In many language learning scenarios, it is important to anticipate spelling errors. We model the spelling difficulty of words with new features that capture phonetic phenomena and are based on psycholinguistic findings. To train our model, we extract more than 140,000 spelling errors from three learner corpora covering English, German and Italian essays. The evaluation shows that our model pred...

We describe the NUS Corpus of Learner English (NUCLE), a large, fully annotated corpus of learner English that is freely available for research purposes. The goal of the corpus is to provide a large data resource for the development and evaluation of grammatical error correction systems. Although NUCLE has been available for almost two years, there has been no reference paper that describes the...

Investigating language acquisition by non-native learners helps to understand important linguistic issues and develop teaching methods, better suited both to the specific target language and to the learner. These tasks can now be based on empirical evidence from learner corpora. A learner corpus consists of language produced by language learners, typically learners of a second or foreign langua...

In the development of corpus linguistics, the creation of corpora has had a critical role in corpus-based studies. The majority of created corpora have been associated with English and native languages, while other languages and types of corpora have received relatively less attention. Because an increasing number of corpora have been constructed, and each corpus is constructed for a definite p...

Computer learner corpora have been widely used by SLA/EFL specialists since mid 1990s to gain better insights into authentic learner language. The work presented in this paper examines the inter-language of Taiwanese learners of English from a part-of-speech sequence perspective. Two pre-tagged corpora (one learner corpus and one native corpus) are involved in this work. The experimental result...

This study investigates the usefulness of the Treebank of Learner English (TLE) when applied to the task of Native Language Identification (NLI). The TLE is effectively a parallel corpus of Standard/Learner English, as there are two versions; one based on original learner essays, and the other an error-corrected version. We use the corpus to explore how useful a parser trained on ungrammatical ...
