Conducting sentiment analysis and opinion mining are challenging tasks in natural language processing. Many of the sentiment analysis and opinion mining applications focus on product reviews, social media reviews, forums and microblogs whose reviews are topic-similar and opinion-rich. In this paper, we try to analyze the sentiments of sentences from online webcast reviews that scroll across the screen, which we call live barrages. Contrary to social media comments or product reviews, the topics in live barrages are more fragmented, and there are plenty of invalid comments that we must remove in the preprocessing phase. To extract evaluative sentiment sentences, we proposed a novel approach that clusters the barrages from the same commenter to solve the problem of scattering the information for each barrage. The method developed in this paper contains two subtasks: in the data preprocessing phase, we cluster the sentences from the same commenter and remove unavailable sentences; and we use a semi-supervised machine learning approach, the naïve Bayes algorithm, to analyze the sentiment of the barrage. According to our experimental results, this method shows that it performs well in analyzing the sentiment of online webcast barrages.

Brand image refers to how customers, stakeholders and the market see and recognize the brand. A positive brand image leads to continuous purchases, but a negative brand image is directly linked to consumers' buying behavior, such as stopping purchases, so from the corporate perspective, it needs to be quickly and accurately identified. Currently, methods of investigating brand images include surveys and SNS surveys, which have limited number of samples and are time-consuming and costly. Therefore, in this study, we are going to conduct an emotional analysis of text data on social media by utilizing the machine learning based KoBERT model, and then suggest how to use it for game corporate brand image analysis and verify its performance. The result has proved some degree of usability showing the same ranking within five brands when compared with the BRI Korea's brand reputation ranking.

Fashion illustration is a language that expresses the inspirational imagination of designers. Like fashion, illustration reflects and records the social and cultural phenomena of the time. In this context, Ignasi Monreal's fashion illustration shows the characteristics that reveal modern people's ways of thinking and their desires. This study analyzed work by Ignasi Monreal in 'Gucci Hallucination' of 2018 S/S to examine the characteristics of his new painting style and the messages his fashion illustration aims to convey. He tried to harmonize his surrealistic digital illustrations of Greek mythology with Gucci items. As a result of this study, the characteristics of Monreal's illustration works were divided into two main categories: formal aspects (similarity of composition or subject and use of dépaysement techniques), and content aspects (expression of a mythical surreal being). These qualities differentiate Monreal's fashion illustration from that of other artists. In addition, his works on the myth of Icarus not only express the desires of modern people but also convey social satirical messages.

The words a speaker uses can be regarded as the core, the main issue and a symbolic icon of what he says. Applying this to presidents' addresses of each English literary society in Korea shows that frequency in use and the linkage of words they use in their addresses are value and ideas executive officers pursue. The purpose of this study is to analyze the contents of presidents' addresses introduced in home page of each English literary society in Korea and investigate features and constitution of them each, focusing on analysis of a language network. The results of this study show the features of resemblances and differences of commonly-used words. In addition, these results appear to suggest that they can be also applied to a comparative study between the English literary societies in Korea.

Arif Dirlik in Postmodernity's Histories sees the issue of re-ethnicization in the case of John Huang, China's alleged attempt at lobbying the Clinton administration. In this view, Americans with Chinese surnames were suspected by the US Justice Department to be possible spies working for Beijing. Reethnicization here seems to serve the mainstream society in reducing an ethnic minority to a group of aliens operating for their countries of origin. However, re-ethnicization is not necessarily a one-way oppressive operation; it is often made use of by the ethnic minorities in their efforts to adapt to their country of arrival. Haroon and Karim, the protagonists of Hanif Kureishi's The Buddha of Suburbia, are cases in point. They are portrayed as winning social recognition and securing a place of their own within the hostile host society through a strategic use of re-ethnicization, that is, masquerading as 'genuine Orientals.' This study brings to light possible fallacies or misguided expectations concerning the political position of first- and second-generation immigrants. One of the fallacies is found in the racist metropolis, which regards the ethnic minorities as a sort of resident aliens, no matter what immigrant generation the latter belongs to. Another fallacy is found in the kind of postcolonial criticism that automatically regards an anti-racist critique advanced by people like Kureishi as something motivated by a confrontational tactic, that is, an attempt at subverting the colonial power relations. The conclusion of this study is that Kureishi's agenda, as presented in The Buddha of Suburbia, is neither the preservation of an ethnic identity nor the subversion of colonial power relations but survival in the metropolis. On this account Kureish's agenda can be called a micro-politics.

This study aims to provide research fields and topics to complement, extend and develop the geographical toponymy in Korea, largely based on a summary of topics discussed in the United Nations Group of Experts on Geographical Names (UNGEGN). The Korean toponymic research has generally focused on revealing human, social and physical characteristics of the region by investigating the creation and change of the geographical names, with the perspective of creator and owner of the toponyms. Toponymic researches in the UNGEGN, in comparison, have put forward with the mission of standardization of geographical names and with specific emphasis on the users of toponyms. The topics include diverse forms of toponyms by user groups, roles of language groups, preservation of toponyms with specific value, etc. As research directions for an establishment of extended geographical toponymy accommodating discussions in the UNGEGN, further research topics are suggested; use of exonyms and endonyms in the Korean language, the nature of geographical feature and perception over it, writing systems for inter-language communication, and geographical names as intagible cultural heritage.

