  • This study aimed to examine research trends related to Natural Language Processing (NLP) in science education by analyzing 37 domestic and international documents that utilized NLP techniques in the field of science education from 2011 to September 2023. In particular, the study systematically analyzed the content, focusing on the main application areas of NLP techniques in science education, the role of teachers when utilizing NLP techniques, and a comparison of domestic and international perspectives. The analysis results are as follows: Firstly, it was confirmed that NLP techniques are significantly utilized in formative assessment, automatic scoring, literature review and classification, and pattern extraction in science education. Utilizing NLP in formative assessment allows for real-time analysis of students' learning processes and comprehension, reducing the burden on teachers' lessons and providing accurate, effective feedback to students. In automatic scoring, it contributes to the rapid and precise evaluation of students' responses. In literature review and classification using NLP, it helps to effectively analyze the topics and trends of research related to science education and student reports. It also helps to set future research directions. Utilizing NLP techniques in pattern extraction allows for effective analysis of commonalities or patterns in students' thoughts and responses. Secondly, the introduction of NLP techniques in science education has expanded the role of teachers from mere transmitters of knowledge to leaders who support and facilitate students' learning, requiring teachers to continuously develop their expertise. Thirdly, as domestic research on NLP is focused on literature review and classification, it is necessary to create an environment conducive to the easy collection of text data to diversify NLP research in Korea. Based on these analysis results, the study discussed ways to utilize NLP techniques in science education.

  • An nlp (Ner like protein) gene from E. coli was previously cloned and sequenced. Here we show that expression of the sugar metabolism related genes, lacZ, malQ and malP, increased 2.5-to 8.3-fold in the presence of a plasmid containing the nlp gene. This suggested that the nlp gene could induce maltose- and lactose-metabolism coordinately with crp*1 in the absence of cAMP. Using the nlp-lacZ fusion gene, it was possible to show the promoter of nlp was active in vivo.

  • In recent years, medical techniques have provided patients with various measures to improve their quality of life. For dental treatment, drug-mediated sedation techniques for relieving dental anxiety have been developed, but behavior control through drugmediation may be limited because of possible side effects, contraindications, and the additional expense to the patient. Many patients tend to avoid the treatment or are unwilling to accept it and this makes both patients and dentists feel pressured. The field of NLP application might alleviate this uncomfortableness. Recently, NLP has spread to the dental and medical field rapidly and has been used in surgical treatments as well as in direct psychotherapy. NLP techniques which could be applied to dental phobic patients are as follows. 1) anchoring, 2) dissociation, 3) submodality change, 4) time line threapy, 5) swish pattern, 6) six step reframing, 7) parts integration, 8) modeling and imagination and so on. The aim of this study is to examine the strategy of NLP psychology so that dental phobic patients can be treated efficiently and effectively by the application of behavior management. Through NLP, patients can be induced to have more positive attitudes and experiences in future dental treatment.

  • This paper describes our ongoing Korean-Chinese machine translation system, which is based on verb patterns. A verb pattern consists of a source language pattern part for analysis and a target language pattern part for generation. Knowledge description on lexical level makes it easy to achieve accurate analyses and natural, correct generation. These features are very important and effective in machine translation between languages with quite different linguistic structures including Korean and Chinese. We performed a preliminary evaluation of our current system and reported the result in the paper.

  • 질문 생성이란 구절이 입력되면 구절에서 답을 찾을 수 있는 질문을 자동으로 생성하는 작업으로 교육용 시스템, 대화 시스템, QA 시스템 등 다양한 분야에서 중요한 역할을 한다. 질문 생성에서 정답의 단어가 질문에 포함되는 문제점을 해결하기 위해 구절과 정답을 분리한다. 하지만 구절과 정답을 분리하게 되면 구절에서 정답의 정보가 손실되고, 정답에서는 구절의 문맥 정보가 손실되어 정답 유형에 맞는 질문을 생성할 수 없는 문제가 발생된다. 본 논문은 이러한 문제를 해결하기 위해 분리된 정답과 구절의 정보를 연결시켜주는 정답과 구절의 공동 주의 집중 계층을 제안한다. 23,658개의 질문-응답 쌍의 말뭉치를 이용한 실험에서 정답과 구절의 공동 주의 집중 계층이 성능 향상에 기여해 우수한 성능(BLEU-26.7, ROUGE-57.5)을 보였다.

  • In wide-ranging information society, fast and easy access to information in language of one's choice is indispensable, which may be provided by using various multilingual Natural Language Processing (NLP) applications. Natural language text contains references among different language elements, called anaphoric links. Resolving anaphoric links is a key problem in NLP. Anaphora resolution is an essential part of NLP applications. Anaphoric links need to be properly interpreted for clear understanding of natural languages. For this purpose, a mechanism is desirable for the identification and resolution of these naturally occurring anaphoric links. In this paper, a framework based on Hobbs syntactic approach and a system developed by Lappin & Leass is proposed for resolution of reflexive anaphoric links, present in Urdu text documents. Generally, anaphora resolution process takes three main steps: identification of the anaphor, location of the candidate antecedent(s) and selection of the appropriate antecedent. The proposed framework is based on exploring the syntactic structure of reflexive anaphors to find out various features for constructing heuristic rules to develop an algorithm for resolving these anaphoric references. System takes Urdu text containing reflexive anaphors as input, and outputs Urdu text with resolved reflexive anaphoric links. Despite having scarcity of Urdu resources, our results are encouraging. The proposed framework can be utilized in multilingual NLP (m-NLP) applications.

  • In modern society, messenger services are necessary to communication with others, and criminals are no exception. In representative cases of Burning Sun Gate(2018) and NthRoom(2019), messenger data analysis was used as a smoking gun to solve these criminal cases. Therefore messenger text analytics is critical for the resolution of crimes in a modern environment. also, it takes a lot of time to analyze messenger data in the digital forensic investigation process, so researchers in text mining need to be more effective to respond with the current situation In this paper, we study various natural language preprocessing(NLP) methods according to the characteristics of instant messages to effectively proceed with NLP analysis on instant messengers.

  • Records have temporal characteristics, including the past and present; linguistic characteristics not limited to a specific language; and various types categorized in a complex way. Processing records such as text, video, and audio in the life cycle of records' creation, preservation, and utilization entails exhaustive effort and cost. Primary natural language processing (NLP) technologies, such as machine translation, document summarization, named-entity recognition, and image recognition, can be widely applied to electronic records and analog digitization. In particular, Korean deep learning-based NLP technologies effectively recognize various record types and generate record management metadata. This paper provides an overview of Korean NLP technologies and discusses considerations for applying NLP technology in records management. The process of using NLP technologies, such as machine translation and optical character recognition for digital conversion of records, is introduced as an example implemented in the Python environment. In contrast, a plan to improve environmental factors and record digitization guidelines for applying NLP technology in the records management field is proposed for utilizing NLP technology.
