Essay: A crucial that has been mentioned is that information quality needs to be assessed within the context of its generation and use because the attributes of quality can vary depending on the context in which it is to be used(Knight & Burm, 2005)."What is of good quality in one situation might not be of much help in another situation (Mai, 2013, p.686)."Quality dimensions such as relevance and usefulness are thus difficult to measure reliably due to their subjectivity (Knight & Burm, 2005).In support of this point, Arazy & Kopak(2011), who did empirical research on rating information quality attributes, found that it was difficult to reach agreement on the assessment of quality dimensions. Arazy & Kopak came to the following conclusion (2011, p.98): "We conclude that IQ is an elusive construct that is hard to measure, and users' quality estimates are subjective, therefore making it difficult for multiple assessors to reach an agreement on a resource's quality."Similarly, Mai (2013) stated that information quality is a difficult concept to quantity effectively, even though significant research effort has gone into developing objective characteristics.

已经被提到一个至关重要的是，信息质量需要在它的上下文中被评估其生成和使用，因为质量的属性取决于使用的上下文(Knight & Burm, 2005)。“在一种情况中什么是优质的，可能在另一种情况里不会有多大帮助(Mai, 2013， p.686)。”由于他们的主体性，质量维度相关性和实用性等难以可靠地衡量(Knight & Burm，2005)。Arazy & Kopak(2011)支持这个观点，对评级信息质量属性的实证研究,发现很难达成一致的意见在评估质量维度方面。Arazy & Kopak得出以下结论(2011年，p.98)：“我们得出结论，智商是一个难以捉摸的构造，并且用户的质量估计是主观的，因此很难通过多个评估资源的质量达成协议。” 同样，Mai(2013)指出，信息质量是一个很难使大多数信息有效的概念，尽管重要的研究工作已经进入发展中的客观特征。
