Book excerpt: This volume illustrates new trends in corpus linguistics and shows how corpus approaches can be used to investigate new datasets and emerging areas in linguistics and related fields. It addresses innovative research questions, for example how prosodic analyses can increase the accuracy of syntactic segmentation, how tolerant English language teachers are about language variation, or how natural language can be translated into corpus query language. The thematic scope encompasses four types of ‘boundary crossings’. These include the incorporation of innovative scientific methods, specifically new statistical techniques, acoustic analysis and stylistic investigations. Additionally, temporal boundaries are crossed through the use of new methods and corpora to study diachronic data. New methodologies are also explored through the analysis of prosody, variety-specific approaches, and teacher attitudes. Finally, corpus users can cross boundaries by employing a more user-friendly corpus query language.
