Methodological Considerations in Building Business Ontologies for Decision Support

This paper tries to identify some methodological consideration in building business ontologies for decision support. We treat the problems that business domain poses for knowledge engineers. We also discuss the main semantic web technologies involved in developing ontologies. We consider also the problems that decision support presents for ontologies. From these considerations we identify and discuss some methodological aspects that building ontologies for business decision support must take into considerations

An Empirical Study on the Impacts of the Knowledge Sharing ntention on the Use of Knowledge Management Systems : The Comparable Analysis between Public and Private Sectors in the Maritime and Port

Abstract An Empirical Study on the Impacts of the Knowledge Sharing Intention on the Use of Knowledge Management Systems. - The Comparable Analysis between Public and Private Sectors in the Maritime and Port - Kim, ChulHyun Department of Shipping Management The Graduate School, Korea Maritime University (Directed by Professor Chang, MyungHee) Recently, the knowledge management has been applied extensively in public organizations for their competitiveness in rapidly changing environment. Otherwise the cognizance on necessity of the knowledge management and earlier studies are insufficient, although infrastructure or tools like groupware, intranet for constructing and operating the knowledge management systems are constructed in the maritime sectors. This study confirms factors for knowledge sharing intention in the whole, public and private sectors of maritime and port. And this paper reveals that how does knowledge sharing intention effect the use of the knowledge management systems by empirical analysis in the whole, public and private sectors of the maritime and port. Also, this study is to provide differential guidelines for organizations considering the introduction of the knowledge management systems and confirm the differences through the comparative study between public and private sector of maritime and port. The factors on the knowledge sharing intention as support of CEO, the sense of self-worth, the trust among colleagues, the trust towards executives and incentives and the use of knowledge management systems are assorted through the literature reviews. The survey were sent to each of these 4 organizations implementation of knowledge management systems, department of Ministry of Maritime Affairs & Fisheries, Korean Container Terminal Authority within public organizations and Hanjin shipping, Hyundai Merchant Marine within private corporations, with 320 responses retruned (89 percent response rate). The results through statistical analyses are as follows: First, the support of CEO was not valid statistically on the knowledge sharing intention and the use of knowledge management systems in the whole, public and private sector of maritime and port. The reason are as follows1) The results of the knowledge management systems did not exceed expectation to CEO in the maritime and port sectors. 2) The groupware could be a role as knowledge management systems in the field, the use of the knowledge management systems was not essential to knowledge workers in the maritime and port sectors. Second, the sense of self-worth effects the knowledge sharing intention in the whole, public and private sectors of maritime and port. Third, the trust among colleagues and the trust towards executives effect the knowledge sharing intention in the whole, public and private sectors of maritime and port. The trust among colleagues effect the knowledge sharing intention in the public and private sectors of maritime and port. However, the relation between the knowledge sharing intention and the trust towards executives is not valid statistically in the public and private sectors of maritime and port. The result that the trust between demanders and suppliers influences the knowledge sharing intention and also find out that the knowledge management systems is drawing for the knowledge sharing among colleagues in the maritime and port sector. Fourth, that the incentives are not valid statistically on the knowledge sharing intention and use of the knowledge management systems in the whole sectors of maritime and port. Because the knowledge management systems was introduced during short-term and the effective incentives for the knowledge management were not settled yet. In the comparative analysis between public and private sectors, the incentives effect the knowledge sharing intention in the private sector. This result shows that the efficient system for incentives is operated in private sectors more than public sectors. Finally, that the knowledge sharing intention effects the use of knowledge management system in the whole, public and private sectors of maritime and port. The result of this study would be applied as a basic idea to seek the plan of the promotion through the knowledge management systems for the future by addressing the problems on the use of the knowledge management systems to users in the maritime and port sectors. Also, this study suggests proper methods for introduction of the knowledge management systems to corporations preparing the systems by addressing influential factors for increasing use of the knowledge management systems in the maritime and port sectors.

Politics and public opinion in China: the impact of the Internet, 1993-2003

This dissertation is to provide empirical evidence as well as in-depth discussions to reflect the theme of new technologies like the Internet and its impact and implications on the political systems and public opinion in the Chinese context. It is the premise that technology can transform the mode of political communication and that this in turn can change the nature of political participation, as well as the milieu in which political discussions are made. This project concludes that the Internet has not at this stage fundamentally transformed China's political system, let alone caused a sudden political regime collapse and engendered a sweeping democratisation process. The Internet is, however, expanding people's minds, facilitating public discourse, and pushing for more transparent and accountable governance. In other words, the Chinese government is argued as not being as much in control of public debates on the Internet as it is of debates in other forms of media channels; the government cannot control and manipulate public opinion as much as it has traditionally done. This work has contributed to a more systematic picture of public opinion on political issues with documented examples, thanks to the Internet. Besides, this research has shed light on how to measure the impact of the Internet upon political debates, and to document the political impact of the Internet. Moreover, this dissertation highlights a usually neglected phenomenon that researching the political change or transformation in China can also be conducted form different aspects like the impact of Information Communication Technologies on its political system. The conventional approaches may be enriched thanks to the advent of new technologies in the increasingly networked, globalised and marketised world

Internet-based information and retrieval systems

Abstract There is limited reliability of internet-based information systems. For example, Internet search engines provide results that have limited reliability and data available on the Internet is limited in its reliability. As a result, the purpose of this paper is to elicit sources of the lack of reliability, develop a model that can be used to study the impact of reliability and propose some solutions to mitigate reliability issues. The model couches Internet data as an ''intermediary report.'' For example, use Ž . of a search engine will generate an intermediary ''report'' providing a list of relevant universal resource locators URL and a corresponding brief description that may or may not correctly describe the label being searched. This ''report'' structure is used to model Internet information and retrieval systems as an intermediate step between users of the system and the original or expected information. The basic model of information relevance in the information retrieval process is reviewed, where the precision is a function, in part, of the recall and fallout rate. Reliability is found to have an impact on precision and fallout rates. Alternatives are proposed to mitigate the impact of this lack of reliability.
