The task of Grammatical Error Correction (GEC) has received remarkable attention with wide applications in Natural Language Processing (NLP) recent years. While one the key principles GEC is to keep correct parts unchanged and avoid over-correction, previous sequence-to-sequence (seq2seq) models generate results from scratch, which are not guaranteed follow original sentence structure may suffe...

PURPOSE This study investigated the level of grammatical accuracy in typically developing 3-year-olds and the types of errors they produce. METHOD Twenty-two 3-year-olds participated in a picture description task. The percentage of grammatical utterances was computed and error types were analyzed. RESULTS The mean level of grammatical accuracy in typical 3-year-olds was ∼71%, with a wide ra...

The demand for computer-assisted language learning systems that can provide corrective feedback on language learners’ speaking has increased. However, it is not a trivial task to detect grammatical errors in oral conversations because of the unavoidable errors of automatic speech recognition systems. To provide corrective feedback, a novel method to detect grammatical errors in speaking perform...

This paper presents research on building a model of grammatical error correction, for preposition errors in particular, in English text produced by language learners. Unlike most previous work which trains a statistical classifier exclusively on well-formed text written by native speakers, we train a classifier on a large-scale, error-tagged corpus of English essays, relying on contextual and g...

The present accent rating study investigates the interaction between accent strength and grammatical correctness on perceived accentedness. German native (L1) listeners rated German sentences produced by L1 and non-native (L2) speakers. Sentences either contained a grammatical error or were grammatically correct. Results showed that grammatical correctness affected the accent rating of sentence...

Errors are one of the enigmatic parts in the process of foreign language (L2) learning as they are extremely versatile at each and every stage of the language learning proficiency. The present study, therefore, was an attempt to reveal Iranian EFL learners’ grammatical errors in writing at two levels of proficiency, namely lower intermediate and advanced, and then to investigate whether there w...
