom, and combined entities to capture numbers and directions within intents.

Learn to extract direction from user queries by creating a custom direction entity with synonyms like backward and forward, and map it to an intent in Dialogflow ES.

Demonstrates composite and multi-entity extraction in Dialogflow ES by building intents that capture steps and direction from a single query using system and custom entities.

Convert composite entity values into an object by assigning a column and variable name for each entity, then train to extract five forward steps for backend or webhook usage.

Understand how context drives Dialogflow ES conversations by using input and output contexts to gate intent matching, with examples like awaiting name and awaiting mobile.

Understand fulfillment as the webhook communication between Dialogflow and your server, where user input triggers a server request, data processing via databases or APIs, and returned response to the user.

Connect Dialogflow to your own server using a webhook; your server processes requests, interacts with APIs or databases, and returns responses to users via Dialogflow.

Explain Dialogflow fulfillment with the S version webhook, building a Flask route to handle post requests and respond with JSON, and using session vars to manage name and mobile number.

Build and test a Dialogflow fulfillment workflow by extracting parameters from output context, retrieving and preserving session parameters, and integrating with a webhook to power a Q&A chatbot.

Connect a Dialogflow agent to external channels through integration, using credentials and tokens for Telegram, Slack, and Facebook Messenger.

Learn how custom integration uses webhooks and Dialogflow APIs to connect platforms like Telegram and WhatsApp, detect intents and entities, and deliver channel-compatible responses from a single server.

Explore the knowledge connector beta in Dialogflow ES to upload PDFs, CSVs, or web links and answer questions from knowledge rather than intents, and learn to enable beta features.

Explore Dialogflow ES settings to configure the agent: rename, description, languages, ml options, export and import, environments, sharing, and sentiment analysis, with notes on language replication and version publishing.

Explore training, validation, history, and analytics in Dialogflow ES, and improve your agent using conversation histories, pre-built agents, and smart small talk.

Build intents and responses, set default welcome and fallback messages, and train the agent to test the conversation flow. Create intents for store hours, shipping policy, contact details, and ratings.

Learn to wire intents with context in Dialogflow ES by setting input and output contexts and lifespans, debug flows, train settings, test the FAQ chatbot, and prepare for Telegram integration.

Build a question-and-answer chatbot with Dialogflow ES using Python and Flask, implementing fulfillment and webhooks to run a five-question quiz across difficulty levels, with ngrok and Telegram integration.
