The world of artificial intelligence (AI) is constantly evolving and growing, with new technologies and applications being developed all the time. One exciting area of AI is the concept of knowledge-based agents. But, what exactly is a knowledge-based agent in AI and how does it work?

In other word, a knowledge-based agent is a type of AI system that uses its own internal knowledge base to make decisions and solve problems. This knowledge base is a combination of information as well as rules that the agent has learned from previous experiences or has been programmed with by a human.

Key Benefits of Knowledge-Based AI

  • Versatile problem-solving capability:
    • With their vast stores of information and the ability to use that information to make decisions, knowledge-based agents can solve a wide range of problems.
  • Human-like reasoning:
    • These agents can reason and make decisions in a manner similar to human beings. Which makes them highly versatile and adaptable.
  • Ability to learn:
    • Knowledge-based agents can learn from experience, adding to their internal knowledge base over time and becoming more effective problem-solvers.
  • Cost-effective:
    • Compared to other AI systems, knowledge-based agents are relatively simple and cost-effective to develop and implement.

What is the difference between rule-based and knowledge-based AI?

When it comes to AI systems, there are two main types:

  • Rule-based systems and
  • Knowledge-based systems.

So, what is the difference between the two?

A rule-based system uses a set of predetermined rules to make decisions and solve problems. These rules are fixed and cannot be changed, which means that the system is limited in its ability to adapt to new situations.

On the other hand, a knowledge-based system has the ability to learn and adapt, using its internal knowledge base to make decisions and solve problems. The constant updating of this internal knowledge base with new information and experiences makes the system much more flexible and adaptable than rule-based systems.

Applications of Knowledge-Based AI

  • Healthcare:
    • Doctors can use knowledge-based agents in the healthcare industry to assist in diagnosing diseases and making treatment recommendations.
  • Finance:
    • In finance, one can use knowledge-based agents to analyze market data and give investment advice.
  • Customer service:
    • In customer service, knowledge-based agents can be used to provide quick and accurate answers to customer questions, helping to improve the customer experience.
  • Education:
    • In education, knowledge-based agents can be used to provide personalized learning experiences, helping students to learn at their own pace and on their own terms.

Building a Knowledge-Based AI System

To build a knowledge-based AI system, you need to start by gathering information. This information can come from a variety of sources, including books, articles, and other AI systems.

Further, you need to organize this information into a structure that the AI system can understand. This structure is known as a knowledge base, and it consists of a series of rules and facts.

Finally, you need to build the AI system itself. This involves programming the system with the knowledge base, as well as developing algorithms. This will allow the system to use that knowledge to make decisions and solve problems.


In conclusion, knowledge-based AI is a powerful and versatile type of AI system that has the ability to make decisions and solve problems based on its internal knowledge base.

With its ability to learn and adapt, as well as its cost-effectiveness, knowledge-based Artificial Intelligence is a valuable tool for a wide range of industries and applications.
