This paper describes ongoing work on the correction of adverb errors committed by Korean learners studying English as a foreign language (EFL), using an automated English writing assessment system. Adverb errors are commonly found in learners 'writings, but handling those errors rarely draws an attention in natural language processing due to complicated characteristics of adverb. To correctly detect the errors, adverbs are classified according to their grammatical functions, meanings and positions within a sentence. Adverb errors are collected from learners' sentences, and classified into five categories adopting a traditional error analysis. The error classification in conjunction with the adverb categorization is implemented into a set of mal-rules which automatically identifies the errors. When an error is detected, the system corrects the error and suggests error specific feedback. The feedback includes the types of errors, a corrected string of the error and a brief description of the error. This attempt suggests how to improve adverb error correction method as well as to provide richer diagnostic feedback to the learners.

This study investigated the use of grammatical markers of Korean speaking children(from 3 to 8 years old) and adults. Participants had no problem of speech and language. In this paper we examined the usage of grammatical markers were increasing from 3 to 8 years old even though it was still increasing after 8 years old. Specifically, they used subjective marker and adverb marker at all ages in large. A few adjective marker were used at all age group including adults. But the frequency of objective marker is increasing from 3 to adults. The pattern of usage is getting similar to adult's. The present study was also designed to investigate the characteristics of children's errors of grammatical markers. Results showed that there were a little differences among the age-groups. The substitution errors were occurred most frequently in all age-groups.
