先前解释缺失(意外)查询结果的工作确定了查询或数据的哪些部分导致了错误结果,或者修复查询或数据以修复此类错误。生成修复的问题通常表示为优化问题,即返回最优wrt的单个修复。达到一些标准,比如最小化修复的副作用。然而,这样的优化目标可能无法具体地模拟用户(通常很难形式化)关于哪种修复是“正确的”的概念。在本文中,我们激励混合解释和修复,即同时修复查询和数据。而不是返回一个“最佳”修复,我们主张一种方法,授权用户探索可能的维修空间有效。我们还提出了一个概念验证的实施和概述开放的研究问题。
Prior work on explaining missing (unexpected) query results identifies which parts of the query or data are responsible for the erroneous result or repairs the query or data to fix such errors. The problem of generating repairs is typically expressed as an optimization problem, i.e., a single repair is returned that is optimal wrt. to some criterion such as minimizing the repair’s side effects. However, such an optimization objective may not concretely model a user’s (often hard to formalize) notion of which repair is “correct”. In this paper, we motivate hybrid explanations and repairs, i.e., that fix both the query and the data. Instead of returning one “optimal” repair, we argue for an approach that empowers the user to explore the space of possible repairs effectively. We also present a proof-of-concept implementation and outline open research problems.
