How Do Chatbots Work?

Chatbot technology involves several components and steps. Here is a step-by-step simplified overview:

Ways Chatbot Works

  • User Input: In this step, users send messages to the chatbot through an interface or platform.
  • Input Processing: After receiving the input, chatbots analyze them using NLP techniques. These techniques involve tokenization, lemmatization, stemming, part-of-speech tagging, sentiment analysis, named entity recognition, etc. Thus, chatbots extract the meaning and intent of the user input and identify the relevant entities and parameters.
  • Response Generation: Once chatbots process inputs they use ML models of rules to generate appropriate responses based on them and the set goals. These responses can be text, image, audio, video, or a combination of them.
  • Output Delivery: As the response is generated chatbots send the response to users through the same interface or platform.

Natural language processing and machine learning are crucial to generate conversational and intelligent chatbots. NPL is a branch of artificial intelligence that deals with the interaction between computers to learn from data and experience without explicit programming.
