中文摘要
数据挖掘和数据分析已经成为企业和政府机构的标准做法。然而,分析结果只与输入数据一样好。遗憾的是,现代数据库和信息系统的规模和复杂性使其难以保证数据质量。特别是,对数据语义的不充分理解(导致糟糕的数据库设计)、数据随时间的演变(例如,由于集成新的数据源)以及容易出错的收集可能导致数据不一致、不正确和不完整。了解和监测数据质量,避免垃圾进垃圾出问题,是一个重要而具有挑战性的问题。
英文摘要
Data mining and data analysis have become standard practice in business and government organizations. However, analysis results are only as good as the input data. Unfortunately, the size and complexity of modern databases and information systems make it difficult to ensure data quality. In particular, inadequate understanding of the data semantics (leading to poor database design), data evolution over time (e.g., due to integrating new data sources) and error-prone collection may lead to data that are inconsistent, incorrect and incomplete. Understanding and monitoring data quality to avoid the "garbage-in-garbage-out" problem is an important and challenging issue.
