Abstract From a theoretical point of view, most researchers agree that phraseological modifications are characterized by three key features: 1. occasionality, 2. intentional deviance from conventional use, and 3. context-boundedness. The present paper deals with the feature of occasionality and its operationalization in the context of text-based phraseological research. In text-based studies to date, occasionality has been identified with an absence of lexicographic codification. Phraseological structures and meanings registered in dictionaries have been regarded as conventional, uncodified structures and meanings, as occasional and, eventually, as modifications unless there is clear evidence of an unacceptable and incorrect use of the phraseme. In this paper, however, it is argued that a simple identification of lexicographic codification and conventionality on the one hand and non-codification and occasionality on the other does not permit an adequate distinction between conventional and occasional uses of phraseological units. Instead, in the approach proposed here, it is the relative frequency of the particular phraseological form in the DeReKo corpus (Deutsches Referenzkorpus) that is used as the distinctive criterion to decide upon its status as conventional or occasional.

摘要从理论上讲，大多数研究人员都认为，短语修饰具有三个关键特征：1.偶然性； 2.故意偏离常规用法；以及3.语境限制。本文探讨了偶然性的特点及其在基于文本的短语研究中的可操作性。迄今为止，在基于文本的研究中，偶然性已被确定为没有词典编纂。词典中记录的短语结构和含义被视为常规的，未编纂的结构和含义，偶尔并最终被视为修饰，除非有明确的证据表明不可接受和不正确地使用该短语。但是，在本文中 有人认为，一方面对词典编纂和惯用性进行简单的识别，另一方面对非编纂和惯用性进行简单的识别，并不能在措辞单元的常规使用和偶然使用之间进行适当的区分。取而代之的是，在这里提出的方法中，正是DeReKo语料库（Deutsches Referenzkorpus）中特定用语形式的相对频率被用作确定其常规或偶然状态的独特标准。
