A Context-based Multi-Agent System for Enacting Virtual Enterprises
Lee, Kyung-Huy ; Kim, Duk-Hyun ;
The Journal of Society for e-Business Studies, volume 12, issue 3, 2007, Pages 1~17
A virtual enterprise (VE) can be mapped into a multi-agent system (MAS) that consists of various agents with specific role(s), communicating with each other to accomplish common goal(s). However, a MAS for enacting VE requires more advanced mechanism such as context that can guarantee autonomy and dynamism of VE members considering heterogeneity and complex structure of them. This paper is to suggest a context-based MAS as a platform for constructing and managing virtual enterprises. In the Context-based MAS a VE is a collection of Actor, Interaction (among Actors), Actor Context, and Interaction Context. It can raise the speed and correctness of decision-making and operation of VE enactment using context, i.e., information about the situation (e.g., goal, role, task, time, location, media) of Actors and Interactions, as well as simple data of their properties. The Context-based MAS for VE we proposed('VECoM') may consists of Context Ontology, Context Model, Context Analyzer, and Context Reasoner. The suggested approach and system is validated through an example where a VE tries to find a partner that could join co-development of new technology.

Kim, Sun-Ho ; Kim, Jin-Yong ; Park, Jeong-Jae ; Song, Ju-Hyung ; Kim, Hyun-Min ; Ann, Chong-Hwan ;
The Journal of Society for e-Business Studies, volume 12, issue 3, 2007, Pages 19~31
In this research, we propose the operational method of the RFID-based NPI (National Product Identifier) which can manage product assets for the Korean government in the future. First of all, we present the operational concept of the national product asset management. Second, we suggest the structure of the NPI which accommodates ISO/IEC 15459 and the method to encode NPI and related data to ISO/IEC 18000-6C tags. Finally, we propose the operational business processes to generate and manage NPI in the stages of product procurement and product asset management.
Feature-Oriented Requirements Change Management with Value Analysis
Ahn, Sang-Im ; Chong, Ki-Won ;
The Journal of Society for e-Business Studies, volume 12, issue 3, 2007, Pages 33~47
The requirements have been changed during development progresses, since it is impossible to define all of software requirements. These requirements change leads to mistakes because the developers cannot completely understand the software's structure and behavior, or they cannot discover all parts affected by a change. Requirement changes have to be managed and assessed to ensure that they are feasible, make economic sense and contribute to the business needs of the customer organization. We propose a feature-oriented requirements change management method to manage requirements change with value analysis and feature-oriented traceability links including intermediate catalysis using features. Our approach offers two contributions to the study of requirements change: (1) We define requirements change tree to make user requirements change request generalize by feature level. (2) We provide overall process such as change request normalization, change impact analysis, solution dealing with change request, change request implementation, change request evaluation. In addition, we especially present the results of a case study which is carried out in asset management portal system in details.

The Journal of Society for e-Business Studies, volume 12, issue 3, 2007, Pages 49~74
As increasing IT investments in corporate decision makers' locus move from application level to organizational level. However, many companies still don't have a structured IT decision makings architecture. According to existing IT governance research, although companies are included in similar environment, size, and industry they have a variety of IT governance modes because of not single contingency factor but multiple contingencies factors. The goal of this study is to suggest key IT activities and contingency factors which affect IT decision makings architecture based on existing IT governance studies, to develop an IT governance research model with multiple contingencies theory, and to articulate IT governance architectures of small or medium sized companies in Korea. Through extracting a desirable IT governance framework, our research is going to help to increase companies' value.

Joo, Jae-Hun ; Yim, Jae-Geol ;
The Journal of Society for e-Business Studies, volume 12, issue 3, 2007, Pages 75~93
This paper presents real-time online early fire warning systems developed for preserving cultural properties of Bulguksa which is a world heritage designated by UNESCO. The system is based on the ubiquitous sensor network employing 900MHz and 2.4GHz bands. In this paper, we analyze requirements that should be considered in building effective management systems of cultural heritages by using wireless sensor network. Finally, we introduce the architecture, sensor and network design, and software design of the fire warning systems which is an initial version of U-Bulguksa. The current version of systems has been operating in Bukguksa for a few months. U-Bukguksa project sponsored by National Information Society Agency is ultimately aimed at developing an integrated system of U-cultural heritage management and U-tourism. The former aims to conserve and manage intangible cultural properties by providing a variety of environmental information such as erosion, crack, and gradient as well as fire which are important causes of loss and damage in real-time and online. The latter refers to the intelligent tourism information and guidance systems allowing tourists to get the personalized content on cultural heritages and help guidance with mobile devices in Bulguksa.

