A Knowledge-Based Agent (KBA) is an AI system that makes decisions based on a structured knowledge base. It stores facts, rules, and experiences to reason and solve problems.

Key Components of a Knowledge-Based Agent:

1. Knowledge Base (KB) – Contains facts and rules about the world.

2. Inference Engine – Uses logic to derive new information from existing knowledge.

3. Perception & Action – Gathers inputs from the environment and makes decisions.

4. Learning Mechanism – Updates the knowledge base over time.

How It Works:

1. The agent perceives the environment.

2. It retrieves relevant knowledge from the KB.

3. The inference engine applies logical rules to deduce conclusions.

4. It takes action based on the derived information.

5. The KB updates based on new data.

Examples:

• Chatbots & Virtual Assistants (e.g., AI avatars with a knowledge base for FAQs)

• Medical Diagnosis Systems (e.g., AI recommending treatments based on medical knowledge)

• 

• Automated Customer Support (e.g., AI handling troubleshooting steps)

• Knowledge-Based Agents (KBAs) are highly relevant to AI-powered self-service kiosks, as they enable intelligent, interactive, and adaptive customer experiences.

  How Knowledge-Based Agents Work in Self-Service Kiosks

  1. Understanding User Input

     • Uses ASR (Automated Speech Recognition) and NLP (Natural Language Processing) to interpret voice or text inputs.

     • Example: A customer asks, "Where can I find vegan options?" → The KBA retrieves relevant data.

  2. Knowledge Retrieval & Decision Making

     • The knowledge base contains information on products, services, FAQs, and troubleshooting steps.

     • The inference engine applies rules to provide the best response.

     • Example: A hotel kiosk retrieves restaurant menus, location details, and booking options when a guest asks about dining.

  3. Personalized Responses & Recommendations

     • Uses a multi-dimensional affinity engine (like DaveAI) to offer tailored suggestions.

     • Example: In a shopping mall, a kiosk recommends electronics stores based on a user’s browsing history.

  4. Action Execution

     • The kiosk executes actions like booking a room, placing an order, or guiding users via interactive maps.

     • Example: A customer asks for a refund process → The kiosk walks them through the steps and prints a receipt.

  5. Continuous Learning & Adaptation

     • The learning mechanism updates based on interactions and feedback.

     • Example: If many users ask about Wi-Fi issues, the kiosk adapts by offering troubleshooting guides.
