title = "Automatic Identification of Learners{\textquoteright} Language Background based on their Writing in Czech",
abstract = "The goal of this study is to investigate whether learners{\textquoteright} written data in highly inflectional Czech can suggest a consistent set of clues for automatic identification of the learners{\textquoteright} L1 background. For our experiments, we use texts written by learners of Czech, which have been automatically and manually annotated for errors. We define two classes of learners: speakers of Indo-European languages and speakers of non-Indo-European languages. We use an SVM classifier to perform the binary classification. We show that non-content based features perform well on highly inflectional data. In particular, features reflecting errors in orthography are the most useful, yielding about 89% precision and the same recall. A detailed discussion of the best performing features is provided.",