Tark, Moon-Hee ; Kim, Kyung-Hwa ; Shim, Jun-Ho ;
The Journal of Society for e-Business Studies, volume 12, issue 3, 2007, Pages 97~106
A core technology that may realize the Semantic Web is Ontology. The OWL (Web Ontology Language) has been positioned as a standard language. It requires technical expertise to directly represent the domain knowledge in OWL. Based on our experience of analyzing the fundamental relationships of concepts in e-catalog domain, we have developed a visual product information modeler called PROMOD. The modeling editor makes it possible to automatically generate the OWL codes for the given product information. We employ an Extended Entity-Relationship for conceptual modeling, enriched with modeling elements specialized for the product domain. In this paper, we present our translation schemes from EER model to OWL codes, and how to design and implement the modeling editor. We also provide a scenario to demonstrate the usage of the editor in practice.

Ko, Il-Sang ; Choi, Su-Jeong ; Kim, Jeong-Hee ;
The Journal of Society for e-Business Studies, volume 12, issue 3, 2007, Pages 107~131
Due to an increase of the importance of E-catalogue on electronic commerce, E-catalogue systems have been prevailing for their production and efficient management around Web environment. In this study, we categorize service factors off-catalogue systems into three aspects contents-providing, user participation, and system management, and we measure their impacts on user satisfaction. The results of the study show that richness, design, trust, interaction, function of transaction management, system extensibility, system stability, and security have been found out to be significant factors to affect user satisfaction.
Trend Analysis Service using a Temporal Web Ontology Language in News Domains
Kim, Sang-Kyun ; Lee, Kyu-Chul ;
The Journal of Society for e-Business Studies, volume 12, issue 3, 2007, Pages 133~150
In this paper we investigate a trend analysis service using Semantic Web technology in a news domain. The trend analysis service can provide more intelligent answers rather than the answer given In current news search engines since it can analyze the passage of time and the relation among news. In order to provide the trend analysis service, the capability of temporal reasoning is required, but the Semantic Web language such as OWL does not support the reasoning capability. Therefore, we propose a language TL-OWL(Temporal Web Ontology Language) extending OWL with the temporal reasoning.
Ontology describing Process Information for Web Services Discovery
Yu, Jeong-Youn ; Lee, Kyu-Chul ;
The Journal of Society for e-Business Studies, volume 12, issue 3, 2007, Pages 151~175
Until now, most semantic web service discovery research has been carried out using either Web Service Modeling Ontology (WSMO) or a profile of OWL-based Web Service ontology (OWL-S). However, such efforts have focused primarily on service name and input/output ontology. Thus, the internal information of a service has not been utilized, and queries regarding internal information such as 'Find book-selling services allowing payment after delivery' are not addressed. This study outlines the development of TM-S (Topic Maps for Service) ontology and TMS-QL (TM-S Query Language), two novel technologies that address the aforementioned issues in semantic web service discovery research. TM-S ontology describes the behavior of services using process information and consists of three sub-ontologies: process signature ontology, process structure ontology and process concept ontology. TMS-QL allows users to describe service discovery requests.

