The purpose of this study is to analyze vocabulary found in "Donguibogam", one of the medical books in mid-Chosun, through Corpus-based analysis, one of the text analysis methods. According to it, Donguibogam has total 871,000 words in it, and Chinese characters used in it are total 5,130. Among them, 2,430 characters form 99% of the entire text. The most frequently appearing 20 Chinese characters are mainly function words, and with this, we can see that "Donguibogam" is a book equipped with complete forms of sentences just like other books. Examining the chapters of "Donguibogam" by comparison, Remedies and Acupuncture indicated lower frequencies of function words than Internal Medicine, External Medicine, and Miscellaneous Diseases. "Yixuerumen (Introduction to Medicine)" which influenced "Donguibogam" very much has lower frequencies of function words than "Donguibogam" in its most frequently appearing words. This may be because "Yixuerumen" maintains the form of Chileonjeolgu (a quatrain with seven Chinese characters in each line with seven-word lines) and adds footnotes below it. Corpus-based analysis helps us to see the words mainly used by measuring their frequencies in the book of medicine. Therefore, this researcher suggests that the results of this analysis can be used for education of Chinese characters at the college of Korean Medicine.

한국어 의미역 결정(Semantic Role Labeling)은 주로 기계학습에 의해 이루어지며 많은 말뭉치 자원을 필요로 한다. 그러나 한국어 의미역 결정 시스템에 사용되는 Korean PropBank는 의미역이 부착된 용언과 용언 격틀이 PropBank에 비해 각각 1/5, 1/2 수준에 불과하다. 따라서 본 논문에서는 한국어 의미역 결정 시스템을 위해 의미역이 부착된 용언과 용언 격틀을 확장하여 Korean PropBank를 확장 시키고자 한다. 대부분의 의미역 결정 시스템은 학습 도메인에 의존적이기 때문에 적용 도메인 변경에 따른 성능 하락이 나타날 수 있다. 본 논문에서는 기존의 학습 말뭉치와 적은 양의 새로운 학습 말뭉치를 활용하여 새로운 도메인에 대해 의미역 결정 시스템의 성능 하락을 최소화 할 수 있는 도메인 적응 기술을 Structural SVM(S-SVM)과 Deep Neural Network(DNN) 기반 한국어 의미역 결정 시스템에 적용하여 그 실효성을 알아보고자 한다.

The data accumulated in this database will be used to develop a speaker identification system. This may also be applied towards, but not limited to, fields of phonetic studies, sociolinguistics, and language pathology. We plan to supplement the large-scale speech corpus next year, in terms of research methodology and content, to better answer the needs of diverse fields. The purpose of this study is to develop a speech corpus for standard Korean speech. For the samples to viably represent the state of spoken Korean, demographic factors were considered to modulate a balanced spread of age, gender, and dialects. Nine separate regional dialects were categorized, and five age groups were established from individuals in their 20s to 60s. A speech-sample collection protocol was developed for the purpose of this study where each speaker performs five tasks: two reading tasks, two semi-spontaneous speech tasks, and one spontaneous speech task. This particular configuration of sample data collection accommodates gathering of rich and well-balanced speech-samples across various speech types, and is expected to improve the utility of the speech corpus developed in this study. Samples from 639 individuals were collected using the protocol. Speech samples were collected also from other sources, for a combined total of samples from 1,012 individuals.

This paper investigated the phonological processes of monophthongs and diphthongs in pronounced phrasal words of the Seoul Corpus by gender and age groups in order to provide linguists and phoneticians with a clearer understanding of the spoken Korean. Both orthographic and pronounced phrasal words were extracted from the transcribed label scripts of the Corpus using Praat. Then, phonological processes of monophthongs and diphthongs were tabulated using an R script after syllabifying the phrasal words into separate components. Results revealed that 97% of the number of syllables in the orthographic and pronounced phrasal words were the same while 65.8% showed difference in the syllable structure. 90.5% of the vowels in the orthographic phrasal words were realized in the pronounced phrasal words. A Chi-square test of independence was performed to obtain a significant dependence in the distribution of phonological process types of male and female groups along with a very strong correlation. Female group changed the diphthong yo into yv at the end of the pronounced phrasal words more often than the male group did. Age groups also showed a significant dependence in the distribution of phonological process types along with a very strong correlation. Females in the 40s produced the diphthong yv and made the vowel raising at the end of the pronounced phrasal words most often among the gender and age groups. From the results, this paper concludes that an analysis of phonological processes in light of syllable structure can contribute greatly to the understanding of the spoken Korean.

