The BATMAT Corpus

The BATMAT Corpus

The BATMAT corpus (‘BA Theses MA Theses’) is a new addition to advanced EFL learner corpora. The compilation of the corpus was initiated in 2012 and directed until 2017 by Dr Signe-Anita Lindgrén, who served as H.W. Donner Lecturer in Applied Linguistics within the project “Advances in Applied Linguistics” (AAL, 2012-2017, a project directed by Professor Tuija Virtanen-Ulfhielm). The five-year AAL project was financed by the H.W. Donner Fund of the Åbo Akademi Foundation.

The BATMAT corpus comprises some 3 million words derived from 120 BA theses and MA theses written by predominantly L1 Finland-Swedish speakers studying English Language and Literature at Åbo Akademi University, Finland. The BA theses included in the corpus were completed between 2002 and 2016 while the MA theses originate from the period of 1972-2016. The corpus consists of theses from three topic areas: linguistics, literature, and society. The L1 of some of the students is Finnish, or occasionally another language; all are fluent speakers of Swedish. Written consent to include the thesis in the corpus was collected from the writers. Enquiries concerning the use of the corpus for research purposes should be addressed to Professor Brita Wårvik.

Student work based on another two learner English corpora:

Within the framework of the AAL project, Dr Signe-Anita Lindgrén also initiated and directed collections of learner English for studies of EFL lexical knowledge and reading fluency (LONGLEX) as well as spoken academic discourse (Talkabulary). These two corpora are no longer available for use. The following BA and MA theses use data from the two corpora.
