Learning user's preference is a key issue in intelligent system such as personalized service. The study on user preference model has adapted simple user preference model, which determines a set of preferred keywords or topic, and weights to each target. In this paper, we recommend multi-perspective user preference model that factors sentiment information in the model. Based on the topicality and sentimental information processed using natural language processing techniques, it learns a user's preference. To handle timc-variant nature of user preference, user preference is calculated by session, short-term and long term. User evaluation is used to validate the effect of user preference teaming and it shows 86.52%, 86.28%, 87.22% of accuracy for topic interest, keyword interest, and keyword favorableness.

The purpose of this study was to explore the characteristics of the urban apartment dwellers' favorite interior design Interior design was examined by renovation, the amibience, the color and the materials ofliving room. Questionnaire survey method was used in this research. By random sampling, 2, 609 apartment dwellers from Seoul. Pusan, Kwangju and Cheonan were selected. On the basis of findings of this study, conclusions were drawn as follows: By regional comparison, the dwellers of Seoul have a tendency to prefer elegant space, those of Pusan incline to prefer rich space, those of Kwangju imposing space and those of Cheonan casual one.

This study was to examine music preferences of school-aged cochlear implant(CI) recipients in comparison with normal hearing(NH) children. Participants were 12 CI recipients and 155 NH children. CI children were recruited from a hospital in Seoul and they had cochlear implants for longer than two years(M = 4.7). NH children were randomly sampled. All participants were asked to respond to a questionnaire and rate their music preferences. The results showed that while 58.33% of CI recipients preferred child voices, 71.61% of NH children preferred adult voices. For preferred frequency range, both of CI and NH groups preferred higher frequency. With regard to preferred musical styles, while CI children gave the highest rating(M = 3.58) to Korean folk songs on the 5-point Likert scale, popular music and TV and soundtrack music were found to be the highest-rated styles(M = 3.83) for NH children. These results indicate that self-rated music preferences of CI recipients may be affected by a musical environment that these children have experienced. The results also implies that the provision of appropriate musical input and experiences would significantly affect future music preferences and appreciation of CI children. Providing useful information about music preferences of CI recipients in comparison with NH children, this study has significant implications for further studies on this population.

본 논문에서는 1) 지금까지 이루어진 광장선호연구를 토대로 광장 설계시 이용될 수 있는 12가지 설계지침을 제시하며, 2) 광장선호를 진화 이론의 틀에서 분석한 사례연구를 소개하고 있다. 12가지 광장설계지침은 1970년부터 지금까지 이루어진 광장형태연구들로부터 제시되었으며, 광장 의 위치, 규모, 시각적 특질, 활동, 미기후, 경계설계, 부공간설계, 동선설계, 식재설계, 휴식공간설계, 음식, 조형물설계 등에 관련한 고려사항을 포함한 다. 광장선호를 진화이론에서 분석한 사례연구는 Appleton의 조망과 은신 이론(prospect and refuge theory)을 분석의 틀로 이용하며, 3개 광장에서 의 이용행태 관찰을 바탕으로 한다. 구체적으로 각 광장의 앉는 장소 (sitting area)가 가지고 있는 조망(prospect) 특성과 은신(refuge)특성을 분석하고 이러한 특성들이 사람들의 선택선호도(앉는 장소로서의)와 관련 성이 있는가를 살펴보고 있다. 연구결과를 보면 광장의 성격이 완전히 공 공적(public)일 경우만이 전반적인 선호행태가 조망(prospect)과 은신 (refuge) 특질과 관련되고 반공공적(semi-public)이나 사적(private)일 경우 에는 Appleton의 이론으로 선호행태 설명이 불가능함을 알 수 있다.

The success of a product is only possible on the basis of user preference for products and the user preference for products is greatly influenced by the design. Designers have to understand user preference and convert it into the combination of specified design attribute, and after that they should design products which have the image that they want to get. Then the product will be sure to be a hit. Therefore, on the point of view of design, it is necessary to find oui definitely the consumer preference frame : the relationship among design preference - design images - design attribute. This study will give you guidelines on which designers can select and design some more objective and reliable design factors, finding out the relation of cause and effect by which they can know what kind of product designs their consumers like and how the popular image which that products offer is composed of. Therefore, in this study, after we developed the consumer response framework which is proposed by Bloch(1995) : distinct relationship model among preference - design image adjective - design factors, we analyzed the relationship among preference-design image adjective - design factors through the empirical researches. And then we give the way of design.

