최근 대량의 텍스트 분석을 위해 딥 러닝(Deep Learning)을 활용하는 연구들이 활발히 수행되고 있으며, 특히 대량의 텍스트에 대한 학습 결과를 특정 도메인 텍스트의 분석에 적용하는 사전 학습 언어 모델(Pre-trained Language Model)이 주목받고 있다. 다양한 사전 학습 언어 모델 중 BERT(Bidirectional Encoder Representations from Transformers) 기반 모델이 가장 널리 활용되고 있으며, 최근에는 BERT의 MLM(Masked Language Model)을 활용한 추가 사전 학습(Further Pre-training)을 통해 분석 성능을 향상시키기 위한 방안이 모색되고 있다. 하지만 전통적인 MLM 방식은 신조어와 같이 새로운 단어가 포함된 문장의 의미를 충분히 명확하게 파악하기 어렵다는 한계를 갖는다. 이에 본 연구에서는 기존의 MLM을 보완하여 신조어에 대해서만 집중적으로 마스킹을 수행하는 신조어 표적 마스킹(NTM: Newly Coined Words Target Masking)을 새롭게 제안한다. 제안 방법론을 적용하여 포털 'N'사의 영화 리뷰 약 70만 건을 분석한 결과, 제안하는 신조어 표적 마스킹이 기존의 무작위 마스킹에 비해 감성 분석의 정확도 측면에서 우수한 성능을 보였다.

The purpose of this paper is to suggest a model for an English learning web-site using Korean folktales to stimulate the interest of beginners learning English, (elementary and early middle school ages) and suggest an integrated way of teaching 4 skills. The study first reviews the theoretical and historical backgrounds of storytelling using Korean folk tale, WBI (Web Based Learning), and learner-centered learning. Storytelling using Korean folk tale is an interactive way of teaching English through the use of words and actions from Korean traditional culture. The students can take pride in their own culture while learning a foreign language since they are familiar with the stories and the culture. Nowadays multicultural education is one of the big features of global education. Therefore there are benefits of studying English through Korean folktales. The websites can help students learn English ubiquitously with a learner-centered focus. For the study, we analyzed several digital English storytelling websites. The paper concludes that digital English story books need to improve their interactive ways of teaching for more effective learning. The authors created an integrated English learning website model using Korean folktales for beginners. We hope to introduce this type of learning through the website for higher level students in middle school. Further study should be conducted in order to make the websites more meaningful and useful for Korean students learning English.

This presents the preliminary results from work in progress of a paired study of the acquisition of voiceless stops by Spanish speakers learning English, and American English speakers learning Spanish. For this study the hypothesis was that the American speakers would have no difficulty suppressing the aspiration in Spanish unaspirated stops; the Spanish speakers would have difficulty acquiring the aspiration necessary for English voiceless stops, according to Eckman's Markedness Differential Hypothesis. The null hypothesis was proved. All subjects were given the same set of disyllabic real words of English and Spanish in carrier phrases. The tokens analyzed in this report are limited to word-initial voiceless stops, followed by a low back vowel in stressed syllables. Tokens were randomized and then arranged in a list with the words appearing three separate times. Aspiration was measured from the burst to the onset of voicing(VOT). Both the first language (Ll) tokens and second language (L2) tokens were compared for each speaker and between the two groups of language speakers. Results indicate that the Spanish speakers, as a group, were able to reach the accepted target language VOT of English, but English speakers were not able to reach the accepted range for Spanish, in spite of statistically significant changes of p<.OOl by speakers in both groups of learners. A closer analysis of the speech samples revealed wide variability within the speech of native speakers of English. Not only is variability in English due to the wide range of VOT (120 msecs. for English labials, for example) but individual speakers showed different patterns. These results are revealing for the demands requied in experimental designs and the number of speakers and tokens requied for an adequate description of different languages. In addition, a simple report of means will not distinguish the speakers and the respective language learning situation; measurements must also include the RANGE of acceptability of VOT for phonetic segments. This has immediate consequences for the learning and teaching of foreign languages involving aspirated stops. In addition, the labelling of spoken language in speech technology is shown to be inadequate without a fuller mathematical description.

The current study investigated whether Korean learners' English-learning environments, especially target English accent (General American English (GAE) vs. Southern British English (SBE)) and English-language experience affected their production of English vowels. Thirty six EFL learners, 27 ESL-US learners, and 33 ESL-UK learners produced 8 English vowels with a bVt frame (beat, bit, bet, bat, bought, bot, boat, boot). The learners' productions were acoustically analyzed in terms of F1 and F2 frequencies. The overall results revealed that the learners' target accent had an effect on their production of some English vowels. The EFL and ESL-US learners' (especially, female learners') production of bought, bot, boat, and boot, which show characteristic differences between the GAE and SBE accents, was closer to that of the native American English (AE) speakers than the native British English (BE) speakers. In contrast, the ESL-UK learners' production of bought and bot demonstrated the opposite pattern. Thus, the impact of target accent was not demonstrated across the board. The effect of the learners' different English-language experience was also rather limited. This was because the EFL learners' production was not much different from the ESL-US learners' production, in spite of the ESL-US learners' residence in the US for more than 9 years. Furthermore, the Korean learners, irrespective of their different English-language experience, tended to produce bit and bat with lower F1 than the native AE and BE speakers, thus resulting in bit and bat to be produced similarly to beat and bet, respectively. This demonstrates the learners' persistent L1 effects on their English vowel production despite the learners' residence in the English speaking countries or their high English proficiency.

There are various typing practice applications. In addition, research cases on learning applications that support typing practice have been reported. These services are usually provided in a way that utilizes their own built-in text. Learners collect various contents through web services and use them a lot for learning. Therefore, this paper proposes a learning application to increase the learning effect by collecting vast amounts of web content and applying it to typing practice. The proposed application is implemented using Tkinter, a GUI module of Python. BeautifulSoup module of Python is used to extract information from the web. In order to process the extracted data, the NLTK module, which is an English data preprocessor, and the KoNLPy module, which is a Korean language processing module, are used. The operation of the proposed function is verified in the implementation and experimental results.
