Cognitive Computing

A subset of AI that simulates human thought processes in a computerized model, aiming to solve complex problems without human assistance.

Definition

Encompasses systems (e.g., IBM Watson) that use NLP, machine learning, and reasoning to interpret unstructured data, learn over time, and provide evidence-based recommendations. Cognitive computing workloads require robust validation, transparent reasoning chains, and continuous updating to avoid drifting from real-world knowledge.

Real-World Example

A healthcare provider uses a cognitive computing platform that reads medical journals, patient records, and clinical guidelines to suggest personalized treatment plans—presenting supporting evidence citations so clinicians can verify each recommendation.
