AI Bot Service

1. What is AI Bot Service?
AI Bot Service is a platform or framework that enables developers to create, deploy, and manage AI-powered chatbots and virtual assistants. These services typically provide Natural Language Processing (NLP), Machine Learning (ML), and automation capabilities to help bots understand user inputs, process requests, and generate intelligent responses.
2. How AI Bot Service works?
2.1. User input
The user sends a text or voice input via a chatbot interface on your website, your application,… E.g. “Where is my pizza order?”
2.2. Input processing
If the input is voice based, it is converted into text using a Speech-to-Text service. Preprocessing:
- Tokenization (splitting words).
- Ignoring common words.
- Cconverting words to their base forms.
2.3. Natural Language Understanding (NLU)
The bot service processes the text to:
- Identify intent: “Track Order”
- Extract entities:
- Food item: Pizza
- Order ID: not detected
- Bot recognizes missing info and responds: “Can you provide your order ID?”
- User replies: “My order ID is #12345”
- NLU detects order ID: #12345
2.4. Decision making
Calls the APIs system to check order status. E.g. From the order #12345, getting the response
- Status: “Out for delivery”
- Estimated time”: “30 minutes”
2.5. Response generation
The bot formats the response and sends it. E.g. “Your order #12345 is out for delivery and will arrive in 30 minutes”
2.6. User interaction & feedback loop
The response is delivered to the user. If the bot fails to answer, it may escalate to a human agent or ask for clarification. AI models can learn from user feedback to improve future responses.
