Problem Solving Methods

Problem solving methods (PSMs) are also designed to support knowledge sharing and reuse.

While ontologies capture a shared terminology, problem solving methods define generic algorithms, which can be applied to different tasks and domains. Problem solving methods and ontologies provide the two essential technologies which enable the development of knowledge-based applications by reuse.
