  • Mathematics educators have emphasized the importance of language use in mathematics education. However, previous studies have predominantly focused on the spoken language used in mathematics classrooms, which provides limited information on the written language used by mathematics teachers. The written language reflects the characteristics of the teacher community and social, cultural, and political contexts. Moreover, the written language affects teachers' instructional practices and their students' mathematics learning experiences. Therefore, this study aims to review a study conducted by Lee and Kim (2022) investigating changes in mathematics teachers' pedagogical lexicons.

  • Constructing a bilingual multi-word lexicon is confronted with many difficulties such as an absence of a commonly accepted gold-standard dataset. Besides, in fact, there is no everybody's definition of what a multi-word unit is. In considering these problems, this paper evaluates and analyzes the context vector approach which is one of a novel alignment method of constructing bilingual lexicons from parallel corpora, by comparing with one of general methods. The approach builds context vectors for both source and target single-word units from two parallel corpora. To adapt the approach to multi-word units, we identify all multi-word candidates (namely noun phrases in this work) first, and then concatenate them into single-word units. As a result, therefore, we can use the context vector approach to satisfy our need for multi-word units. In our experimental results, the context vector approach has shown stronger performance over the other approach. The contribution of the paper is analyzing the various types of errors for the experimental results. For the future works, we will study the similarity measure that not only covers a multi-word unit itself but also covers its constituents.

  • Previous studies on the bilinguals' lexical selection have suggested some evidence in favor of language-specific hypothesis. The purpose of this study was to see whether Korean-English bilinguals' semantic systems of Korean and English are shared or separated between the two languages. In a series of picture-word interference tasks, participants were to name the pictures in Korean or in English with distractor words printed either in Korean or English. The distractor words were either semantically identical, related, unrelated to the picture, or nonexistant. The response time of naming was facilitated when distractor words were semantically identical for both same-(Naming pictures in English/korean with English/Korean distractor words) and different-language pairs(Naming pictures in English with Korean distractor words and vice versa). But this facilitation effect was stronger when naming was produced in their native language, which in this case was Korean. Also, inhibitory effect was shown when the picture and its distractor word were semantically related in both same- and different-language paired conditions. These results show that bilinguals'two lexicons compete to some extent when selecting the target word. In this viewpoint, it can be concluded that the lexicons of either languages may not be entirely but partly overlapping in bilinguals.

  • Coverage has been a constant thorn in the side of deployed deep linguistic processing applications, largely because of the difficulty in constructing, maintaining and domaintuning the complex lexicons that they rely on. This paper reviews various strands of research on deep lexical acquisition (DLA), i.e. the (semi-)automatic creation of linguistically-rich language resources, particularly from the viewpoint of DLA for precision grammars.

  • Creative thinking requires an ability to draw ideas on the given topic in a given time period with concentration. For this, the development process of design concept on the topic was collected through experiments and interviews targeting 10 fashion education experts and 10 clothing majors. After the analysis, the results are as follows: First of all, divergent thinking was done to find as many ideas and possibilities as possible at the step of expanding the topic by analogy. This showed characteristics of spreading thoughts through the spread of lexicon to professional field knowledge of learned, individual's cultural background, other art fields. Second, abstracted and designed words that are expanded and listed by the topic analogy were specified the topic gradually through the free combination method between lexicons. The sentences made by the combination of lexicons were interpreted through the serial listing method, in which the connection between sentences had the meaning of orderly cause and effect form, and the parallel listing method that treated information at once. Third, the few characteristics of the procedure that visualizing into the specific design are as follows. Firstly, the method to transform image that lexicon has into the one appropriate to the topic, the case that reflects external characteristics of selected designed word, and the case which reflects as the extrinsic expression of personal immanent and tactic desires. This study has its means to propose methods and directions to help create more creative and systematic ideas by analyzing the characteristics that appeared during the process of thinking language-oriented design.

  • The main goal of this research is to build a sentiment analysis system which automatically determines user opinions of the Stanford Sentiment Treebank in terms of three sentiments such as positive, negative, and neutral. Firstly, sentiment sentences are POS tagged and parsed to dependency structures. All nodes of the Treebank and their polarities are automatically extracted from the Treebank. We train two Support Vector Machines models. One is for a node level classification and the other is for a sentence level. We have tried various type of features such as word lexicons, POS tags, Sentiment lexicons, head-modifier relations, and sibling relations. Though we acquired 74.2% in accuracy on the test set for 3 class node level classification and 67.0% for 3 class sentence level classification, our experimental results for 2 class classification are comparable to those of the state of art system using the same corpus.

  • The objectives of this study were: 1) to develop the sensory lexicons of milk marketed in Korea, 2) to investigate the effects of pasteurization and milk composition on the sensory qualities of milk, and 3) to evaluate the correlation between descriptive analysis and the electronic nose method. Electronic nose and descriptive analyses were conducted to analyze the sensory characteristics of 14 milk samples. The 14 samples were provided from 4 manufacturers with different pasteurization methods, and varied in fat, calcium, and lactose content. Twenty-six sensory lexicons were developed to describe the sensory characteristics of the samples. The low temperature, long-time processed milk had a distinctive 'bi-rim' flavor regardless of the milk composition. The lactose-free milks were sweet, and the low-fat milks had relatively low intensities for most flavor attributes. The electronic nose method successfully grouped the milk samples primarily based on their composition, but grouped them weakly by pasteurization method.

  • Recently, it has been reported that the positive emotional responses from previously consumed food could be transferred to the new food, affecting the acceptance of the food. This study was conducted to develop emotional lexicons for evaluating consumers' emotional responses to the food. Focus group interviews were conducted using 15 Koreans and 23 Chinese consumers to elicit emotional terms for Korean food HMR products. Using 23 Chinese participants who did not participate in the previous interview, emotional terms were screened through discussions in an interview setting. An online survey among 50 Koreans and 50 Chinese was carried out to evaluate and verify the valence and arousal potential of the selected terms. Elicited emotional terms in these two countries had similar valence and arousal potentials. However, cross-cultural differences were also found, mostly in arousal potential. Therefore, interpretation should be done carefully when comparing emotional responses between Korean and Chinese subjects.

  • 기존의 대부분의 정보 검색 시스템은 문서에 대한 ‘자동 색인 단계’를 거쳐 질의자의 요구에 적합한 문서들을 추출하도록 되어 있다. 이 과정에서 얼마나 적합한 문서를 빠짐없이 검색하였는가 하는 문제가, 검색 시스템의 효율성들 판단하는 데 가장 중요한 열쇠가 된다. 이 글에서는 ‘명사’ 중심의 키워드 추출이 안고 있는 몇 가지 문제점들에 관해서 논의하였다. 즉, 합성어 키워드 구축의 필요성, 동사 구문 정보에 대한 필요성, 부사구 표현에 대한 기술 필요성, 그리고 발화 상황이 고려되어야 하는 점등이 검토되었고, 이에 관한 해결책으로, 어휘정보 및 어절 정보, 나아가 구문 정보들을 담고 있는, 보다 체계적인 한국어 사전 시스템이 구축되어야 함을 강조하였다.
