  • The purpose of this study is to compare the complexity of language level between verbally-precocious and typically-developing children from 2 to 3 years-old. Participants were 15 children classified as verbally-precocious were scored at the mean 56.85(expressive language) and 88.82(receptive language), and another 15 children classified as typically developing did at the mean 33.51(expressive language) and 58.01(receptive language) on MCDI-K. Each child's spontaneous utterances in interaction with her caregiver were collected at three different times with 6 months interval. All of the utterances were transcribed and analyzed for the use of MLU and lexical diversity by using KCLA. Summarizing the overall results, verbally-precocious children had significantly higher language abilities than typically-developing children at each time, and there were significant differences between two groups in syntactic and semantic language development, showing that verbally-precocious children indicated distinctive MLU and lexical diversity. These results suggest a high degree of stability in precocious verbal status, with variations in language complexity during conversations contributing to later differences in their language ability.

  • Many researchers have carried out studies related to programming languages since the beginning of computer science. Besides programming with traditional programming languages (i.e., procedural, object-oriented, functional programming language, etc.), a new paradigm of programming is being carried out. It is programming with natural language. By programming with natural language, we expect that it will free our expressiveness in contrast to programming languages which have strong constraints in syntax. This paper surveys the approaches that generate source code automatically from a natural language description. We also categorize the approaches by their forms of input and output. Finally, we analyze the current trend of approaches and suggest the future direction of this research domain to improve automatic code generation with natural language. From the analysis, we state that researchers should work on customizing language models in the domain of source code and explore better representations of source code such as embedding techniques and pre-trained models which have been proved to work well on natural language processing tasks.

  • Specific Language Impairment is one of the serious disorders that interferes with spontaneous communication skills in children. Children suffering from this disorder may have reading, speaking, or listening impairments, and such type of disorders are also termed Autism Speech Disorder (ASD) in medical terminology. The aim of the article is to define specific language impairment in children and the problems it can cause. The different methods adopted by speech pathologists to diagnose language impairment. Finally implementing machine learning models to automate the process and help speech pathologists and pediatricians/ in diagnosing the specific language impairment.

  • The main purpose of the article is to study the peculiarities of the work of the Ukrainian language in the upper grades of the lyceum based on the activity approach. Despite the fact that a number of scientific studies and applied developments on teaching Ukrainian as a foreign language have recently appeared in Ukrainian linguistics, significant problems in this area should be recognized (organization of the educational process when learning a language as a foreign language, general methodological principles, psycho- and sociolinguistic foundations, communicative approaches), the non-resolution of which leads to methodologically unreasonable teaching of the Ukrainian language as a foreign language, the use of methods of teaching the language as a native language or the study of the language as a subject (linguistic aspect). In addition, due attention is not paid to the development of communication skills, which, firstly, worsens the quality of teaching and learning. Based on the results of the analysis, the key aspects of the work on the Ukrainian language in the senior classes of the lyceum were analyzed on the basis of an activity approach.

  • In this paper, we propose a language modeling approach to improve the performance of a large vocabulary continuous speech recognition system. The proposed approach is based on the active learning framework that helps to select a text corpus from a plenty amount of text data required for language modeling. The perplexity is used as a measure for the corpus selection in the active learning. From the recognition experiments on the task of continuous Korean speech, the speech recognition system employing the language model by the proposed language modeling approach reduces the word error rate by about 6.6 % with less computational complexity than that using a language model constructed with randomly selected texts.

  • 본 연구는 자연어 질의의 형태 및 구문 정보를 바탕으로 불리언 질의를 생성하는데 그 목적을 둔다. 일반적으로 대부분의 상용정보검색시스템은 입력형식을 검색성능이 종은 불리언 형태로 하고 있으나, 일반 사용자는 자신이 원하는 정보를 불리언 형태로 표현하는데 익숙하지 않다. 그러므로 본 정보검색시스템은 자연어 질의를 기본 입력형태로 하여 사용자의 편의성을 높이고, 이 질의를 범주문법에 기반한 구문분석 결과에 의해 복합명사를 고려한 불리언 형태로 변환하여 검색을 수행함으로써 시스템의 검색 성능의 향상을 도모하였다. 정보검색 실험용 데이터 모음인 KTSET2.0으로 실험한 결과 본 논문에서 제안한 자연어 질의로부터 자동 생성된 불리언 질의의 검객성능이 KTSET2.0에서 제공하는 수동으로 추출한 불리언 질의보다 8% 더 우수한 성능을 보였고, 기존 자연어질의 시스템이 수용해온 방법인 형태소 분석을 거쳐 불용어를 제거한 후 Vector 모델을 적용하여 검색을 수행한 경우보다는 23% 더 나은 성능을 보였다.

  • In the case of a hearing impaired person using sign language, there are many difficulties in communicating with a normal person who does not understand sign language. The sign language translation system is a system that enables communication between the hearing impaired person using sign language and the normal person who does not understand sign language in this situation. Previous studies on sign language translation systems for communication between normal people and hearing impaired people using sign language are classified into two types using video image system and shape input device. However, the existing sign language translation system does not solve such difficulties due to some problems. Existing sign language translation systems have some problems that they do not recognize various sign language expressions of sign language users and require special devices. Therefore, in this paper, a sign language translation system using an artificial neural network is devised to overcome the problems of the existing system.

  • Dependency parsing is an important task in natural language processing whose results are used in many downstream tasks such as machine translation, information retrieval, relation extraction, question answering and many others. Most of the dependency parsing literature focuses on using end-to-end and sequence-to-sequence neural architectures as the core of the system. One such system, namely Biaffine dependency parser is explored in the current paper for effective dependency parsing of Korean language.

  • The paper argues for the necessicity of revising many fundamental concepts that we use in everyday situations and in communication such as reality, thought, language, the world and finally the truth. The paper develops the argument that what the word ′truth′ actually signifies cannot be addressed just by explicating what philosophy, science or even religion denote but that it can only be answered fully by the study of language and therefore in a larger context linguistics. Language is the very tool that enriches the communication between one another due to its diverse significations that one may use when expressing one′s views, thereby making life more enjoyable. The paper develops why the above corresponding argument should be justified by developing three outstanding views as follows. The world or reality is indistinguishable from the common worldview that we associate with without the means of language. That the worldview is in essence inseparable from the mental and intellectual representation of it and the only means of expression lies with language. And finally, that the language is a complex signification in itself in every aspect. Language in short is the very essence of what we define as being ′poetic.′ With these arguments in mind, we may once again ponder the signification of Nietzsche′s words when he states that "to see science through the lens of art, and art through the lens of life."
