This paper describes methods to recognize English utterances by Japanese learners as accurately as possible and detects grammatical errors from the transcription of the utterances. This method is a building block for the voice-interactive Computer-Assisted Language Learning (CALL) system that enables a learner to make conversation practice with a computer. A difficult point for development of s...

This paper describes an implemented on-line English grammar checker for students of English as a second language. This system focuses on a limited category of frequently occurring grammatical mistakes in essays written by students in the English Language Programs at the University of X. The grammar checker exploits the syntactic domain of locality from a Combina-tory Categorial Grammar for the ...

This study focused on the effect of transcribing task, as a noticing activity, on EFL learners’ grammatical accuracy. For 20 sessions, oral discussion tasks were assigned to 2 intermediate adult EFL classrooms, with 1 class serving as the control group and the other as the experimental group. For this purpose, the learners were divided into groups of 3 or 4 in each class. Learners in both group...

State-of-the-art systems for grammatical error correction are based on a collection of independently-trained models for specific errors. Such models ignore linguistic interactions at the sentence level and thus do poorly on mistakes that involve grammatical dependencies among several words. In this paper, we identify linguistic structures with interacting grammatical properties and propose to a...

s away from this intention. (The plural grammatical feature of mistakes is not represented.) Representations in which semantic roles reference event variables are called neoDavidsonian, since Davidson did not use semantic roles in his representations. The use of semantic roles has the disadvantage of being grammatical ill-defined. Whereas grammatical functions like subject and object are reason...

Typical grammar checking software use some form of natural language parsing to determine if errors exist in the text. If a sentence is found ungrammatical, the grammar checker usually seeks a single grammatical error as an explanation. For non-native speakers of English, it is possible that a given sentence contain multiple errors and grammar checkers may not adequately explain these mistakes. ...

Verb errors are some of the most common mistakes made by non-native writers of English but some of the least studied. The reason is that dealing with verb errors requires a new paradigm; essentially all research done on correcting grammatical errors assumes a closed set of triggers – e.g., correcting the use of prepositions or articles – but identifying mistakes in verbs necessitates identifyin...
