自由文本表单提供了灵活的特性，可以抓取表单用户想要分享的任何内容，从而获
得极其有用的数据。然而，这种灵活性也使数据更难于分析。这种情况下，通常组
织会采取两种不同的方法来进行自由文本分析，每种方法都有其优点和缺点：
•
有些组织责成第三方公司或初级员工阅读每条评论，并对其进行分类。这种方

付费给第三方来完成这项工作是很昂贵的。因此，很多组织已经完全取消了自
由文本条目，以便在分析中更容易评估用户的反应。通过将反馈限制在一组预
定义的选择中，消除了表单用户分享其宝贵见解的灵活性。
自由文本往往能填补差的或正处于发展中的系统的空白。由于系统的复杂性或改变
的成本太高，组织改变关键的业务系统时很吃力。自由文本使他们能够捕获和存储
使系统发挥作用所需的数据，但从数据分析的角度来看，自由文本也使数据难以进
行大规模的分析。

如何在
Tableau
中分析自由文本
尽管有其缺点，但自由文本是非常有价值的，不应该从表单和系统中消除。当系统
或表单的其他部分没有提供别的方式让用户充分分享他们的反馈时，自由文本可以
提供“全面”的回应。例如，撰写无偏见的调查是一项非常困难的任务，所以自由
文本框可以捕捉到其他方式无法收集的信息。这可能会促进产品创新，或者在没有
昂贵的客户访谈的情况下，让那些平常无法发现的服务差距凸显出来。
然而，由于以下原因，寻找这些自由文本的信息块可能具有挑战性：
