Technical writers and translators struggle with language consistency in emerging technologies. Corpus linguistics can track language structures in such quickly developing environments. An ad-hoc corpus may be the tool needed for technical communicators. Key concepts: Mega-corpora versus ad-hoc corpora: The term “mega-corpora” typically covers the existing national corpora, whereas ad-hoc corpora can be created quickly for technical communication. Variation versus consistency: variation covers the range of possible solutions compared to the need for consistency of terminology in given contexts. Representativeness versus adequacy: representativeness defines the possibility of variation within the scope of the field; in contrast , adequacy represents contextual suitability. Key lessons: To use ad-hoc corpora as a tool for keeping track of and understanding language variation in texts about emerging technology: (1) design and compile a small set of relevant descriptions regarding the emerging technology, (2) use the software corpus tool representation of corpora to evaluate whether the ad-hoc corpus is representative-meaning that adding new texts does not add new words or variations in terminology use, (3) use the software corpus tool AntConc to analyze the ad-hoc corpus finding concordance patterns and variation in terminology usage, and (4) use linguistic strategies for selecting terminology based on linguistic evidence rather than intuition. Implications for practice: The ad-hoc corpus method offers an evidence-based approach for determining patterns of terminology. This method can be applied to standardizing product documentation or tracking variations in language use and can help technical writers and translators keep track of evolving terminology for emerging technologies.

This special issue examines theories and practices of professional communication outside the US. In this editorial, we preview each article of this issue and place those articles in the context of current practices and theories in the field. We also outline crucial questions and directions for future research. These directions include the call for a more comprehensive view of international professional communication, which takes into account philosophies, approaches, and practices which are current in Finland and China.

The Multimodal approach offers technical communicators and science writers an analytical tool to synthesize the meaning made in the connections across communicative modes. This multimodal synthesis can help technical communicators better exploit the meaning-making potential of multimodal combinations and understand the needs of future generations shaped by their increasingly developed multimodal literacy.
