At its core, a contextual foundation refers to the information that provides relevant CONTEXT around data or inputs. In the case of AI, particularly in prompt engineering for LLMs, context often includes understanding previous prompts, integrating historical interactions, and grasping the subtleties of language. According to a study by Kary Främling, the concept of
Contextual Importance Utility (CIU) plays a significant role in explaining the output of AI models in more meaningful ways, enhancing the concept of
explainable AI (XAI) (source).
