An explanation always relates to some context, with this context being defined by factors such as what is being explained, why the explanation is being given, who is the explainee (see Chap. 3 ), the modalities of explaining, the (un)observable facts about the situation, and so forth. In this chapter, we argue and explain why context cannot be reduced to components of a situation. Instead, context is also brought into, as well as brought about, that is, co-constructed in a situation between the partners when we consider interaction as the interface at which agents (human or artificial) negotiate their task, circumstances, relevant contextual factors, and so on. We propose four types of contexts for this interface. They vary in terms of gradual adaptability: A highly adaptive context is created by the interaction itself, building on the interaction’s progress both semantically and pragmatically. Future XAI developments can take the four types of contexts framework into account depending on what they are aiming toward.
