대학도서관은 유학생들이 학습 자원을 얻는 가장 주요한 정보원에 속하므로 유학생들의 학업에 미치는 영향이 크다. 그러나 현재 대다수의 대학도서관은 영어를 제외한 다국어 지원 서비스를 적절히 제공하지 않기 때문에 영어가 모국어가 아닌 유학생들의 학업 수행을 어렵게 만들 수 있다. 따라서 본 연구는 대학도서관 서비스 중 다국어로 제공할 수 있는 서비스를 유학생 맞춤형 서비스로 정의하고, 이러한 맞춤형 서비스가 대학도서관 이용자 만족도에 미치는 영향을 살펴보고자 하였다. 더 나아가서, 본 연구는 유학생 맞춤형 서비스를 적절히 제공하고 있는 대학도서관의 유학생들과 그렇지 않은 대학도서관의 유학생들의 이용자 만족도를 비교하였다. 이를 위해 서로 다른 두 대학에 재학 중인 중국인 유학생을 대상으로 설문 조사하여 총 138부의 응답을 분석하였다. 본 연구는 유학생 맞춤형 서비스가 유학생의 대학도서관 이용 만족도에 영향을 미친다는 것을 발견하였다. 특히, 다국어 서비스의 지원은 안내 책자/표지판, 홈페이지를 통한 자료 접근 및 이용, 그리고 이용자 교육 등과 같은 서비스에 대한 만족도에 긍정적인 영향을 주었다. 본 연구의 결과는 대학도서관이 유학생들의 학업 활동을 효과적으로 지원하는 서비스에 대한 실질적 함의를 시사한다.

Web usage mining is a research field for searching potentially useful and valuable information from web log file. Web log file is a simple list of pages that users refer. Therefore, it is not easy to analyze user's current interest field from web log file. This paper presents web usage mining method for finding users' current interest based on fuzzy categories. We consider not only how many times a user visits pages but also when he visits. We describe a user's current interest with a fuzzy interest degree to categories. Based on fuzzy categories and fuzzy interest degrees, we also propose a method to cluster users according to their interests for user modeling. For user clustering, we define a category vector space. Experiments show that our method properly reflects the time factor of users' web visiting as well as the users' visit number.

With the increase in amount of data and information available on the web, there have been high demands on personalized information retrieval services to provide context-aware services for the web users. This paper proposes a novel dynamic multi-agent context-awareness user profile construction method based on ontology to incorporate concepts and properties to model the user profile. This method comprehensively considers the frequency and the specific of the concept in one document and its corresponding domain ontology to construct the user profile, based on which, a fuzzy c-means clustering method is adopted to cluster the user's interest domain, and a dynamic update policy is adopted to continuously consider the change of the users' interest. The simulation result shows that along with the gradual perfection of the our user profile, our proposed system is better than traditional semantic based retrieval system in terms of the Recall Ratio and Precision Ratio.

Recently, the study of smart phone user habits has become a highly focused topic due to the rapid growth of the smart phone market. Indeed, sequential pattern analysis methods were efficiently used for web-based user habit mining long time ago. However, by means of simulations, it has been observed that these methods might fail for smart phone-based user habit mining. In this paper, we propose a novel approach that leads to a considerably increased performance of the traditional sequential pattern analysis methods by reasonably cutting off each chronological sequence of user logs on a device into shorter ones, which represent the sequential user activities in various periods of a day.

User review sites are spaces where users can freely post and share their opinions, which are trusted by many people and directly influence sales. In addition, they overcome the limitations arising from existing requirements collection and are able to gather the needs of large numbers of different people at a low cost. Therefore, such sites are attracting attention as new spaces for understanding user needs. In a previous study, a user review analysis was attempted using 5W and 1H, and we inferred that a sentence containing "when" has special information based on the user experience. In addition, the requirements of the derivative activities in a user review can identify more user needs than the general requirements of derivative activities. In this paper, we propose a systematic method of deriving "when" sentences contain meaningful information from user reviews and converting them into use cases, which is one of the requirements of a specification method. This method converts unstructured data into structured data such that it can be included as the user requirements during software development from user comments expressed in natural language. This method will reduce project failures and increase the likelihood of success by enabling an efficient collection and analysis of user needs from valuable user reviews.

Recently, the importance of user experience (UX) has been rapidly increasing. Its utilization is emphasized for development of systems, products, and services. User experience is widely used across industries including services, products, processes, society, and culture. Therefore, if it is unsatisfactory, it is likely to have a direct negative impact on the corresponding system, product, or service. The failure to analyze user experience causes significant damage to the project, which may lead to its failure or redevelopment; it is hence necessary to prioritize the verification of UX in the earliest stages of development. The requirements development stage, which is a preceding stage, is an appropriate stage for the verification of user experience because the identification of user needs is completed and prototypes can be implemented. In this paper, we proposed a systematic requirements development stage; it adds user experience verification activities to the requirements development stage, using the Honeycomb model, which is a widely used tool for verifying the overall UX. User experience verification was added to the existing requirements development activities, which consisted of three steps: model definition and requirements placement, discussions between external and internal stakeholders, and review by internal stakeholders. By easily validating the user experience through this systematic requirements development stage, we expect to minimize the damage to the project due to the failure of the user experience analysis and increase the possibility of success.
