외국어를 학습하는 데 있어서 해당 외국어의 의사소통 능력을 향상시키고 평가한다는 것은 상당히 큰 중요성을 가진다. 교실에서 학습자의 듣기, 말하기, 읽기, 쓰기 능력을 통해 학습자의 언어 능력을 함양하고 평가하기 위해 어떠한 연습문제나 시험 혹은 평가방법을 사용하느냐 하는 것은 학습자의 학습동기에 지대한 영향을 미친다. 왜냐하면, 보통 학습자들은 교수자가 무엇을 가르치고 기대하며 평가하느냐에 따라 자신들의 학습방법을 맞춰 나가기 때문이다. 이러한 맥락에서 본 연구는 보다 적극적인 학습자들의 참여를 유도하고 유연성 있는 학습자 중심의 학습법을 고양시키며 다양한 언어능력을 고취시키기 위하여, 효과적인 외국어 학습법의 하나로 알려진 paraphrasing을 학습에 활용하고자 한다. 특히 paraphrasing은 일상생활 속에서도 의사소통을 원활히 하기 위한 수단으로서 글 바꿔 쓰기 혹은 말 바꿔 말하기로 활용되기도 하나, 본 소논문에서는 paraphrasing이 학습을 목적으로 하는 학습현장에서 활용되었다는 것을 감안하여 의역을 통한 학습 혹은 의역학습법을 소개하고자 한다. 실제로 paraphrasing은 언어 및 외국어 학습자들에게 상당히 효과가 있는 것으로 알려진 것에 비해 실제로 한국어 교육현장에서 사용한 연구들은 거의 찾아 볼 수가 없다고 해도 과언이 아니다. 따라서, 의역학습법을 학습현장에서 도입했을 때 경험한 여러 시행착오를 바탕으로 실질적으로 교실에서 사용된 예시들을 소개하고, 한국어를 가르치는 교수자들과 한국어를 배우는 외국인 학습자들에게 paraphrasing을 사용한 새로운 한국어 교수방법과 평가 도구를 제안하고자 한다. 이를 통해, paraphrasing이 한국어를 가르치는 교수자들과 한국어를 배우고자 하는 외국 학습자들에게 효과적인 언어학습 도구로서 실질적으로 교육현장에서 널리 사용될 수 있는 계기가 되었으면 한다.

This research aims to evaluate the effects and the shortcomings of strategies for teaching paraphrasing to foreign university students. For this study, the effects of teaching paraphrasing skills on student's academic writing was investigated through the assessment of pre- and post-test writing tasks and through a focus group interview. The teaching of paraphrasing was divided into 3 instructional sessions and the focus group interview was conducted at the end of the last session. After each instructional session three trained assessors evaluated the outcomes of pre and post task writings; the in-depth focus group interviews were conducted on seven of the students in order to define better positive effects as well as shortcomings. By comparing the scores of pre- and post-task assignments it is possible to affirm that there is a meaningful difference for overall scores; moreover, in an analysis conducted on each single sub-element of the paraphrasing skill, it emerged that except for "task completion", all other four elements of "structure", "understanding core content", "change of expression" and "academic expressions" showed a statistically significant improvement in performance. On the other hand, as a result of the focus group interview, it was possible to individuate as main shortcomings insufficient vocabulary knowledge, poor overall comprehension of the reference material, lack of practice and difficulty in connect sentences organically. It is possible to consider these elements as limiting factors in understanding the reference material and making correct citations by the students. Therefore, we suggest as supplementary instructional strategies a deeper attention to the difficulty level of the text, the introduction of devices to understand better the content of the reference material and an integrated practice of the paraphrasing skill.

Pre-retrieval query formulation is an important step for identifying local text reuse. Local reuse with high obfuscation, paraphrasing, and translation poses a challenge of finding the reused text in a document. In this paper, three pre-retrieval query formulation strategies for heuristic retrieval in case of low obfuscated, high obfuscated, and translated text are studied. The strategies used are (a) Query formulation using proper nouns; (b) Query formulation using unique words (Hapax); and (c) Query formulation using most frequent words. Whereas in case of low and high obfuscation and simulated paraphrasing, keywords with Hapax proved to be slightly more efficient, initial results indicate that the simple strategy of query formulation using proper nouns gives promising results and may prove better in reducing the size of the corpus for post processing, for identifying local text reuse in case of obfuscated and translated text reuse.

This study examines the effects of Korean college students' English proficiency and the English text types on their paraphrases. Korean college students with three groups of English proficiency (high, mid, and low) read two types of English texts, causal texts, and argumentative texts, and paraphrased them in English. Students' paraphrase text was evaluated in terms of content (idea exposition, idea development, and wrap up), organization (coherence and cohesion) and language use (grammatical accuracy), and analyzed by MANOVA. As a result, it was found that there was a significant difference in their paraphrase performance according to the participants' English proficiency levels rather than the types of English texts. The results of this study have educational implications for English paraphrase education to prevent plagiarism for Korean university students.

