物联网数据质量评价方法

1范围

本文件描述了物联网应用场景下的数据质量评价方法。

本文件适用于指导物联网数据全生存周期的数据质量评价过程的建立和审查。

2规范性引用文件

本文件没有规范性引用文件。

3术语和定义

下列术语和定义适用于本文件。

3.1

数据质量dataquality

在指定条件下使用时，数据的特性满足明确的和隐含的要求的程度。

[来源：GB/T36344—2018，2.3]

3.2

数据集dataset

具有一定主题，可标识并可被计算机化处理的数据集合。

[来源：GB/T36344—2018，2.6]

3.3

数据生存周期datalifecycle

将原始数据转化为可用于行动的知识的过程。

3.4

质量评价过程qualityevaluationprocedure

用于应用和报告质量评价方法及结果的操作。

4评价框架

物联网应用场景下，数据质量评价是在评价保障基础上通过数据范围界定，对数据选取的准确性、

一致性、完整性、规范性、时效性和可访问性等指标进行数据质量检查，并对权重进行分析，计算评价

结果的过程。数据质量评价实施过程主要包括数据范围界定、数据质量检查、权重分析、评价结果计算

和评价保障等5个环节，如图1所示。
