图形和文本陈述过程模型的差异研究
Investigating Differences between Graphical and Textual Declarative Process Models
摘要：
业务流程建模的声明式方法被认为非常适合高度易变的环境，因为它们支持高度的灵活性。然而，在理解声明性流程模型方面的问题常常阻碍了它们的采用。特别是，一项研究表明，在图形级别上，命令式和声明式流程建模语言中存在的方面虽然具有不同的语义，但会造成相当大的麻烦。在这项工作中，我们调查是否一个符号，不包含图形外观，即，一个文本符号，可以帮助避免这个问题。尽管文本表征不存在相似性，但在我们的实证研究中，它在出错率、持续时间和脑力劳动方面表现得更差，因为文本表征迫使读者在心理上合并文本信息。同样，受试者自己表示图形表示更容易理解。
英文摘要：
Declarative approaches to business process modeling are regarded as well suited for highly volatile environments, as they enable a high degree of flexibility. However, problems in understanding declarative process models often impede their adoption. Particularly, a study revealed that aspects that are present in both imperative and declarative process modeling languages at a graphical level-while having different semantics-cause considerable troubles. In this work we investigate whether a notation that does not contain graphical lookalikes, i.e., a textual notation, can help to avoid this problem. Even though a textual representation does not suffer from lookalikes, in our empirical study it performed worse in terms of error rate, duration and mental effort, as the textual representation forces the reader to mentally merge the textual information. Likewise, subjects themselves expressed that the graphical representation is easier to understand.
