  • Knowledge is often represented as a set of rules or a semantic network in intelligent systems. Recently, ontology has been widely used to represent semantic knowledge, because it organizes thesaurus and hierarchal information between concepts in a particular domain. However, it is not easy to collect semantic relationships among concepts. Much time and expense are incurred in ontology construction. Collective intelligence can be a good alternative approach to solve these problems. In this paper, we propose a collective intelligence approach of Games With A Purpose (GWAP) to collect various semantic resources, such as words and word-senses. We detail how to construct the semantic information model or ontology from the collected semantic resources, constructing a system named FunWords. FunWords is a Korean lexical-based semantic resource collection tool. Experiments demonstrated the resources were grouped as common nouns, abstract nouns, adjective and neologism. Finally, we analyzed their characteristics, acquiring the semantic relationships noted above. Common nouns, with structural semantic relationships, such as hypernym and hyponym, are highlighted. Abstract nouns, with descriptive and characteristic semantic relationships, such as synonym and antonym are underlined. Adjectives, with such semantic relationships, as description and status, illustration - for example, color and sound - are expressed more. Last, neologism, with the semantic relationships, such as description and characteristics, are emphasized. Weighting the semantic relationships with these characteristics can help reduce time and cost, because it need not consider unnecessary or slightly related factors. This can improve the expressive power, such as readability, concentrating on the weighted characteristics. Our proposal to collect semantic resources from the collective intelligence approach of GWAP (our FunWords) and to weight their semantic relationship can help construct the semantic information model or ontology would be a more effective and expressive alternative.

  • 본 논문은 기계학습 기법에 기반한 웹문서 자동분류 시스템의 성능을 높이기 위한 새로운 형태의 특징가공 기법을 제안한다. 제안 기법은 하이퍼텍스트 웹문서에 대한 자동분류를 효과적으로 수행하기 위해 하이퍼링크 관계를 활용하여 특징 집합을 확장시킨다. 웹문서는 하이퍼링크 관계를 통해 서로 연결된 구조를 가지며, 그 관계는 많은 경우 연관도가 높은 문서들 간에 존재한다. 이러한 링크 정보가 분류모델의 주요 인자가 되는 특징 집합의 질을 높이는 중요한 역할을 수행할 수 있다. 제안 기법의 기본 아이디어는 워드넷 온톨로지를 기반으로 분류 대상 문서와 인접 문서들에 포함된 단어(특징)들 간의 의미적 유사도를 평가함으로써 다수의 특징들로 구성된 추상화된 개념적 특징을 생성하는 것이다. 여기서 유사도 함수는 워드넷 안에서 특징들 간의 상/하위어 관계 정보를 정량적으로 계산하게 된다. 분류모델의 구축시 추상화된 개념 특징은 일반 특징과 동일하게 간주하여 보다 정확한 분류 모델을 구축하는데 기여한다. Web-KB 문서집합을 이용한 실험을 통해 제안 기법이 기존 기법 보다 우수함을 보였다.

  • Hashtags (#) have received a great deal of attention from academia and industry as an effective digital tool for engaging social media users and facilitating electronic word-of-mouth for brands. We delved into motivations concerning people's brand-related hashtag-posting behavior on social media. The findings revealed three motivations for posting brand-related hashtags on social media: social acceptance, brand altruism, and incentive seeking. Additionally, we examined the relationships between motivations and brand relationship variables. The results showed that social acceptance and brand-related altruism predicted all of the five relationship variables (i.e., brand attitude, brand trust, brand affective and calculative commitment and brand loyalty), while incentive-seeking predicted brand calculative commitment and brand loyalty. The findings of the study provide some meaningful insights into the development of brand communication strategies and help marketers capitalize on social media platforms to achieve higher user involvement.

  • Nowadays Chinese society advocates a kind of principal thinking, which Chinese call it "harmony". The entire Chinese society is trying to build a so-called "harmonious society", that is, people live in harmony with the natural environment and carry out sustainable development; people live in harmony with others and build harmonious social relationships; people live in harmony with themselves and cultivate self-morality and enhance national self-quality. It can be seen that the word "harmony" runs through this thinking all the time. This paper aims at viewing Chinese people's philosophy in Ming Dynasty from the Piaohailu. Likewise, the starting points of the paper are also these three aspects which are people's relationships with nature, others and themselves. Based on this angle, it tries to conduct a simple analysis and study by taking Korean official Cui Pu's Piaohailu as the main historical data.