In this paper, we present a pilot system that can extract paraphrases from a parallel corpus using to-training method. Paraphrases are useful for the applications that should rreate a varied ind fluent text, such as machine translation, question-answering system, and multidocument summarization system. One of the difficulties in extracting paraphrases is to find a rich source from which we can extract paraphrases. The bible is one of the good sources fur extracting paraphrases as it has several Korean versions in which every sentence can be easily aligned by the chapter and the verse. We ran extract not only the lexical-level paraphrases but also the phrasal-level paraphrases from the parallel corpus which consists of the bibles using co-training method.

This letter introduces a new method to automatically acquire paraphrases using bilingual corpora. It utilizes the bilingual dependency relations obtained by projecting a monolingual dependency parse onto the other language's sentence based on statistical alignment techniques. Since the proposed paraphrasing method can clearly disambiguate the sense of the original phrases using the bilingual context of dependency relations, it would be possible to obtain interchangeable paraphrases under a given context. Through experiments with parallel corpora of Korean and English language pairs, we demonstrate that our method effectively extracts paraphrases with high precision, achieving success rates of 94.3% and 84.6%, respectively, for Korean and English.

This research has been carried out to give economical incentives and to promote for the eco-friendly village. A standard model plan for the Korean eco-village has been prepared by systematically applying the results of the research to Boksoo village, which served as an exemplary model. Plans for promoting the Korean eco-village are finally derived after a series of theoretical assessment of conceptual propositions in harnessing natural elements well suited with man-made structures. The eco-friendly village that this study is to develop harnesses natural energy resources and establishes pleasant living environment for human. It minimizes the unjust load against nature and restrains the excessive consumption of irreplaceable indigenous energy and other natural resources on earth. Paraphrasing, the utilization of natural energy resources in the eco-friendly village features various schemes of the related technologies in energy conservation and exploitation of renewable energies including solar thermal, photovoltaic, daylighting, wind power and etc. The eco-friendly village would definitely make our world more healthier than before by suppressing the emission of green house gases from fossil fuels and ever increasing energy consumption.

Recently, the problem of plagiarism has emerged as a big social issue because not only literature but also thesis become the target of plagiarism. Even the government requires conformation for plagiarism of high-ranking official's thesis as a standard of their ethical morality. Plagiarism is not just direct copy but also paraphrasing, rewording, adapting parts, missing references or wrong citations. This makes the problem more difficult to handle adequately. We propose a plagiarism detection scheme called a bit signature in which each unique word of document is represented by 0 or 1. The bit signature scheme can find the similar documents by comparing their absolute and relative bit signatures. Experiments show that a bit signature scheme produces better performance for document copy detection than existing similar schemes.

Abstractive text summarization is a process of making a summary of a given text by paraphrasing the facts of the text while keeping the meaning intact. The manmade summary generation process is laborious and time-consuming. We present here a summary generation model that is based on multilayered attentional peephole convolutional long short-term memory (MAPCoL; LSTM) in order to extract abstractive summaries of large text in an automated manner. We added the concept of attention in a peephole convolutional LSTM to improve the overall quality of a summary by giving weights to important parts of the source text during training. We evaluated the performance with regard to semantic coherence of our MAPCoL model over a popular dataset named CNN/Daily Mail, and found that MAPCoL outperformed other traditional LSTM-based models. We found improvements in the performance of MAPCoL in different internal settings when compared to state-of-the-art models of abstractive text summarization.

자연어 처리를 위해서 두 문장의 의미 유사성을 분석하는 것은 아주 중요하다. 이 논문은 패러프레이즈 검출 태스크를 수행하기 위한 Paraphrase-BERT를 제안한다. 우선 구글이 제안한 사전 학습된 BERT를 그대로 이용해서 패러프레이즈 데이터 (MRPC)를 가지고 파인 튜닝하였고 추가적으로 최근에 구글에서 새로 발표한 Whole Word Masking 기술을 사용하여 사전 학습된 BERT 모델을 새롭게 파인 튜닝하였다. 그리고 마지막으로 다중 작업 학습을 수행하여 성능을 향상시켰다. 구체적으로 질의 응답 태스크와 패러프레이즈 검출 태스크를 동시에 학습하여 후자가 더 잘 수행될 수 있도록 하였다. 결과적으로 점점 더 성능이 개선되었고 (11.11%의 정확도 향상, 7.88%의 F1 점수 향상), 향후 작업으로 파인 튜닝하는 방법에 대해서 추가적으로 연구할 계획이다.