The Journal of Society for e-Business Studies, volume 12, issue 3, 2007, Pages 177~191
Supplier relationship management (SRM) is an important contributor to a company's efficiency and credibility. Although several ways are used to provide SRM functionality, these are often not easily integrated with existing procurement systems. We designed and implemented a practical SRM system called BestChoice SRM and present its design and architecture. It has the core functionality of SRM with the simple adaptability of BestChoice which is a decision support system for evaluating suppliers with the aid of visualized analysis It allows seamless integration with existing systems and permits flexible strategy changes as market conditions shift. The key to this flexibility is template-based segmentation. Ease of integration was demonstrated through the installation of BestChoice SRM at a major Korean commercial e-procurement agency.
Implementation of an User-guided Classification Tailoring System
Jang, Du-Seok ; Chun, Jong-Hoon ;
The Journal of Society for e-Business Studies, volume 12, issue 3, 2007, Pages 193~210
In order for a classification system to be useful in every day business environments, it has to reflect peculiar characteristics of enterprises and organizations. By automating the generation process of classification, the overall operation of classification system becomes effective and efficient. However, in order for it to be really useful, human input and interventions are needed from the very beginning phase of the classification generation. This paper proposes an user-guided classification generation algorithm, in which the user inputs a specific level of the classification that she/he wants. Also we propose and implement manipulation operators to tailor the initial classification into the shape that user wants.
A Technique of Replacing XML Semantic Cache

The Journal of Society for e-Business Studies, volume 12, issue 3, 2007, Pages 211~234
In e-business, XML is a major format of data and it is essential to efficiently process queries against XML data. XML query caching has received much attention for query performance improvement. In employing XML query caching, some efficient technique of cache replacement is required. The previous techniques considered as a replacement unit either the whole query result or the path in the query result. The former is simple to employ but it is not efficient whereas the latter is more efficient and yet the size difference among the potential victims is large, and thus, efficiency of caching would be limited. In this paper, we propose a new technique where the element in the query result is are placement unit to overcome the limitations of the previous techniques. The proposed technique could enhance the cache efficiency to a great extent because it would not pick a victim whose size is too large to store a new cached item, the variance in the size of victims would be small, and the unused space of the cache storage would be small. A technique of XML semantic cache replacement is presented which is based on the replacement function that takes into account cache hit ratio, last access time, fetch time, size of XML semantic region, size of element in XML semantic region, etc. We implemented a prototype XML semantic cache system that employs the proposed technique, and conducted a detailed set of experiments over a LAN environment. The experimental results showed that our proposed technique outperformed the previous ones.

Lee, Seung-Jin ; Wu, Chi-Su ; Lee, Hyung-Won ;
The Journal of Society for e-Business Studies, volume 12, issue 3, 2007, Pages 235~249
Workflow systems are software systems that control the execution of long-term processes. Members of an organization are in charge of executing processes. A work assignment policy, i.e who should perform a certain piece of process, has to be modeled and implemented in workflow systems. Organizations may have a large variety of problems in work assignment, and it may not be feasible to devise a single model to cover all problems. In this paper, we introduce generality to work assignment design problems in workflow systems We provide a meta-model based approach which enables us to define arbitrary problem oriented work assignment policies.

Mun, Hyeon-Jeong ; Sung, Jung-Hwan ; Kim, Young-Ji ; Woo, Yong-Tae ;
The Journal of Society for e-Business Studies, volume 12, issue 3, 2007, Pages 251~268
We design and implement an efficient storage technique to improve query processing for a large RDF data set. The proposed techniques can minimize data redundancy compared to the existing techniques by splitting relation information and data information from triple formatted RDF data. Also, we can enhance query processing speed separating and connecting the entire query steps by relation and data based on the proposed storage technique. The proposed technique can be applied to the areas, such as e-Commerce, semantic web, and KMS to store and retrieve a large RDF data set.

Mun, Hyeon-Jeong ; Lee, Soo-Jin ; Kim, Young-Ji ; Woo, Yong-Tae ;
The Journal of Society for e-Business Studies, volume 12, issue 3, 2007, Pages 269~282
We propose a personalized concept-based retrieval technique that uses domain ontology. Proposed system consist or representative concept extraction, user profile construction, and concept-based retrieval stages. First, we extract representative concept with using technique form contents and create the domain ontology. We compose user profile analysis that uses domain ontology for personalized concept-based retrieval. To verify the efficiency of the proposed technique, we perform experiment for Internet site in the engineering area. The results of experiment show that the proposed technique using the domain ontology and user profiles is more efficient than the existing techniques. Hence, the proposed concept-based retrieval technique can be expected to contribute to the development of an efficient personalized recommendation system or e-Commerce system.
