Word sense disambiguation(WSD) that determines the exact meaning of homonym which can be used in different meanings even in one form is very important to understand the semantical meaning of text document. Many recent researches on WSD have widely used NNLM(Neural Network Language Model) in which neural network is used to represent a document into vectors and to analyze its semantics. Among the previous WSD researches using NNLM, RNN(Recurrent Neural Network) model has better performance than other models because RNN model can reflect the occurrence order of words in addition to the word appearance information in a document. However, since RNN model uses only the forward order of word occurrences in a document, it is not able to reflect natural language's characteristics that later words can affect the meanings of the preceding words. In this paper, we propose a WSD scheme using Bidirectional RNN that can reflect not only the forward order but also the backward order of word occurrences in a document. From the experiments, the accuracy of the proposed model is higher than that of previous method using RNN. Hence, it is confirmed that bidirectional order information of word occurrences is useful for WSD in Korean language.

We aimsto examine the determinants of visitors' positive word-of-mouth (WOM) in a web-based virtual reality contemporary art exhibition. We also examines the effects of 3 realms of experience (entertainment, esthetic, escapist) on emotional arousal, how this emotional arousal affects memory and positive word-of-mouth, how memory affects positive word-of-mouth and how age moderate all of the paths. We examined a total of 297 visitors and was conducted through an online survey focusing on Chinese users of ages 20-49. The analysis results showed that entertainment and esthetic have an effect on emotional arousal, but escapist did not. The results also showed emotional arousal has an effect on memory and positive WOM. Memory did not affect positive word-of-mouth. Finally, age has a moderate effect on all the paths, except for the path form escape towards emotional arousal and memory to positive word-of-mouth. The theoretical implications of this study are meaningful exhibition research. While, it also will be helpful to segment the web-based virtual reality art exhibition visitors by dividing into 3 groups (20s, 30s, 40s) and to provide marketing and operation strategies.

본 논문에서는 자료 조사를 위한 최적의 키워드 추출 및 검색 방법을 제안하였으며, 북한 건설 관련 동향 파악을 예시로 제안 방법을 검증하였다. 대표적인 국내 언론 플랫폼인 빅카인즈(BigKinds)를 활용하여 표본 기사를 선정하고 키워드를 추출하였다. 추출된 키워드는 워드 임베딩(Word Embedding)을 활용하여 벡터화하였으며, 이를 토대로 코사인 유사도(Cosine Similarity)를 통해 추출된 키워드 간의 유사도를 검사하였다. 또한 상위 빈도수 10개에 대한 키워드를 기준으로 유사도 0.5 이상인 키워드들을 군집화하였다. 각 군집들은 빅카인즈 검색 양식에 맞추어 군집 내부 키워드 간에는 'OR', 군집 간에는 'AND'로 형성하였다. 심층 분석 결과, 본래 목적에 맞는 유의미한 기사들이 추출되었음을 확인할 수 있었다. 기존의 분류체계 및 검색 양식을 변형시키지 않은 상태에서 사용자의 세부 목적을 충족시키는 자료 조사·분류가 가능하게 되었다는 점에서 의의를 갖는다.

This study is concerned with the julpoong of Koguryo. The meaning, form, structure, user, the origin of the word the julpoong were examined. The pien of he ancient China and the julpoong of Koguryo were examined. The result of the analysis of this study is as follows. The Chinese and the people of Koguryo used the meanings of the julpoong differently : the Chinese referred the julpoong to the conical hat with the seams including one seam on it, while the people of Koguryo called the julpoong as the conical hat with seams excluding one seam on it. the people of Koguryo called the julpoong with one seam as the chack . The julpoong was used by all people of Koguryo : the government officials, envoys, and the commoners wore it. The word julpoong of Koguryo was derived from dulband, dulband, dubend, dolband of Persians. the word julpoong is correspondent with the above the persian words. The julpoong of Koguryo word was transliteration of dulband(dulband, dulbend, dolband) meaning turban or sash. The hat called chack by the people of 고구려 was the conical hat with one sea and their meaning of he chack was different from the meaning of the chack of the Chinese. The julpoong a kind of conical hat, was called by the pine by the ancient Chinese.

The regularity effect for printed word recognition and naming depends on ambiguities between single letters (small grain-size) and their phonemic values. As a given word is repeated and becomes more familiar, letter-aggregate size (grain-size) is predicted to increase, thereby decreasing the ambiguity between spelling pattern and phonological representation and, therefore, decreasing the regularity effect. Lexical decision and naming tasks studied the effect of repetition on the regularity effect for words. The familiarity of a word from was manipulated by presenting low and high frequency words as well as by presenting half the stimuli in mixed upper- and lowercase letters (an unfamiliar form) and half in uniform case. In lexical decision, the regularity effect was initially strong for low frequency words but became null after two presentations; in naming it was also initially strong but was merely reduced (although still substantial) after three repetitions. Mixed case words were recognized and named more slowly and tended to show stronger regularity effects. The results were consistent with the primary hypothesis that familiar word forms are read faster because they are processed at a larger grain-size, which requires fewer operations to achieve lexical selection. Results are discussed in terms of a neurobiological model of word recognition based on brain imaging studies.

