Essentially, an AI chatbot is a computer program that simulates human conversation. Here's a breakdown:
Core Function:
It's designed to interact with users through text or voice, aiming to provide responses that feel natural and human-like.
AI Enhancement:
What sets AI chatbots apart from traditional chatbots is their use of artificial intelligence, particularly:
Natural Language Processing (NLP) : This allows the chatbot to understand and interpret the nuances of human language.
Natural Language Understanding (NLU): This helps the chatbot to determine the intent of the user's input.
Machine Learning (ML) : This enables the chatbot to learn from interactions, improving its responses over time.
Large language models (LLMs) : these models allow the chatbot to generate very human like responses, and to understand complex inputs.
Key Capabilities :
Answering questions.
Providing information.
Performing tasks (e.g., scheduling appointments, processing orders).
Offering customer support.
Applications:
Customer service.
Virtual assistants.
Information retrieval.
E-commerce.
In essence, AI chatbots are evolving tools that are becoming increasingly sophisticated in their ability to engage in meaningful conversations.
