ELLE - Estonian Language Learning and Analysis Environment.

Text corpora provide authentic material for language instruction and an insight into the development of learner language use. This pedagogical potential can be enhanced by accompanying user-friendly text analysis tools designed for researchers, teachers, and learners alike. We introduce the Estonian Language Learning and Analysis Environment (ELLE) that combines a growing corpus of Estonian learner writings (Estonian Interlanguage Corpus - EIC) with various applications for linguistic analysis and automated text evaluation. The toolkit can be employed to analyse EIC and other corpora as well as study materials or users' own texts. ELLE's ongoing implementation follows a prototype which was created using interaction and participatory design methods, involving members of different target groups. The paper outlines the system architecture and presents the functionalities of each tool, highlighting their unique features compared to alternative web applications. [ABSTRACT FROM AUTHOR]
