Intents and Entities and how it is important to build a chatbot 

What is the most important thing to consider when building a chatbot? Many people would say it is the design or the user interface. But the most important thing to consider is Natural Language Processing (NLP). NLP is a field of computer science and artificial intelligence that deals with the interactions between humans and computers.  

NLP is used to build chatbots that can understand human language and respond in a way that is natural for humans. To do this, NLP uses a process called contextual analysis. This process involves understanding the meaning of the words in a sentence and the speaker’s intention.  

In the world of chatbots, understanding and correctly identifying intent and entities is crucial for providing a good user experience. The intent is the goal or purpose the user has in mind when sending a message, while entities are the specific information required to fulfill that intent.  

For example, if a user sends the message “I’m looking for a hotel in New York,” the intent is “booking,” and the entities are “hotel” and “New York.” 

Natural Language Processing (NLP) is a field of computer science and artificial intelligence that deals with the interaction between humans and computers. NLP techniques are used to analyze text so chatbots can correctly interpret the user’s intent and entities.  

What are Intents and Entities?  

Intents and entities are two of the most important aspects of natural language processing (NLP). Intents are the goals or desires of the user, while entities are the specific details or objects that the user is referring to. Together, intents and entities allow NLP chatbots to understand the meaning of what a user is saying and respond in a way that is natural for humans.  

Let’s understand this through an example.  

For instance, a customer on a travel and tourism site looking to book stays might type in “Hotels in Istanbul?. The bot, understanding the text, brings backs a link with a list of hotels in Istanbul. In this example, Istanbul is the “entity” here which is specifying the place the customer is referring to.  

However, another scenario could be where the customer would have misspelled the place name – “Hotels in Istianbul“ or “Istanbul stays”.  We call this an “intent”- the customer wants to land on the “entity” -Istanbul hotels, even though she has written something else.

There are two types of intent: transactional and non-transactional. Transactional intent is when the user wants to buy something, book a service, or ask for information. Non-transactional intent is when the user is just looking for a general conversation. There are also two types of entities: system and user. System entities are the things that the chatbot knows about, such as products, services, and locations. User entities are the things the user refers to, such as specific objects or people. Intents and entities are essential because they allow NLP chatbots to understand the meaning of what a user is saying. Without them, chatbots would not be able to understand the user’s intentions or the specific details they are referring to. This would make it very difficult for chatbots to provide valuable responses to users. How important is it to have intents and entities in a chatbot?  

 How to create intents and entities in a chatbot?  

There are many ways to create intents and entities in a chatbot. One way is to use a software development kit (SDK) that provides pre-built NLP models. Another way is to use chatbot-building tools such as Talkk.ai, which allows you to create intents and entities without having to write any code.
