Emerging categories in scientific explanations

Clear and effective explanations are essential for human understanding and knowledge dissemination. The scope of scientific research aiming to understand the essence of explanations has recently expanded from the social sciences to include the fields of machine learning and artificial intelligence. Important contributions from social sciences include [18, 17, 22, 13, 5, 11] with works that examine critical aspects such as causality (cause-and-effect relationships), contrast (distinctions between differing scenarios), relevance (applicability of explanations), and truth (accuracy and verifiability of explanations). However, machine learning and natural language processing focus more on operational definitions and on the importance of constructing datasets, as seen in studies by [21, 23, 6]. Since explanations for machine learning decisions must be both impactful and human-like [10, 3, 20, 12, 4], a major challenge lies in developing explanations that emphasize proximal aspects -- details that are immediately relevant, direct and related to the user -- over broad algorithmic processes [21].
