论文摘要
上下文：需求质量会对在开发过程中使用需求工件的有效性和效率产生重大影响。诸如“至少”，“全部”或“恰好”之类的量词是用于表达要求的常见语言结构。可以通过肯定的短语（至少“至少”）或负短语（“不小于”）来制定量词。问题：长期以来，假定定量的否定会对需求的可读性产生负面影响，但是，对这些主题的实证研究仍然很少。主要思想：在与51名参与者的基于Web的实验中，我们比较了否定和量化词对阅读工作，阅读错误率和需求的阅读难度方面的可读性的影响。结果：对于9个量词中的5个，我们的参与者在肯定的短语上的表现与负词组相比更好。仅对于一个量词，负词组更有效。贡献：这项研究重点是对语言在需求工程中的影响建立经验理解。此外，它还提供了有关如何用语要求的具体建议。
Context: Requirements quality can have a substantial impact on the effectiveness and efficiency of using requirements artifacts in a development process. Quantifiers such as "at least", "all", or "exactly" are common language constructs used to express requirements. Quantifiers can be formulated by affirmative phrases ("At least") or negative phrases ("Not less than"). Problem: It is long assumed that negation in quantification negatively affects the readability of requirements, however, empirical research on these topics remains sparse. Principal Idea: In a web-based experiment with 51 participants, we compare the impact of negations and quantifiers on readability in terms of reading effort, reading error rate and perceived reading difficulty of requirements. Results: For 5 out of 9 quantifiers, our participants performed better on the affirmative phrase compared to the negative phrase. Only for one quantifier, the negative phrase was more effective. Contribution: This research focuses on creating an empirical understanding of the effect of language in Requirements Engineering. It furthermore provides concrete advice on how to phrase requirements.
