Kim, H., Lee, K., Kim, J., A Peer-to-Peer CF-Recommendation for Ubiquitous Environment, Lecture Notes in Computer Science 4088: 678-683, 2006.pdf

Abstract

In ubiquitous environment where all entities can freely connect and collaborate with each other from anywhere, the amount of accessible information is overwhelming and desired information often remains unfound. So there is a growing need to provide the personalized recommendation services for the customers in ubiquitous space. This paper suggests a UREC_P2P (U-Recommendation by peer-to-peer), a recommendation procedure in ubiquitous environment adopting P2P technologies combined with collaborative filtering algorithm. UREC_P2P is implemented and comparatively evaluated with a CFbased recommender system in client-server environment. The evaluation result shows that UREC_P2P has a good potential to be a preeminent and realistic solution to the recommendation problems encountered in ubiquitous environment.

Lee, K., Jeon, B., “Analysis of Best Practice Policy and Benchmarking Behavior for Government Knowledge Management,” Lecture Notes in Computer Science, pp. Vol. 3035, 70 – 79, May, 2004. – SCIE, ISSN:0302-9743. pdf

Abstract

Korean government has several best practice competition and diffusion programs for the purpose of public administration reform and the improvement of government service. From the perspective of knowledge management, this paper evaluates the best practice policy and analyzes the main factors influencing the recognition, adoption and utilization of best practices through the email-based survey and interview with local government officers. The result shows that 1) The government officers’ recognition of best practice programs and the best practices themselves is not high, 2) The adoption and utilization of a best practice is affected by its value and officer’s information needs, 3) Raising the recognition of Best practice policy affects the recognition and adoption of a best practice, and 4) The recognition and utilization of a best practice is affected by the work experience. The result gives important implications for designing and implementing government knowledge management systems and strategies.

Business Model and Governance of Policy Knowledge Service for Government Knowledge Management: A Case Study

Lee, K., “Business Model and Governance of Policy Knowledge Service for Government Knowledge Management: A Case Study,” Lecture Notes in Computer Science, Vol. 3035, 27-36, May, 2004. – SCIE, ISSN:0302-9743. pdf

Abstract

A national knowledge management system consists of internal knowledge management systems of governmental agencies and various knowledge services playing a role of intermediary, catalyst, and network. A policy knowledge service plays the roles of abstracting, codifying, and diffusing knowledge in public sector. Through abstraction and codification, it maximizes the proprietary value of knowledge. Through the diffusion of knowledge in proprietary form into public sphere, it maximizes the shared value of knowledge. In this paper, the business model and governance strategy of policy knowledge services are discussed thorough theoretical understanding and practical experience of operating Korea’s Knowledge Center for Public Administration and Policy. Three dimensions of policy knowledge services and two hypotheses on the governance of policy knowledge services are suggested.

Development of E-Government Service Model: Business Model Approach

Lee, K. Hong, J., “Development of E-Government Service Model: Business Model Approach,” International Review of Public Administration, vol. 7, no. 2, December, 2002.pdf

Abstract

Most discussions on electronic government have provided ad hoc guidelines. For a systematic framework for e-government service, this article adopts a business model approach and develops an e-government service model. Based on the analysis of business model researches and a comparison between e-business and e-government service, the paper defines and identifies the characteristics of the components of an e-government service model. These components are objectives, value proposition, service offering, activity configuration, and financial sustainability. Based on this framework, the authors perform a case analysis of the electronic services in the offices of the presidents of Korea and the U.S.A.

Abstract

 Previous U-Commerce researches have dealt with the business support systems for traditional commerce space such as real world shopping malls. This paper investigates U-Commerce business models in service space. The McDonald’s Touch-Order case is analyzed from business model perspective and the Media-Embedded Place business model is introduced as a UCommerce business model for value creation in service space. The mediaembedded place business model attaches autoidentification tags to tables or billboards, triggers commercial transaction through the tags, and shares the revenues and the incentives among the place owners and commerce/content providers. This paper analyzes its scenario and applications and illustrates the profitability analysis using socalled ‘tag evaluation model’.

Evaluation of Conversion Action Data Mechanisms in Cost-Per-Action Advertising

이첨, 이경전, Cost-Per-Action 광고 방법을 이용한 Conversion Action Data 메커니즘의 평가, Information Systems Review, 18(2):123-135, 2008.pdf (in Korean)

 

Abstract

The online advertising industry’s business model undertakes the change from CPM (cost-per-mille)-based to CPC(cost-per-click)-based. However, due to the problem of ‘Click Fraud’, CPA (cost-per-action) has been regarded as a new step. For CPA, publishers need to get information after a user clicks an advertisement. Therefore, in CPA, the key is to get Conversion Action Data (CAD). This paper introduces two existing mechanisms for getting CAD, compare their characteristics, and analyze their limitations. Then the two new mechanisms are introduced and their requirements and feasibility are analyzed. Lastly, we compare the existing two and the new two mechanisms, and point out each mechanism’s business possibility, value and Application Area. This paper will help publishers choose the most appropriate mechanism on the basis of their situation.

Design and Evaluation of U-Publication: Tag-Embedded Publication System and Business Model

박아름, 이경전, U-Publication 시스템과 비즈니스 모델의 설계와 분석, 지능정보연구, 14(3):41-57, 2008. ISSN 1229-4152.pdf (in Korean)

Abstract

 

U-Publication, the Tag-Embedded publication, is one of U-Media. U-Media is defined as a media where human creates and consumes content through not only human cognitive and perceptual processes but also through the interactions between surrounding digital systems. U-Media provides information by generating, collecting, and attaching the content itself and the related information based on the interaction of the bio-systems incorporating digital information and devices embedded in humans, and surrounding objects including external digital devices. Using U-Publication, readers consume its content not only in offline but also online through a mobile RFID reader which touches and connects the URLs embedded in the RFID tags attached to it. Readers can consume the additional content though the hyperlinks attached to U-Publication and perform commercial activity as well as consumer the printed content. This paper defines the RFID-Tagged publication, proposes its related business models, and evaluates the alternative business models through a simulation study.

Abstract

The aim of this research is to develop a new business model using mobile RFID in exhibition spaces such as museums and art galleries. Using mobile RFID, the exhibition space is expected to be evolved from a simple media space only for the exhibition to an extended space integrating media, commerce and entertainment. This paper proposes a u-Exhibition business model and its scenario in the u-Exhibition space. We discuss the real-world issues for the implementation and show the ways of investigating working conditions for the business model through revenue simulation and analyzing the expected value of tag installed on the exhibition space by so-called ‘tag evaluation model.’

윤은정, 이경전, UCC 지식 동영상 공유 서비스의 고객 모델 분석 사례, 지능정보연구, 제15(1):15-30, 2009. ISSN 1229-4152.pdf (in Korean)

Abstract

 

As knowledge is now being distributed and shared through the Internet not only in the form of text but also in that of video, UCC((User Created Content) knowledge video sharing services have emerged on the Internet such as Instructables.com. This paper deals with a UCC knowledge video service in real world and reports the case of analyzing its customer model. The knowledge video sharing service can be considered as both a kind of discontinuous innovation, which requires knowledge provider’s technical ability of creating and editing UCC video, and a value network, which matches UCC providers and consumers therefore brings network effect, we first adopt the Chasm theory as the base of the customer model and refine the customer model referencing the Technographics, which is also an Internet-refinement of the Chasm model. Finally, non-customer analysis of Blue Ocean strategy is applied for exploring potential customers of the service.