This paper is motivated by Watanabe's (2001) observation that English byphrase passives are sometimes translated into Japanese object topicalization constructions. That is, the original English sentence in the passive may be translated into the active voice with the logical object topicalized. A number of scholars, including Chomsky (1981) and Baker (1992), have remarked that languages have various ways to avoid focusing on the logical subject. The aim of the present study is to examine the translation equivalents of the English by-phrase passives in an English-Korean parallel corpus compiled by the author. A small sample of articles from Newsweek magazine and its published Korean translation reveals that there are indeed many ways to translate English by-phrase passives, including object topicalization (12.5%). Among the 64 translated sentences analyzed and classified, 12 (18.8%) examples were problematic in terms of agent defocusing, which is the primary function of passives. Of these 12 instances, five cases were identified where an alternative translation would be more suitable. The results suggest that the functional characteristics of English by-phrase passives should be highlighted in translator training as well as language teaching.

바꿔쓰기(paraphrasing)는 동일한 내용을 다르게 표현하는 방식을 의미한다. 이러한 바꿔쓰기표현들(paraphrues)은 기계번역, 질의 응답 시스템, 문서 요약과 같은 다양한 분야에 매우 유용하게 사용될 수 있다. 그러나 이와 같은 바꿔쓰기표현의 유용성에도 불구하고 바꿔쓰기표현을 자동으로 추출할 수 있는 방법이 매우 어렵다. 우선 바꿔쓰기표현을 자동으로 추출할 수 있는 데이터를 구하는 것부터가 어려운 문제이다. 본 연구에서는 여러 버전의 한글 성경 코퍼스로부터 바꿔쓰기표현을 자동으로 추출해 보고자 한다. 성경은 각 문장이 절과 구로 나누어져 있어 문장과 문장을 정렬시키는 것이 매우 용이하다. 정렬된 여러 버전의 성경 코퍼스로부터 자율학습(unsupervised learning)을 통해서 자동으로 바꿔쓰기표현을 추출한다. 이와 같은 방법은 어휘수준의 바꿔쓰기표현 뿐만 아니라 구문수준의 바꿔쓰기표현도 추출할 수 있음을 보여준다.

말뭉치를 이용하여 통계적으로 의미역 결정(semantic role labeling)을 하기 위해서는, 의미역을 태깅하는 작업이 필수적이다. 그러나 한국어의 경우 의미역이 태깅된 대량의 말뭉치를 구하기 힘들며, 이를 직접 구축하기 위해서는 많은 시간과 노력이 필요한 문제점이 있다. 본 논문에서는 비지도 학습의 하나인 self-training 알고리즘을 적용하여, 의미역이 태깅되지 않은 말뭉치로부터 의미역을 결정하는 방법을 제안한다. 이를 위해, 세종 용언 전자사전의 격틀 정보를 이용하여 자동으로 학습 말뭉치를 구축하였으며, 확률 모델을 적용하여 점진적으로 학습하였다. 그 결과, 4개의 부사격 조사에 대해 평균적으로 83.00%의 정확률을 보였다.

This paper investigates the phonological processes of consonants in pronounced words in the Seoul Corpus, and compares the frequency distribution of these processes to provide a clearer understanding of conversational Korean to linguists and teachers. To this end, both orthographic and pronounced words were extracted from the transcribed label scripts of the Seoul Corpus. Next, the phonological processes of consonants in the orthographic and pronounced forms were tabulated separately after syllabifying the onsets and codas, and major consonantal processes were examined. First, the results showed that the majority of the orthographic consonants' sounds were pronounced the same way as their pronounced forms. Second, more than three quarters of the onsets were pronounced as the same forms, while approximately half of the codas were pronounced as variants. Third, the majority of different onset and coda symbols were primarily caused by deletions and insertions. Finally, the five phonological process types accounted for only 12.4% of the total possible procedures. Based on these results, this paper concludes that an analysis of phonological processes in spontaneous speech corpora can improve the practical understanding of spoken Korean. Future studies ought to compare the current phonological process data with those of other languages to establish universal patterns in phonological processes.

본 논문에서는 띄어쓰기가 전혀 되어 있지 않은 문자열을 입력 받아 말뭉치에서 추출한 어절 정보를 이용하여 자동 띄어쓰기를 해 주는 방법론을 제안한다. 형태소 분석기도 사용되나 오류 수정이라는 제한적인 용도로만 사용된다. 성능 평가를 위해 1,000만 어절 규모의 세종 말뭉치에서 순수 한글 585만 어절을 발췌하여 10 개의 세트로 나누고 10 배수 교차 검증을 실시한 결과 98.06%의 음절 정확도와 94.15%의 어절 재현율을 얻었다. 또한, 개인용 컴퓨터에서 초당 25만 어절, 1.8 MB의 문서를 처리할 수 있을 정도로 빠르다. 제안된 방법의 정확도나 재현율은 어절 사전의 크기에 영향을 받기 때문에 보다 큰 말뭉치로 어절 사전을 구축하면 성능이 더욱 향상될 것으로 기대된다.
