Input Processing
When a user sends a message, the chatbot tokenizes the input—breaking it into words or phrases—normalizes the text (e.g., converting to lowercase), and removes stop words. This prepares the input for interpretation.Intent Recognition
The core AI component employs NLP algorithms to understand the user's intent or goal behind the message. For example, it recognizes whether the user wants to check an order status, get product information, or schedule an appointment. Advanced chatbots use large language models (LLMs) to grasp context, resolve ambiguities, and interpret complex queries Qualimero.Dialog Management
This module maintains conversation flow, considering context from previous exchanges. It determines the next action—whether to ask clarifying questions or proceed with fulfilling the user's request IBM.Response Generation
Based on dialog management decisions, the chatbot constructs a reply. It can use template-based responses, rule-based systems, or neural network models that generate natural language responses. Sometimes, it creates new content such as summaries, translations, or recommendations Chatfuel, Drift.- Enterprise AI chatbots like IBM Watson Assistant seamlessly integrate with existing systems (e.g., CRM platforms), automate routine inquiries, and learn from interactions to improve responses IBM.
