Learning Without Default: A Study Of One-Class Classification And The Low-Default Portfolio Problem, Kenneth Kennedy, Brian Mac Namee, Sarah Jane Delany
Learning Without Default: A Study Of One-Class Classification And The Low-Default Portfolio Problem, Kenneth Kennedy, Brian Mac Namee, Sarah Jane Delany
Conference papers
This paper asks at what level of class imbalance one-class classifiers outperform two-class classifiers in credit scoring problems in which class imbalance, referred to as the low-default portfolio problem, is a serious issue. The question is answered by comparing the performance of a variety of one-class and two-class classifiers on a selection of credit scoring datasets as the class imbalance is manipulated. We also include random oversampling as this is one of the most common approaches to addressing class imbalance. This study analyses the suitability and performance of recognised two-class classifiers and one-class classifiers. Based on our study we conclude …
The Signing Of A Professional Athlete: Reducing Uncertainty With A Weighted Mean Hemimetric For Fuzzy Subsets, Julio Rojas-Mora, Jaime Gil-Lafuente
The Signing Of A Professional Athlete: Reducing Uncertainty With A Weighted Mean Hemimetric For Fuzzy Subsets, Julio Rojas-Mora, Jaime Gil-Lafuente
Julio Rojas-Mora
In this paper we present a tool to help reduce the uncertainty presented in the decision-making process associated to the selection and hiring of a professional athlete. A weighted mean hemimetric for fuzzy subsets with trapezoidal fuzzy numbers (TrFN) as their elements, allows to compare candidates to the “ideal” player that the technical body of a team believes should be hired.
Operational Knowledge Transfer In Municipal Utility Organizations, G. Christian Guvemator Iv
Operational Knowledge Transfer In Municipal Utility Organizations, G. Christian Guvemator Iv
Engineering Management & Systems Engineering Theses & Dissertations
Municipal water and wastewater utility systems experience several challenges related to maintaining an experienced operations workforce. One of these issues is the loss of operational knowledge as the current experienced workforce reaches the age of retirement. The future success of system operability depends upon a process that transfers the knowledge of the experienced employee into the organization before he or she retires. Recent investigations highlight the importance of, and the methods for, knowledge transfer; however, current literature does not include significant information on the municipal utility industry. The objective of this investigation is to identify how operational knowledge is being …

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 …
Qualitative Mapping For Understanding The Collective Judgment Building Process : A Study Of The Federal Open Market Committee, Hyunjung Kim
Qualitative Mapping For Understanding The Collective Judgment Building Process : A Study Of The Federal Open Market Committee, Hyunjung Kim
Legacy Theses & Dissertations (2009 - 2024)
This study develops a mapping method for studying a collective judgment building process in a decision-making group. Environmental uncertainties and a lack of information require a decision maker to make judgments about various issues relevant to the decision task. In a group setting, the members together weave their structural model of the system with available information to build a collective judgment for the decision task.

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
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 …

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

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.
