This volume brings together contributions from the Klagenfurt Conference of Corpus-Based Applied Linguistics (CALK14), in order to extend corpus linguistic research in different areas of applied linguistics. The studies gathered here explore the opportunities that both spoken and written corpora offer for answering questions in different domains of applied linguistics such as second language learning, language testing, comparative linguistics, learner pragmatics and specialised discourses. At the same time, the contributions also give insight into possible limitations and further challenges of corpus-based research in these areas.
