Communications of the IIMA
In this paper, we present a new solution, in which the fuzziness of both subsequences and subsequences interval has been taken into consideration for solving the problem of multidimensional time series fuzzy association rules mining. Aimed at dealing with the new conception, this paper has put forward some key algorithms of the solution. Finally, an application example of multidimensional time series fuzzy association rules mining is illustrated. The result shows that rules with fuzzy interval can only be mined out by the above-mentioned new method.

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
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. Survey Of Entity Resolution And Record Linkage Methodologies, David Guy Brizan, Abdullah Uz Tansel
Communications of the IIMA
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. In …

While much has been studied and written about the adjustments managers must make when supervising remote workers in virtual work arrangements, little has been written about the potential change in the organizational culture and the effect the culture has on the virtual worker's quality of work life and professional isolation. Not only may culture affect the implementation and success of telecommuting arrangements, but the increased isolation and independence of a virtual worker may impact the culture surrounding remote workers and create an organizational subculture. This study examines the relationship between quality of work life, professional isolation, and an organization's cultural …

The internet and e-commerce technologies have already altered the way businesses operate. In the recent past, E-govemment has attempted to emulate the success of e-commerce organizations. This paper explores the status of e-govemment in metropolitan areas in Texas. The paper focuses on metropolitan areas since, based on reports on online usage in the US, rural areas still lag behind the metro areas. Consequently, rural counties, in general, have not developed their official e-govemment web sites as much as have counties in metropolitan areas.

On The Applicability Of Data Envelopment Analysis For Multiple Attriliute Decision Making In The Context Of Information Systems Appraisals, Edward W.N. Bernroider, Volker Stix

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 …

Union membership has undergone a dramatic decline and some have hailed the internet as a means for unions to reverse their membership declines. This study examines the usability of union websites. The content of union websites has been analyzed, but the usefulness of that content, and the overall usability of the websites, has not been assessed. In order for unions to fully utilize the internet and realize the potential benefits of cyberspace usage, they must provide websites that users find easy to use and that provide useful content. This study employs Hassan and Li's (2005) benchmarking approach in order to …

The establishment of an organizational help desk (HD) is to provide technical support to users when they encounter technical problems related to hardware, software and network connections. Due to the lack of resources, users often have to wait for a considerably long time before their enquiries and problems are answered and solved. This paper discusses the background of HD and its existing challenges. The application of Knowledge Management (KM) techniques and Knowledge Management System (KMS) enables HD to manage its knowledge effectively. In addition, the combination is capable of relieving the overloaded HD by shifting some of the troubleshooting responsibilities …

Web Usage Mining (WUM) integrates the techniques of two popular research fields - Data Mining and the Internet. By analyzing the potential rules hidden in web logs, WUM helps personalize the delivery of web content and improve web design, customer satisfaction and user navigation through pre-fetching and caching. This paper introduces two prevalent data mining algorithms - FPgrowth and PrefixSpan into WUM and they are applied in a real business case. Maximum Forward Path (MFP) is also used in the web usage mining model during sequential pattern mining along with PrefixSpan so as to reduce the interference of "false visit" …

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
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.