In China, E-commerce live broadcast has emerged as the most popular and innovative online shopping form for today's consumers, and its "real-time interactive" feature can compensate for the communication delays of general online shopping. Based on the author's previous research it has been demonstrated that, in the E-commerce live broadcast environment, Internet Word of Mouth (IWOM) has become an important reference for consumers when making purchases. In this paper, we reconstructed the "IWOM-Purchase Intentions" model and use interaction (Auchor-Audience and Audience-Audience) as a mediating variable to empirically investigate the impact of IWOM on purchase intentions in E-commerce live broadcast. The data were collected through a questionnaire survey of individuals who had experience in E-commerce live broadcast and 250 valid data were obtained and analyzed by SPSS21.0. The results show that: the interaction (Auchor-Audience) acts as a mediator between IWOM (strength of relationship; word-of-mouth quality and word-of-mouth timeliness) and purchase intention; And the interaction (Audience-Audience) acts as a mediator between word-of-mouth timeliness on purchase intention, but has no significant mediation on the impact on the strength of relationship and word-of-mouth quality to purchase intention. On this basis, recommendations are made for the implementation of IWOM marketing strategies for E-commerce live broadcast platforms and anchors.

본 논문에서는 버티컬 무소음 마우스 10,000건에 대한 웹크롤링을 통해 수집된 정형화된 데이터셋을 Word2Vec을 이용하여 단어 간 유사도분석을 시행하고 컴퓨터공학과 대학생 92명에게 5일 동안 제시된 상품을 사용하게 하고 자가보고식 설문 분석을 시행하도록 하였다. 설문 분석은 서술식 형태로 수집하여 단어빈도 분석과 단어 간 유사도분석에서 추출된 상위 50개 단어를 제시하고 선택하는 방식으로 이루어졌다. 전자상거래 사용자 상품평 유사도 분석결과 내용 중 클릭 키워드에 대한 장점으로 통증(.985), 디자인(.963)가 분석되었으며 단점은 가볍다(.952), 적응(.948)이었다. 서술식 빈도분석에서는 버티컬(123개), 통증(118개)이 가장 많이 선택 되었으며 장/단점 유사단어를 선택에 해당되는 장점에서는 버티컬(83개), 통증(75개) 선택 되었으며 단점에서는 적응(89개), 버튼(72개)이었다. 따라서 본 연구에서 적용한 방식을 상품기획 프로세스의 신상품 개발 및 기존 상품의 검토 전략으로 반영 시 중견기업, 중소기업의 의사결정자와 상품기획자는 의사결정에 중대한 자료로 활용 할 수 있을 것으로 기대된다.

The issues in polysemy with respect to the verbs in WordNet will be discussed in this paper. The hypernymy/hyponymy structure of the multiple senses is observed when we try to build a bilingual network for Chinese and English. There are several types of polysemic patterns and a co-hypernym may have the same word form as its subordinates. Fellbaum (2000) dubbed autotroponymy that the verbs linked by mailer relation share the same verb form. However, her syntactic criteria seem not compatible to the hierarchies in WN. Either the criteria or the network should be reconducted. For most verbs in WN 1.7, polysemous relations are unlikely to extend over 3 levels of IS-A relation. Highly polysemous verbs are more complicated and may be involved in certain semantic structures. Semi-automatic sense grouping may be helpful for multimlinguital information retrieveal.

문자는 의사소통의 중요한 매개체 중 하나로 사람이 문자를 인식할 때, 글자의 크기나 모양, 위치, 글 자체 등의 매우 다양한 지각적인 변화에 의한 영향을 크게 받지 않는다. 이는 문자에 대한 처리가 다른 사물과는 다소 다르게 일어나며 머릿속에 추상적인 형태(abstract form)로 저장되어 있음을 의미한다. 이러한 처리과정은 시각단어재인 과정에서 어휘 지식에 접근하기 위한 중요한 단계로 여겨지면서 이와 관련된 대뇌 영역의 국재화 양상에 대한 연구들이 진행되고 있다. 본 연구에서는 한글 시각단어재인에 있어 Cohen과 Dehaene 등이 'visual word form area'주장하고 있는 좌측 ventral occipito-tempoarl region의 대뇌 활성화 양상을 살펴보았다. 실험 결과, 좌측 'VWFA'는 어휘의 친숙성에 우뇌의 대측 지점은 어휘성(lexicality)에 민감한 것으로 나타났다.
