摘要:

随着人工智能领域的最新进展,越来越多的决策任务被委托给软件系统。成功和采用此类系统的关键要求是用户必须信任系统选择,甚至完全自动化的决策。为了实现这一点,解释设施已被广泛调查,作为一种手段,建立信任这些系统,因为早期的专家系统。随着当今日益复杂的机器学习算法,在解释、问责制和对此类系统的信任方面的新挑战不断出现。在这项工作中,我们系统地回顾了文献中的建议给出系统的解释。这是一个包括推荐系统的系统家族,推荐系统是实践中最成功的一类建议软件。我们调查解释的目的,以及它们是如何产生的,呈现给用户,并评估。因此,我们得出一个新的全面分类的方面时,要考虑到当前和未来的决策支持系统设计的解释设施。分类法包括各种不同的方面,如解释目标,响应性,内容和呈现。此外,我们确定了一些迄今为止尚未解决的挑战,例如与解释的呈现以及如何评估解释设施相关的细粒度问题。

英文摘要:

With the recent advances in the field of artificial intelligence, an increasing number of decision-making tasks are delegated to software systems. A key requirement for the success and adoption of such systems is that users must trust system choices or even fully automated decisions. To achieve this, explanation facilities have been widely investigated as a means of establishing trust in these systems since the early years of expert systems. With today's increasingly sophisticated machine learning algorithms, new challenges in the context of explanations, accountability, and trust towards such systems constantly arise. In this work, we systematically review the literature on explanations in advice-giving systems. This is a family of systems that includes recommender systems, which is one of the most successful classes of advice-giving software in practice. We investigate the purposes of explanations as well as how they are generated, presented to users, and evaluated. As a result, we derive a novel comprehensive taxonomy of aspects to be considered when designing explanation facilities for current and future decision support systems. The taxonomy includes a variety of different facets, such as explanation objective, responsiveness, content and presentation. Moreover, we identified several challenges that remain unaddressed so far, for example related to fine-grained issues associated with the presentation of explanations and how explanation facilities are evaluated.
