本文介绍了在PennBioIE语料库中常见的特定领域动词及其相关动词名物化的论元结构的交替数据。交替（英语：Alternation）是理论语言学中动词表面句法形式的变化，例如FSH中不同形式的刺激刺激卵泡发育，卵泡发育受FSH刺激。这些数据被用来评估生物医学文本挖掘系统的交替的影响，并测试适合的子语言模型，生物医学文本。我们在PennBioIE语料库中检查了1，872个最常见的领域特定动词或其零相关名词的标记，并标记它们是否存在三种变化。然后，我们注释了746个标记的名词化与这些动词的参数和计数有关的存在或不存在的参数和非缺席的参数的句法位置的交替。我们发现，动词和名词化的交替是相当普遍的。我们还发现了一个以前没有描述过的涉及形容词现在分词的变化。我们发现，即使在这个语义限制的领域，交替是相当普遍的，和交替涉及名词化是异常多样化。尽管如此，子语言模型适用于生物医学语言。我们还报告了以前未描述的交替涉及形容词现在分词。
This paper presents data on alternations in the argument structure of common domain-specific verbs and their associated verbal nominalizations in the PennBioIE corpus. Alternation is the term in theoretical linguistics for variations in the surface syntactic form of verbs, e.g. the different forms of stimulate in FSH stimulates follicular development and follicular development is stimulated by FSH. The data is used to assess the implications of alternations for biomedical text mining systems and to test the fit of the sublanguage model to biomedical texts. We examined 1,872 tokens of the ten most common domain-specific verbs or their zero-related nouns in the PennBioIE corpus and labelled them for the presence or absence of three alternations. We then annotated the arguments of 746 tokens of the nominalizations related to these verbs and counted alternations related to the presence or absence of arguments and to the syntactic position of non-absent arguments. We found that alternations are quite common both for verbs and for nominalizations. We also found a previously undescribed alternation involving an adjectival present participle. We found that even in this semantically restricted domain, alternations are quite common, and alternations involving nominalizations are exceptionally diverse. Nonetheless, the sublanguage model applies to biomedical language. We also report on a previously undescribed alternation involving an adjectival present participle.
