Which application is commonly associated with expert systems?

Expert systems are computer programs that mimic the decision-making abilities of a human expert. They utilize a knowledge base and an inference engine to solve specific problems or provide solutions in a particular domain. Technical and customer support systems are prime examples of expert systems because they offer diagnostic assistance and troubleshooting advice based on a set of rules or knowledge that has been programmed into them. This allows users to receive expert-level guidance for resolving issues related to products or services without the immediate need for human intervention.

In contrast, the other applications listed may not primarily rely on an expert system framework. Financial transaction processing typically involves transaction management and record-keeping, which does not require decision-making in the same manner as expert systems. Online shopping platforms focus more on e-commerce functionality and user experience, while social media networking centers around user interaction and content sharing rather than decision-making assistance. Therefore, the association of expert systems is most accurately reflected in technical and customer support systems, which leverage specialized knowledge to assist users effectively.
