Ontoeng:A Design Method For Ontology Engineering In Information Systems, Mutaz M. Al-Debei, Guy Fitzgerald Jan 2009

Ontoeng:A Design Method For Ontology Engineering In Information Systems, Mutaz M. Al-Debei, Guy Fitzgerald

Dr. Mutaz M. Al-Debei

This paper addresses the design problem relating to ontology engineering in the discipline of information systems. Ontology engineering is a realm that covers issues related to ontology development and use throughout its life span. Nowadays, ontology as a new innovation promises to improve the design, semantic integration, and utilization of information systems. Ontologies are the backbone of knowledge-based systems. In addition, they establish sharable and reusable common understanding of specific domains amongst people, information systems, and software agents. Notwithstanding, the ontology engineering literature does not provide adequate guidance on how to build, evaluate, and maintain ontologies. On the basis of …

Formal Verification Of Urban Traffic System Using The Concept Of Fuzzy Workflow Simulation, Manuj Darbari, Abhay Kumar Srivastava, Sanjay Medhavi Jan 2009

Formal Verification Of Urban Traffic System Using The Concept Of Fuzzy Workflow Simulation, Manuj Darbari, Abhay Kumar Srivastava, Sanjay Medhavi

Journal of International Technology and Information Management

Modeling complex urban traffic system requires extensive use of workflow methodologies which can simulate almost real time traffic situations. Number of studies were done in the field of Urban Traffic Simulation like PLOTS, NETSIM and PALAMICS but none of them could provide a real formal solution. Our paper proposes a methodology using Fuzzy Petri nets for modeling real time traffic system. Fuzzy Petrinets are also visualised and tested by using Flow- Charter and HPSIM software packages. These packages help in providing successive iterations of process model for further refinement.

Egypt's Information Society Strategy: A Critical Lexicography, Neil Mcbride, Bernd Carsten Stahl Jan 2009

Egypt's Information Society Strategy: A Critical Lexicography, Neil Mcbride, Bernd Carsten Stahl

Journal of International Technology and Information Management

The development of ICT policies within developing countries in the past ten years has opened up a new area for study. These documents chart the ambitions of the countries for the use of ICT to promote rapid development. As such they are intercultural documents, developing at the interface between the culture of the country and western economic culture. This paper develops a critical approach to understanding these documents and studying their message. The approach involves the preparation of a critical dictionary which identifies relevant terms within the ICT policy document and reflects on their multiple meanings. The approach was applied …

Usability Investigation Of E-Business Web-Based Forms, Gerald V. Post, Albert Kagan, Betsy Page Sigman Jan 2009

Usability Investigation Of E-Business Web-Based Forms, Gerald V. Post, Albert Kagan, Betsy Page Sigman

Journal of International Technology and Information Management

Usability on Web sites is critical because almost no training is provided for users on commercial sites. Instead, Web design relies on standards and consistency across sites. Traditional usability results indicated that computer forms should follow paper-based forms. Yet, Web paradigms have evolved that are quite different from paper-based forms. Specifically, this study reveals that users commit fewer errors and prefer simple forms limited to a single concept per screen. This conclusion significantly alters the recommendations for designing business forms.

Supporting The Virtual Community: Social Bookmarking As A User- Based Classification Scheme In A Knowledge Library, Nicole Lytle, Tony Coulsom Jan 2009

Supporting The Virtual Community: Social Bookmarking As A User- Based Classification Scheme In A Knowledge Library, Nicole Lytle, Tony Coulsom

Journal of International Technology and Information Management

Knowledge libraries hold the promise of widespread access to information available anywhere, anytime, freeing patrons from the geographical and temporal boundaries that currently exist. The classification of materials and subsequent searching of knowledge library content is an overall problem with many complex parts. Relevant classification is important for optimal information retrieval. This is especially important for the virtual communities that exist with extended organizations. Rooted in the virtual community and digital library literature, this paper develops a theory for improving the information classification and retrieval process of knowledge libraries that support virtual communities by applying social bookmarking techniques.

