Big data processing technology and artificial intelligence (AI) are increasingly attracting attention. Natural language processing is an important research area of artificial intelligence. In this paper, we use Korean news articles to extract topic distributions in documents and word distribution vectors in topics through LDA-based Topic Modeling. Then, we use Word2vec to vector words, and generate a weight matrix to derive the relevance SCORE considering the semantic relationship between the words. We propose a way to recommend documents in order of high score.

The purpose of this paper is to investigate the distribution of /ju/ in British English, especially after the coronal sonorants /n, l, /r/. The sequence /ju/ is related with vowels such as /u/, /ʊ/, and /ʊ/, and has occasioned a variety of conflicting analyses or suggestions. One of those is in which context /j/ is deleted if we suppose that the underlying form is /ju/. The context differs according to the dialect we deal with. In British English, it is known that /j/ is deleted always after /r/, and usually after /l/ when it occurs in an unstressed word-medial syllable. To check this well-known fact I searched OED Online (the 2nd Edition, 1989) for those words which contain /n, l, r/ + /ju, jʊ, u, ʊ, (j)u, (j)ʊ/ in their pronunciations, using the search engine provided by OED Online. After removing some unnecessary words, I classified the collected words into several groups according to the preceding sonorant consonants, the positions, and the presence (or absence) of the stress, of the syllable where /ju/ occurs. The results are as follows: 1) the deletion of /j/ depends on the sonorant consonant which /ju/ follows, the position where it occurs, and the presence of the stress which /ju/ bears; 2) though the influence of the sonorant consonants is strong, the position and stress also have non-trivial effect on the deletion of /j/, that is, the word-initial syllable and the stressed syllable prefer the deletion of /j/, and word-medial and unstressed syllable usually retain /j/; 3) the stress and position factors play their own roles even in the context where the effect of /n, l, r/ is dominant.

Many important terminologies in biomedical text are expressed as abbreviations or acronyms. We newly suggest a semantic link topic model based on the concepts of topic and dependency link to disambiguate biomedical abbreviations and cluster long form variants of abbreviations which refer to the same senses. This model is a generative model inspired by the latent Dirichlet allocation (LDA) topic model, in which each document is viewed as a mixture of topics, with each topic characterized by a distribution over words. Thus, words of a document are generated from a hidden topic structure of a document and the topic structure is inferred from observable word sequences of document collections. In this study, we allow two distinct word generation to incorporate semantic dependencies between words, particularly between expansions (long forms) of abbreviations and their sentential co-occurring words. Besides topic information, the semantic dependency between words is defined as a link and a new random parameter for the link presence is assigned to each word. As a result, the most probable expansions with respect to abbreviations of a given abstract are decided by word-topic distribution, document-topic distribution, and word-link distribution estimated from document collection though the semantic dependency link topic model. The abstracts retrieved from the MEDLINE Entrez interface by the query relating 22 abbreviations and their 186 expansions were used as a data set. The link topic model correctly predicted expansions of abbreviations with the accuracy of 98.30%.

This study set the research model to examine the correlation between Word-of-Mouth constraint factors, efforts to negotiate pertaining to these, Flow and Word-of-Mouth intent based on the theory of leisure constrain when it comes to the correlation between consumers' Word-of-Mouth constraint factors and Word-of-Mouth. Correlation among the variables were verified in an empirical manner. Results of this study are summarized as follows. After verifying the hypotheses, all the hypotheses were adopted excluding the hypotheses of two results (Hypothesis 1, hypotheses 5). Detailed results regarding this are as follows. First, the following is the effect of the Intrapersonal Constraint and Word-of-Mouth constraint factors on the Word-of-Mouth constraint negotiation effort. Interpersonal Constraint and Structural Constraint exert positive (-) effect on the Word-of-Mouth constraint negotiation effort. In case of Intrapersonal Constraint, negative (-) effect was demonstrated. Thus, this was statistically significant although dismissed from hypothesis verification. Second, the following is the result of examining the structural correlation between Word-of-Mouth constraint negotiation effort, Flow and Word-of-Mouth. Word-of-Mouth constraint negotiation effort exerts positive (-) effect on the Flow, but it was not statistically effective in case of the Word-of-Mouth. Lastly, it is possible to see that the Flow plays the role of a medium since it exerted positive (-) effect on the Word-of-Mouth. Results of this study are expected to provide key theoretical and working level implications as well as general understanding of the Word-of-Mouth constraint factors, consumers' Flow and Word-of-Mouth.

