Was ist Expert Systems

Definition

Expert systems are computer programs that emulate the specialized knowledge and problem-solving capabilities of a human expert within a narrowly defined domain. They operate on a structured knowledge base and an inference engine (reasoning mechanism) to make logical deductions.

Explanation

Within the historical context of Artificial Intelligence (symbolic AI), expert systems laid the groundwork for automated decision-making, which is now ubiquitous in modern B2B and SaaS software. While modern systems often rely on probabilistic Machine Learning, classic expert systems leverage deterministic "if-then" rules for diagnosis, configuration, or planning. In highly regulated industries such as tax consulting, legal services, or medical diagnostics, rule-based systems continue to be deployed because their decision paths, unlike those of Deep Learning models, are fully traceable and transparent. SaaS providers are increasingly combining these rigid rule systems with generative AI to merge the best of both worlds: the reliability of logical rules and the flexibility of modern language models.