Rapid Development Of Multimedia Instructional Modules For Information Technology Education, Nanda Ganesan Jan 2009

Rapid Development Of Multimedia Instructional Modules For Information Technology Education, Nanda Ganesan

Journal of International Technology and Information Management

A multifaceted learning model was developed for implementing e-learning in a largely commuter campus. The primary objective of the model was to build a flexible learning environment that combined the learning effectiveness of in-class learning with the flexibility and accessibility of online learning. One of the components of the model was the multimedia instructional modules produced to teach various Information Technology courses. Several different types of modules were produced representing chalk-and-talk type of lectures, PowerPoint presentations and software tutorials. The chalk-and-talk type of lecture modules and the software tutorials that emulated the in-class learning experience contributed positively towards enhancing the …

Can Information Systems Foster Emotional Intelligence? A Design Theory-Based Approach, Richard J. Burkhard, Thomas A. Horan, Brian N. Hilton, Michael Leih Jan 2009

Can Information Systems Foster Emotional Intelligence? A Design Theory-Based Approach, Richard J. Burkhard, Thomas A. Horan, Brian N. Hilton, Michael Leih

Journal of International Technology and Information Management

Researchers in Information Systems (IS) have conducted extensive research into various kinds of collaboration systems over the last twenty-five years. A parallel stream of inquiry in psychology and management has developed research in organizational Emotional Intelligence, which contributes to the effectiveness of group interactions by increasing cooperation and reducing conflict. Collaboration systems present a special opportunity to introduce soft management functions such as Emotional Intelligence because they are designed as an intelligent channel of interaction between group members. This research used an Information Systems Design Theory approach to guide the integration of Emotional Intelligence functions into collaboration systems. Two artifact …

Business Risks: When Is Fails To Detect Circumvention Activities, Stanley X. Lewis Jr., J. Scott Magruder, Eddy J. Burks, Carl Smolinski Jan 2009

Business Risks: When Is Fails To Detect Circumvention Activities, Stanley X. Lewis Jr., J. Scott Magruder, Eddy J. Burks, Carl Smolinski

Journal of International Technology and Information Management

A business must recognize and address various risk factors when establishing and maintaining its information system. The overall risk to management is that the control environment does not protect proprietary business data and the financial reporting system that produces financial statements and other information used by investors, creditors and regulatory agencies. These risks require that management implement efforts to ensure the integrity and effectiveness of control procedures over business activities while being aware of additional system issues such as failing to adequately consider other risks which are more business-oriented including the risk of failing to prevent or detect fraudulent or …

Learning And Forgetting In Maintenance Outsourcing, Hakan Tarakci, Sunantha Teyarachakul, Kwei Tang Dec 2008

Learning And Forgetting In Maintenance Outsourcing, Hakan Tarakci, Sunantha Teyarachakul, Kwei Tang

Hakan Tarakci

We study the effects of learning and forgetting on maintenance outsourcing in this paper. This is an extension of the paper by Tarakci et al. (2009), which analyzed the effects of learning on maintenance outsourcing. In our model, a manufacturer offers a short-term outsourcing contract, where payment includes a fixed value along with cost subsidization for each preventive maintenance activity, to an external contractor. The contractor schedules and performs preventive maintenance activities as well as repairs the system if there is a failure. We consider two types of learning: natural learning and learning by costly efforts. We then analyze the …

On The Problem Of Production Deadline And Maintenance Outsourcing, Sharafali Moosa, Hakan Tarakci Dec 2008

On The Problem Of Production Deadline And Maintenance Outsourcing, Sharafali Moosa, Hakan Tarakci

Hakan Tarakci

In this paper we consider a production-maintenance problem in which a buyer and a supplier have already entered into a contractual relationship for a firm delivery date. Our focus is on the production-related decisions of the supplier rather than the nature of the contract itself. We assume that production rate is actually constant as long as the system is up and running but randomness arises in production due to downtimes as a result of unpredictable failures (breakdowns) and scheduled preventive maintenance activities. Production maintenance is outsourced. As production output is random due to unreliable production facilities, the supplier needs to …

The Convergence In Workers’ Skill Levels Under Learning And Forgetting: The Fixed-Point-Property Approach, Sunantha Teyarachakul, Dogan Comez, Hakan Tarakci Dec 2008

The Convergence In Workers’ Skill Levels Under Learning And Forgetting: The Fixed-Point-Property Approach, Sunantha Teyarachakul, Dogan Comez, Hakan Tarakci

Hakan Tarakci

This paper presents a study on the convergence of workers’ skill levels under learning and forgetting in processing time in a batch-manufacturing environment. The convergence properties are examined under assumptions of an infinite horizon, a constant demand rate, and a fixed lot size. Our work extends the convergence results of Teyarachakul, Chand, and Ward (2008) beyond Globerson and Levin’s (1987) exponential forgetting function and Wright’s (1936) learning curve to more general classes of learning and forgetting functions. We also discuss why early papers other than Teyarachakul, Chand, and Ward (2008) did not find other types of long-term behaviors beyond convergence …
