Reading through the phrases above, we can observe they all indicate one thing — the user wants food. In all of the phrases listed above, the name or type of food is not specified but rather they are all specified as food. This is because we want the food to be dynamic value, if we were to list all the food names we certainly would need to have a very large list of training phrases. This also applies to the amount and price of the food being ordered, they would be annotated and the agent would be able to recognize them as a placeholder for the actual values within an input.

To show you how easy it is to create an NLP conversational chatbot, we’ll use Tidio. It’s a visual drag-and-drop builder with support for natural language processing and chatbot intent recognition. You don’t need any coding skills to use it—just some basic knowledge of how chatbots work. If you decide to create your own NLP AI chatbot from scratch, you’ll need to have a strong understanding of coding both artificial intelligence and natural language processing. These models (the clue is in the name) are trained on huge amounts of data. And this has upped customer expectations of the conversational experience they want to have with support bots.

Selecting the web Demo option would generate a URL to a page with a chat window that simulates a real-world chat application. We would also modify the code of the existing cloud function to fetch a single requested as it now handles requests from two intents. At this point, we expect a user to continue the conversation with an order of one of the listed meals. Moving on to the Training Phrases section on the intent page, we will add the following phrases provided by the end-user in order to find out which meals are available. From there we add an output context with the name awaiting-order-request.

Bots without Natural Language Processing rely on buttons and static information to guide a user through a bot experience. They are significantly more limited in terms of functionality and user experience than bots equipped with Natural Language Processing. In this step, we load the data from the data.json file, which contains intents, patterns, and responses for the chatbot.

Selecting NLP Techniques

Besides enormous vocabularies, they are filled with multiple meanings many of which are completely unrelated. NLP-powered virtual agents are bots that rely on intent systems and pre-built dialogue flows — with different pathways depending on the details a user provides — to resolve customer issues. A chatbot using NLP will keep track of information throughout the conversation and learn as they go, becoming more accurate over time. The stilted, buggy chatbots of old are called rule-based chatbots.These bots aren’t very flexible in how they interact with customers. And this is because they use simple keywords or pattern matching — rather than using AI to understand a customer’s message in its entirety. Tools such as Dialogflow, IBM Watson Assistant, and Microsoft Bot Framework offer pre-built models and integrations to facilitate development and deployment.
