Naturalness Of Ontology Concepts For Rating Aspects Of The Semantic Web, Yoo Jung An, Kuo-Chuan Huang, James Geller
Naturalness Of Ontology Concepts For Rating Aspects Of The Semantic Web, Yoo Jung An, Kuo-Chuan Huang, James Geller
Communications of the IIMA
The Semantic Web is expected to be the next generation of the WWW. Ontologies and agents are major ingredients of the Semantic Web. In (Lee and Geller 2005), we have argued that some existing ontologies make use of unnatural concepts. We stated that unnatural concepts make it difficult to use an ontology and they contradict the purpose of an ontology, which includes explanatory power for the purpose of sharing information. In this paper we elaborate what makes a concept unnatural. We also analyze existing ontologies to get numeric measures of how natural their concepts are.
It Transformation Decision Processes: A Conceptual Framework For Efficiency/Effectiveness Optimization, Jurgen Reiner, Volker Stix
It Transformation Decision Processes: A Conceptual Framework For Efficiency/Effectiveness Optimization, Jurgen Reiner, Volker Stix
Communications of the IIMA
Decision processes are complex managerial challenges for long-term information technology (IT) initiatives with an organization-wide scope (in short: IT transformations). Costs, benefits, and risks of such IT investments are hard to capture, and the dozens ofprescriptive methods proposed for IT project evaluation have proved to contribute little to solve the dilemma in practice. Thus, as opposed to continue the search for another prescriptive evaluation methodology, this paper follows a new approach: it targets the development of a conceptual framework that allows for the improved management of holistic IT decision processes - as opposed to cook-book approaches that attempt optimizing the …

A great deal of research is focused on formation of a data warehouse. This is an important area of research as it could save many computation cycles and thus allow accurate information provided to the right people at the right time. Two considerations when forming a data warehouse are data cleansing (including entity resolution) and with schema integration (including record linkage). Uncleansed and fragmented data requires time to decipher and may lead to increased costs for an organization, so data cleansing and schema integration can save a great many (human) computation cycles and can lead to higher organizational efficiency.

Communications of the IIMA
This article elaborates on the applicability of basic and extended data envelopment analysis (DEA) models for various information system (IS) decision use-cases including illustrative examples from an enterprise resource planning (ERP) software investment appraisal. The usage of data envelopment analysis models and their extensions for IS decisions remains limited. This omission seems critical in particular for two reasons. First, organizational studies have shown that in practice business management fails to appreciate the portfolio of investment appraisal techniques available. Second, DEA based methodologies, especially new extensions, promise valuable insights to support the complex IS decision problem. The results indicate DEA applicability …

The rapid evolution of information technology over the past several decades has opened many new and unique modes of communication. Clearly, the web is one such technology. However, it is quite possible that a fascination with the technology per se can hinder participants from one of its main functions— effective communication. The following essay explores a return to the basics of designing an effective web-based communication strategy. The key components of this strategy are: 1) consistent look and feel, 2) conceptual consistency, and 3) positive attention.
Feasible Task Schedules With Minimum Project Cost Solved By A Genetic Algorithm, Michael L. Gargano, Louis V. Quintas
Feasible Task Schedules With Minimum Project Cost Solved By A Genetic Algorithm, Michael L. Gargano, Louis V. Quintas
Communications of the IIMA
Suppose that a project consists of n separate tasks and one and only one task can be completed in one time period. However, since some tasks can be started only before others have been completed, only feasible task schedules are considered. There is a cost associated with the time at which a task is completed and the project cost is equal to the sum of all the task costs. How can a feasible task schedule with minimum project cost be found for completing the entire project? This research proposes using a genetic algorithm to solve this problem efficiently.

Monitoring Sale Transactions For Illegal Activity, Robert J. Richardson
Communications of the IIMA
Discriminant analysis and neural network methodologies were applied to the problem of identifying illegal sales transactions. The researchers independently developed models using data provided by a cr^it card company. A series of measures were developed and used to construct the models. The final results were that the discriminant analysis model recognized 32.3% of the fraudulent activity, while the neural network approach found 28.9%. With only 11.6% of the transactions in common, the combination of the two models identified 49.6%i. In order to provide a real time monitoring program, the models were simplified yielding a capture rate of approximately 42%.

The Evolution Of An Internet Market Exchange And Value System: Examples From The Motion Control Industry, William Lightfoot, James Harris
Communications of the IIMA
This manuscript examines the evolution of internet value systems in the motion control industry. We believe the primary reason behind the inconsistent performance of that industry's adoption of the internet in the supply channel was largely due to poor strategy. Using a the concepts of bias exchanges and game theory it is suggested that intemet strategies such as disintermediation and first-mover advantage were elusive because firms focused too much on technology and not enough on customer value. Lessons for managers and future decisions are offered.