Since the introduction of web 2.0 technology, social network service has been recognized as the foundation of an important future information technology. The advent of web 2.0 has led to the change of content creators. In the existing web, content creators are service providers, whereas they have changed into service users in the recent web. Users share experiences with other users improving contents quality, thereby it has increased the importance of social network. As a result, diverse forms of social network service have been emerged from relations and experiences of users. Social network is a network to construct and express social relations among people who share interests and activities. Today's social network service has not merely confined itself to showing user interactions, but it has also developed into a level in which content generation and evaluation are interacting with each other. As the volume of contents generated from social network service and the number of connections between users have drastically increased, the social network extraction method becomes more complicated. Consequently the following problems for the social network extraction arise. First problem lies in insufficiency of representational power of object in the social network. Second problem is incapability of expressional power in the diverse connections among users. Third problem is the difficulty of creating dynamic change in the social network due to change in user interests. And lastly, lack of method capable of integrating and processing data efficiently in the heterogeneous distributed computing environment. The first and last problems can be solved by using FOAF, a tool for describing ontology-based user profiles for construction of social network. However, solving second and third problems require a novel technology to reflect dynamic change of user interests and relations. In this paper, we propose a novel method to overcome the above problems of existing social network extraction method by applying FOAF (a tool for describing user profiles) and RSS (a literary web work publishing mechanism) to OLAP system in order to dynamically innovate and manage FOAF. We employed data interoperability which is an important characteristic of FOAF in this paper. Next we used RSS to reflect such changes as time flow and user interests. RSS, a tool for literary web work, provides standard vocabulary for distribution at web sites and contents in the form of RDF/XML. In this paper, we collect personal information and relations of users by utilizing FOAF. We also collect user contents by utilizing RSS. Finally, collected data is inserted into the database by star schema. The system we proposed in this paper generates OLAP cube using data in the database. 'Dynamic FOAF Management Algorithm' processes generated OLAP cube. Dynamic FOAF Management Algorithm consists of two functions: one is find_id_interest() and the other is find_relation (). Find_id_interest() is used to extract user interests during the input period, and find-relation() extracts users matching user interests. Finally, the proposed system reconstructs FOAF by reflecting extracted relationships and interests of users. For the justification of the suggested idea, we showed the implemented result together with its analysis. We used C# language and MS-SQL database, and input FOAF and RSS as data collected from livejournal.com. The implemented result shows that foaf : interest of users has reached an average of 19 percent increase for four weeks. In proportion to the increased foaf : interest change, the number of foaf : knows of users has grown an average of 9 percent for four weeks. As we use FOAF and RSS as basic data which have a wide support in web 2.0 and social network service, we have a definite advantage in utilizing user data distributed in the diverse web sites and services regardless of language and types of computer. By using suggested method in this paper, we can provide better services coping with the rapid change of user interests with the automatic application of FOAF.

This study investigated the factors that influence subjective well-being of immigrant wives in Korea. We initially grouped the factors into 3 categories: personal, domestic, and social. For personal factors, we included couple's age difference, reason for entry, religion, marital duration, employment status, economical status, acculturation to Korean culture, acquisition of Korean language, and ego-resiliency. For domestic factors we included marriage process, reason for marriage, husbands' understanding of wife's native language, husbands' understanding of wife's culture, marital satisfaction, existence of children, head of the household, and parenting efficacy. Finally for social factors, awareness of welfare services and systems, use of public institutions and civil organizations, and participation in social groups were included. We recruited 256 immigrant wives who live in Asan City, Chungnam Province and the data were analyzed by multiple linear regression. The factors that statistically significant were: ego-resiliency, marital duration, acculturation to Korean culture and economic status among personal factors; parenting efficacy, marital satisfaction and marriage process (married without a matchmaker) among domestic factors; participation in self-help group of women from the same mother country, awareness of welfare services and systems, participation in hobby club, and participation in fraternal/religious society among social factors. It is hoped that this paper will yield general insights into subjective well-being of immigrant wives and may help them to develop inner talent and strength.

This paper has an aim to examine English native speakers' requests, and offer an instructional technique to develop EFL students' pragmatic ability. For this purpose, English-speaking native speakers' requests were collected in six different face-threatening situations, and analyzed in three ways: directness levels, internal modification and sequence of request. The analysis of requests showed that they were realized mainly through conventionally indirect level in most situations, were internally modified frequently through the use of downgraders, and had a certain sequence of utterances realizing a request. On the basis of these findings, two kinds of interactional activities (Jigsaw and pair work) were provided as sample activities to promote EFL students' pragmatic knowledge about the appropriate ways of making requests given the fact that pragmatic errors can be more serious and more problematic than grammatical errors in social interaction.

Social media holds the potential to facilitate vertical political communication by giving citizens the opportunity to interact directly with their representatives. However, skeptics claim that even when politicians use "interactive media," they avoid direct engagement with constituents, using technology to present a façade of interactivity instead of a genuine dialogue. This study explores how elected officials in three regions of the world are using Twitter to interact with the public. Using the Twitter activity of 15 officials over a period of six months, we show that in addition to the structural features of Twitter that are designed to promote interaction, officials rely on language to foster or to avoid engagement. We also provide evidence that the existence of interactive features does not guarantee interactivity.
