  • The problem of the sentence-based pronunciation evaluation task is defined in the context of subjective criteria. Three subjective criteria (that is, the minimum subjective word score, the mean subjective word score, and first impression) are proposed and modeled with the combination of word-based assessment. Then, the subjective criteria are approximated with objective sentence pronunciation scores obtained with the combination of word-based metrics. No a priori studies of common mistakes are required, and class-based language models are used to incorporate incorrect and correct pronunciations. Incorrect pronunciations are automatically incorporated by making use of a competitive lexicon and the phonetic rules of students' mother and target languages. This procedure is applicable to any second language learning context, and subjective-objective sentence score correlations greater than or equal to 0.5 can be achieved when the proposed sentence-based pronunciation criteria are approximated with combinations of word-based scores. Finally, the subjective-objective sentence score correlations reported here are very comparable with those published elsewhere resulting from methods that require a priori studies of pronunciation errors.

  • 주관적 문장이란 주관적인 내용을 포함한 문장으로써 저자의 제품이나 사건에 대한 생각을 알 수 있다. 주관적 내용임을 나타내는 주관적인 표현은 문장 전반적으로 골고루 나타날 수도 있지만 일부 한정된 영역에서만 발견될 수도 있다. 따라서 보다 정확한 분류를 위해서는, 문장 전체를 고려하는 정보 외에 사실이나 감정을 표현하는 주관적 혹은 객관적 표현구 정보의 활용이 필요하다. 본 연구에서는 문장 전체를 이용한 분류 결과와 감정 표현구를 이용한 분류 결과를 결합하여 주/객관적 문장 분류기의 성능을 향상시키는 방법을 제안한다. 한 문장은 여러 개의 표현구를 가질 수 있어 복수개의 표현구 단위 결과를 얻게 되며 기계 학습을 응용하여 문장 단위 결과와 결합한다. 실험을 통한 결과, 표현구 단위 결과물 중 최대값을 가지는 두 가지 결과와 문장 전체를 이용한 결과를 합침으로써 2.5% 성능 향상된 79.7%의 정확률을 얻을 수 있었다.

  • 이 연구는 2년차 신임 교사의 사례 연구를 통해 수학수업에 대한 신임교사의 발문 유형의 특성을 분석하고 그에 따른 대안을 탐색하기 위한 것이다. 연구 결과, 확인을 위한 발문이 가장 많았으며(69%), 이해를 위한 발문(25%), 성찰을 위한 발문(6%) 순이었고, 창의성 신장을 위한 발문은 하지 않는 것을 알 수 있었다. 더불어 기존 연구를 바탕으로 신임교사의 발문과 관련된 대안적인 창의성 신장을 위한 발문을 제안해 보았다.

  • In this paper, we presented the prosody analysis results of five selected words according to its usage in a sentence, i.e.. the part of sentence (PoS) while changing the type of sentences such as simple, conjugate, and complex sentences. The selected five Korean words were 'U-Ri-Na-Ra' 'Bul-Kuk-Sa', 'Uh-Muh-Ni', 'Han-Ra-San', and 'Cang-A-Ji'. These five words were used as a subjective, an objective, and an adverb in each simple, conjugate, and complex sentence. The pitch, energy, and duration of each word were then analyzed and used for the synthetic speech prosody Improvement. The subjective test on the prosody improvement showed that more than $50\%$ of our listeners are affirmative to the prosody Improvement of the synthetic speech.

  • The anchoring effect can be found when a decision shows cognitive prejudice towards the initial information given. Several studies have argued that such an effect is present even for judges in the courtroom. This paper seeks to find a relationship between judges' decisions on penalty sentences and the sentences recommended by prosecutors. In this study, 2,773 actual court cases are considered in the analysis, and quantile regression is used to show that the sentencing decisions judges make are anchored by the recommendations of prosecutors. However, this reliance on recommendations differs according to the seriousness of the crime committed. Specifically, at the lowest penalty levels, a one-month increase in the prosecutors' sentencing recommendation results in a 0.25-month increase in the judges' sentence, while at the highest sentence level, the judges' sentences increase by 0.78 months under an identical condition. The results of this research indicate the need to create more objective and clear sentencing guidelines in the future in an effort to mitigate the psychological pressure experienced by judges with regard to serious offences or heinous crimes.

  • The purpose of this study was to evaluate the maximum and optimal listening speed of Korean TTS for the blind. Five blind participants took part in this study. The instruments used in this study were 17 sentence sets (2 sets for an excercise, 10 sets for a repeated test, and 5 sets for a random test), with short meaningful sentences (the same sentences for the repeated test, different sentences for the random test) with 15 differentiated speeds (Range=0.8-3.6, SD=0.2). Each participant's maximum and quickest listening speeds were calculated by objective recall accuracy (determined by the number of correctly recalled syllables/the total number of syllables in a sentence X 100) and subjective recall accuracy (recall accuracy judged by each participant's subjective evaluation). The results showed that the participants' recall accuracy had a tendency to increase as the TTS speed decreased. Participants' subjective recall accuracy was higher than objective recall accuracy in the repeated tests and vice versa in the random tests. The results also revealed that the participants' sentence familiarity had an influence on their Korean TTS listening speed.

  • 서술형 문항은 수준 높은 사고능력 평가에 적합하나 채점이 쉽지 않다. 동일한 채점기준을 적용하더라도 채점자마다 서로 다른 채점을 할 수 있으므로 객관적인 채점 시스템이 필요하다. 그렇지만 채점 시스템을 구축하기 위해서는 표현 언어인 한국어 분석이 전제되어야 한다. 특히 서술형 문항의 답변은 단문형태가 아닌 복문이 내포된 복합 문장으로 표현되기 때문에 복합문의 한국어 분석이 이루어져야 한다. 본 연구는 이와 같은 서술형 문항의 자동 채점을 위해 한국어의 복합문을 구문의미 분석하는 시스템을 개발하고 시스템의 성능을 분석하였다. 이 시스템은 의미속성 사전을 활용하여 대상 구문의 의미적 제한조건을 검사하고 적합한 피수식 대상을 선별하여 구문의미분석을 실행한다. 실험 데이터에 대해 93%의 정확률을 얻어 제안한 시스템이 효과있음을 알 수 있었다. 본 연구의 시스템은 서술형 문항 채점에 활용할 수 있고 한국어 처리의 응용영역에 활용할 수 있을 것으로 기대된다.

  • This study is aimed to investigate the aspect of using relative clauses in Korean. The data used for this study were extracted from the Korean text books for the foreign students and from the Chinese students' Korean compositions. They are the learners of Korean language at the early intermediated stage. As the result of analyzing them, the followings were found I)the majority of relative clauses in Korean consists of left-branching sentences. ii)The number of the subject relative clauses was higher than object ones in both of them. Especially in the aspect of using relative clauses, subject ones were used even more frequently than objective ones. This result is corresponded to the previous thesis, "the subject relative clauses was acquired earlier than object ones". iii)The relative clauses that those with a head noun function as subject in the main sentence showed in higher proportion in comparison of those as object. That is, this study showed that subjects were used more frequently than objects in the relative clauses used in their compositions. Finally, this study analyzed the errors of adnominal ending usage occurring in their compositions. More errors occurred when adjective form ended with '-hada' are changed into adnominal ending one.
