知识发现对于成功的数据分析至关重要。我们提出了一种新型的元知识类型,即模式函数依赖性(PFD),该依赖性(PFD)结合了模式(或类似正则式规则)和完整性约束(ICS),以模拟部分值(或模式)之间的依赖关系(或元知识) )跨表中的不同属性。 PFD超出了经典的功能依赖性及其扩展。例如,在员工表中,ID“ F-9-107'” F'确定财务部门。此外,PFD的关键应用是使用它们来识别错误的数据。违反某些PFD的元组。在此演示中,与会者将体验以下功能:(i)PFD Discovery-自动从不同域中的(脏)数据发现PFD; (ii)使用PFD检测错误 - 我们将显示由PFD检测到但无法通过现有方法捕获的错误。
Knowledge discovery is critical to successful data analytics. We propose a new type of meta-knowledge, namely pattern functional dependencies (PFDs), that combine patterns (or regex-like rules) and integrity constraints (ICs) to model the dependencies (or meta-knowledge) between partial values (or patterns) across different attributes in a table. PFDs go beyond the classical functional dependencies and their extensions. For instance, in an employee table, ID "F-9-107', "F' determines the finance department. Moreover, a key application of PFDs is to use them to identify erroneous data; tuples that violate some PFDs. In this demonstration, attendees will experience the following features: (i) PFD discovery -- automatically discover PFDs from (dirty) data in different domains; and (ii) Error detection with PFDs -- we will show errors that are detected by PFDs but cannot be captured by existing approaches.