This is a study on village names in a plain region of Changnyeong-Gun, a mountain region of Bonghwa-Gun and an island region of Namhae-Gun. The three regions differ in geographical features. The data are based on 455 village names in Changnyeong-Gun, 552 village names in Bonghwa-Gun and 275 village names in Namhae-Gun found in the 1 : 50,000 topographic map. The method of this study is to analyze the word structures of village names in the five basic concepts in geography : Man-Land(Natural Environment and Human Activities). Spatial Relation, Distribution, Region and Transition. The main results of this study are as follows: 1. Naming of villages are related to Natural Environment(41%), Human Activities(23%), Region(17%), Spatial Relation(13%), Distribution(5%), and Transition(3%). Of these six factors, Changnyeong-Gun is relatively dominant in village names related to Spatial Relations, Region and Transition ; Bonghwa-Gun Natural Environment and Namhae-Gun Human Activities and Spatial Relations. But the three Guns are absolutely dominant in village names related to Natural Environment and Human Activities. 2. A village name is divided into the specific name part(given name) and the generic name part(classified name). Names related to Human Activities, Spatial Relations, Distribution and Transition are more frequently found in the specific name part. Therefore, they are used as the given name of a village name. Whereas names related to Natural Environment and Region are more frequently found in generic name part, which means that they are used as the classified name of a village. 3. The word structure of a village name usually has two parts a frontal part(given name) and a rear part(classified name). The two parts have a particular pattern in the geographic concept when they are combined. 1) In the village names related to in their frontal part of the word structure, is more frequently combined as their rear part in Bonghwa-Gun, in Namhae-Gun and in Changnyeong-Gun. 2) In the village names related to in their frontal part of the word structure, is more frequently combined as their rear part in Changnyeong-Gun, in Namhae-Gun and in Bonghwa-Gun. Accordingly, Man(Human Activities) - Land (Natural Environment) can be considered the most important concept in the naming of villages, because the concept is most frequently used in the word structures of village names.

Purpose - Despite that the importance of small enterprises' performance in the community has been magnified, no study has been conducted yet on the performance based on consumers directly faced by small enterprises. Accordingly, this study aims to investigate the relationship between the life styles of consumers who use small enterprises' stores by type and the word of mouth(WOM) effects, which are concrete behaviors of consumers. Research design, data, and methodology - The VALS classification system was utilized to classify the types of life styles of consumers who use small enterprises' stores. The consumers were divided into a total of four types. This study was intended to investigate the effects of the types of consumers on the word of mouth(WOM) effects of consumers who use small enterprises' stores along with the effects of consumers' perception of economic situations on their word of mouth(WOM) effects after using small enterprises' stores. Results - The results of the study indicated that among the types of consumers who use small enterprises' stores, the group that pursues faith and the group that pursues knowledge had positive (+) effects on favorable word of mouth(WOM) effects. However, the group that pursues trends and the group that pursues action were shown to have no effect and positive or negative perceptions of economic situations were shown to have no effects of the word of mouth(WOM) effects of users of small enterprises' stores. Conclusions - In this study, as a measure to create small enterprises' performance, word of mouth(WOM) effects on small enterprises' stores according to consumers' consumption behaviors were examined focusing on consumers. Through the study results, the groups of consumers who use small enterprises' stores by type that provide favorable word of mouth(WOM) effects were derived. And This Study aims to investigate the relationship between the four type life styles of consumer who use small enterprises' stores and the word of mouth(WOM) effect. Accordingly This study is significant in that it derived a measure to create small enterprises' performance centering on consumers and that it presented a cornerstone for the establishment of small enterprises at the government level.

Purpose: This research aims to explain the influence of social media influencer (SMI), electronic word of mouth (EWOM), and perceived quality (PQ) on purchase intention (PI) of beauty products on YouTube. Youtube as the number 1 social media in Indonesia, has an important role as a promotional strategy media for beauty products. Research design, data and methodology: This study used the online survey to 210 female respondents aged 17-30 years who became a subscriber of an Indonesian beauty influencer. Simple regression and multiple regressions were performed to analyze the independent variables towards the dependent variable. Results: The results show that social media influencer, electronic word of mouth, and perceived quality simultaneously have a significant influence on purchase intention. Nevertheless, only two variables individually have a significant influence on purchase intention, which is social media influencer and perceived quality. Conclusions: Perceived quality and social media influencer could be the best strategies to increase consumers when promoting through the influencer's Youtube channel by utilizing a subscriber. While e-WOM can be influential on other social media platforms rather than on the Youtube platform. Therefore, suggested that digital marketer must use multiple social media platforms to increase consumers' purchase intention.