  • 정부의 행정 서비스를 보다 효과적이고 효율적으로 제공하는 것은 정부혁신의 핵심키워드이다. 이를 위한 수단으로 정부 공공기관들은 전사적 아키텍처(Enterprise Architecture)를 적극적으로 도입, 활용해야 한다. 전사적 아키텍처란 아직까지도 진화중인 개념으로 해당 기관 정보화 업무의 전 영역을 업무 프로세스(Business Processes), 정보 흐름 및 관계(Information Flow and Relationships), 애플리케이션(Applications),데이터 명세 및 관계(Date Descriptions and Relationships), 그리고 기술 하부구조(Technology Infrastructure)로 구분 짓고 각각을 구조화된 산출물로 정리함으로써 공공정보화의 청사진을 제시한다. 이렇게 구축된 아키텍처 결과물은 기관 내 뿐 아니라 타 기관 EA와의 연계를 통해 상호 운용되어야 하며, 이 과정에서 어휘의미중의성(Word Sense Ambiguation)등 상호운용성 문제가 핵심 이슈로 대두되리라 예상된다. 공공분야로 한정짓더라도 200여 정부부처 EA간의 상호운용성 문제는 정부조직 간 경계를 넘어 통합된 EA정보를 취합, 활용하는 데 있어 가장 큰 장애요인이 되리라 예상된다. 본 논문에서는 온톨로지를 사용하여 각기 서로 다른 EA간 상호운용성 문제를 해결하는 방안에 대해 논의하고자 한다.

  • 일본어와 한국어는 문법적으로 많은 유사점을 가지고 있다. 이러한 유사점을 잘 이용한다면 일한 기계번역 시스템에서 구문해석이나 의미해석의 상당한 부분을 생략할 수 있다. 몇 년 전부터 우리는 유사성을 이용하여 번역율을 높이는 방법으로 번역테이블을 이용한 일한기계번역 시스템을 연구해왔다. 그러나 이 시스템은 활용어미의 번역, 다의성 단어의 처리 등 및 가지 문제점을 가지고 있었다. 본 논문에서는 번역데이블을 이용하는 시스템을 개선하여 이웃하는 단어들과의 관계 정보를 이용한 일한 기계번역 시스템을 제안한다. 현재 시스템의 문제점들을 해결하기 위하여 우선 조사, 조동사의 접속정보를 최대한 이용한다. 또한, 번역 테이블을 엔트리테이블과 접속정보 테이블로 나누어 설계하여 번역의 효율을 높인다. 즉, 하나의 역어만 가지는 단어인 경우, 우리는 일한 직접 대응 방법을 이용하여 바로 번역하고 2개 이상의 역어로 번역되어야 할 경우만 접속 정보 값을 평가하여 가장 가능성이 높은 번역어를 선택하도록 한다.

  • On-line game business has emerged as the most lucrative entertainment industry, with over 4 million players in China, with more than 45% of the market dominated by Korean on-line games. While the interactive entertainment market continues to expand, with many new Korean on-line game publishers entering the market, relatively little is known about which factors influence online game players' behavioral intentions (i.e., intention to play, brand-identity, word of mouth, flow, etc.) in this area. It appears that in this extremely attractive and growing services segment, academics, as well as practitioners, would benefit from investigating the relationships among the players' intention to play, social norms, word of mouth, flow, and the impacts of several other key game-related constructs. A conceptual framework is proposed and a simultaneous equation model is developed. This paper develops the exploratory LISREL model for identifying the factors affecting the players' intention to play for on-line games. Based on data collected from on-line questionnaire survey in China, the validity of the model has been tested and interesting conclusions have been developed concerning the relationships between the game-related constructs. It is hoped that this result might provide the useful guidelines for developing the successful on-line game contents. With better understanding of the players' behavioral intentions, Korean on-line game developers should be able to penetrate the China market with sustainable advantage over their competition.
