Expert system shells in artificial intelligence are a foundational part of Artificial Intelligence and a prime example of Artificial Cognitive Systems (ACS). While expert systems like DENDRAL (1960), DART (1991), and IBM’s Watson (2011) may be rare today, the techniques they introduced—such as knowledge representation are still widely used in modern AI. For instance, ROSS (2017), known as the first AI-powered attorney and built on IBM’s Watson, can understand language, make best, and support conclusions with references. At AI Upsurge, we believe that learning about expert systems and ACS is crucial, as these principles continue to influence the capabilities of today’s AI systems and for 2024 journal of this topic is here click on the link – Expert System Journal.
An expert system shell in artificial intelligence is a software tool that provides the essential components, like a knowledge base and engine, to help developers create expert systems quickly.

Benefits of Expert System Shells in Artificial Intelligence
Expert system shells offer four advantages that make them popular in AI development:
Time and Cost Savings
Expert system shells save time and reduce costs by providing ready-made components like the knowledge base and inference engine. This eliminates the need to code these complex features from scratch, allowing quicker development and deployment of expert systems.
User-Friendly Interface
Many expert system shells come with user-friendly interfaces, making it easier for developers and domain experts to add or modify knowledge without extensive coding skills. This accessibility makes it possible for a broader audience to work with AI applications.
Flexibility and Customization
Expert system shells allow developers to tailor the system to their specific needs. The knowledge base and inference rules can be customized for various industries, from healthcare to finance to education, providing flexibility in designing solutions.
Built-in Features
Expert system shells often come with built-in features such as knowledge acquisition tools, explanation facilities, and rule editors. These features simplify the development process, enhance functionality, and provide transparent results that can be explained to end users.
Common Features of Expert System Shells in AI
Most Expert system shells in artificial intelligence provide essential features that enable the creation and functionality of AI-driven solutions. Here are the six primary features you’ll find in expert system shells:
User Interface
The user interface (UI) enables interaction between users and the system. A well-designed UI allows developers and end users to input information, view results, and navigate the expert system easily.
Knowledge Base Editor
The knowledge base editor allows developers to add, edit, or update the system’s knowledge base. This is where domain-specific information and rules are stored, forming the foundation for decision-making in the expert system.
Inference Engine
The inference engine is the component that processes information in the knowledge base and applies rules to reach conclusions or make decisions. It acts as the “brain” of the expert system, interpreting data and drawing insights.
Explanation Facility
The explanation facility provides users with understandable explanations for the conclusions reached by the expert system. This transparency helps build trust in the system, especially in fields like healthcare, education and finance, where explanations are critical.
Knowledge Acquisition Tools
Knowledge acquisition tools simplify the process of adding new knowledge to the system. These tools make it easier for domain experts to transfer their expertise into the system, ensuring that it remains accurate and up-to-date.
Rule Builder
The rule builder enables developers to create and manage rules for decision-making. This feature makes it possible to define how the system should respond to different inputs and conditions, adding flexibility and control over the expert system’s behavior.
Examples of Expert System Shells
Here are some popular expert system shells widely used in AI development:
CLIPS (C Language Integrated Production System)
CLIPS is an open-source expert system shell written in C. It’s known for its versatility and efficiency, making it ideal for a variety of applications. CLIPS supports rule-based programming, object-oriented programming, and procedural programming, making it a flexible choice for developers.