This study examines the effect of Korean Wave recognition on the preference of cheese chicken ribs in Vietnamese students. It also examines the effect of preference of cheese chicken ribs on the Korean food image of Vietnamese students and their intention to visit Korean restaurants. We analyze the results and try to help globalization of Korean food, development of Korean menu and marketing activities. As a result of the analysis, the hypothesis that the recognition of Korean Wave has positive (+) influence on the preference of cheese chicken ribs was not adopted. The recognition of Hallyu influenced the preference of cheese chicken ribs through SNS influence. SNS influence was found to be a mediator between Korean recognition and cheese chicken rib preference. In case of foreigners, they will recognize Korean Wave through various instruments. Based on the results of this study, it is necessary to study various factors that affect the preference of Korean food and the preference of single menu, and to re - examine Korean food which can globalize Korean food.

This study is a study on the factors of preference for mobile game characters whose intellectual property rights (IP) influence is great. There have been many cases in which user-side research has been conducted on the character's preference factors. However, it is largely macro-divided. Detailed analytical studies are needed because details are overlooked. By classifying the elements of the character, the five-point scale of the recorder also obtains the data through the survey. Detailed factors were analyzed according to the results. Prior studies and results were compared and factors consistent with prior studies were analyzed. Because this study analyzed detailed factors, unlike previous studies of macro view. It is expected to help develop characters in the future.

선호구조의 논리를 결정모델에 적용시킬 때 선호구조는 일반적으로 특정 수치적 순서화 조건을 만족하게끔 표현된다. 그래야 주어진 선택지들을 둘러싼 개인 혹은 집단의 선호구조에 관한 정보가 형식적으로 표출될 수 있다고 여겨져 왔다. 그러나 선호구조의 수치적 순서화에 의해서만 선호관계의 정보가 형식적으로 표출될 수 있다는 성각은 일종의 독단이다. 더욱이 다양한 선택지의 결합에 의한 선호구조의 정보 이동은 기존의 수치적 순서화 속에서 제대로 다루어질 수 없다. 하나의 대안으로서 선형대수의 그래프이론에 바탕을 둔 선호구조의 질적 순서화 방식을 제안한다. 개인 혹은 집단의 선호구조에 관한 정보는 제안될 질적 순서화에 의해 보다 포괄적으로 다루어질 수 있다.

The researcher analyzes the relationship between the number of neighbors and the prediction accuracy in the preference prediction process using collaborative filtering system. The number of neighbors who are involved in the preference prediction process are divided into four groups. Each group shows a little difference in the preference prediction. By using prediction error averages in each group, linear functions are suggested. Through the result of this study, the accuracy of preference prediction can be raised when using linear functions by using the number of neighbors in the suggested system.

위치기반서비스(LBS)는 사용자의 위치를 기반으로 다양한 정보제공 서비스를 하고 있다. 최근 연구에서는 단순한 정보제공이 아닌 사용자의 상황인식(Context-Aware)을 통하여 사용자에게 적합한 정보를 제공해주는 지능화된 서비스를 제공하고 있다. 하지만 현재 연구들은 사용자의 기본정보와 선호도정보를 이용한 단일기준 추론을 통하여 사용자에게 정보를 제공해주고 있으며, 이것은 사용자의 다양한 기준의 의사결정을 반영하지 못하는 한계점이 있다. 이러한 한계점을 극복하기 위하여 본 연구에서는 사용자의 정보, 선호도, 공간지리선호도 정보 Ontology를 구축하고, 의사 결정 기준에 가중치를 부여하는 Cost Value Ontology를 구축하여, 다 기준 의사추론을 통해 사용자에게 적절한 추천 결과가 도출되는 Ontology 추론시스템을 제안한다. 사용자들의 개인적인 특성 지식과 공간지리 선호도 지식을 구축할 수 있으며, 이러한 특성으로 구축된 지식 기반 하에 입력된 사용자 정보와 추론을 통하여 이 시스템을 통해 사용자의 선호도 Ontology를 구축할 수 있으며 이를 이용한 추론을 통하여 사용자의 현재상황에 적합한 결과를 도출함을 보였다.
