Social media are widely used for online political discourse. Opinions shared on social media have different sentiments associated with them. Given the very high adoption rates of X (formerly known as Twitter) among adults, those who share their opinions on X not only represent a sizable segment of the society, but also influence (through emotion co...

Serious games developed for learning have gained popularity due to their promise for better learning outcomes. However, designing these games can be costly, take a long time, and may not lead to the desired outcomes if an adequate design process is not followed. Especially critical in this process is the creation of an effective game concept. Based...

An easily understood data warehouse model enables users to better identify and retrieve its data. It also makes it easier for users to suggest changes to its structure and content. Through an exploratory, empirical study, we compared the understandability of the star and traditional relational schemas. The results of our experiment contradict previ...

Individual and work characteristics are used in telecommuting plans; however, their impact on telecommuting success is not well known. We studied how employee tenure, work experience, communication skills, task interdependence, work output measurability, and task variety impact telecommuter productivity, performance, and satisfaction after taking i...

For almost two decades, the Internet and related technologies have made more information available to information users than they can handle. The decentralization of content creation that is a feature of Web 2.0 has only exacerbated this problem. This state of overload, combined with our tendency toward hypothesis-confirming behavior, can result in...

Many artificial intelligence tasks, such as automated question answering, reasoning, or heterogeneous database integration, involve verification of a semantic category (e.g. “coffee” is a drink, “red” is a color, while “steak” is not a drink and “big” is not a color). In this research, we explore completely automated on-the-fly verification of a me...

Earned Value Method (EVM) is a popular project control technique. In this paper, we discuss the extended version of EVM (EVM/LC) that addresses the effect of learning on the performance of project teams. These effects have so far been ignored in most EVM applications. We present a spreadsheet-based decision support tool that automates the calculati...

Building redundant capacity into an organization’s information technology (IT) infrastructure is a standard part of business continuity planning (BCP). Traditionally, cost concerns have dominated the decision of where to locate the redundant facilities. However; recently managers are becoming more aware of the fact that the very issues that make th...

Inefficient and ineffective search is widely recognized as a problem for businesses. The shortcomings of keyword searches have been elaborated upon by many authors, and many enhancements to keyword searches have been proposed.

The World Wide Web is a dominant global communication medium and knowledge repository. It is used by a great number of people with a variety of computer skills hence its usability is critical. As with many large information collections, the challenge with web usability is understanding the structure of a collection of information objects (web pages...

Effective e-mail management tools must treat messages as useful information, not simply as data congesting the network, the hard disk, or a user's inbox. Solutions that economize on scarce cognitive resources at the expense of the relatively cheap additional CPU power, disk capacity, or network bandwidth will ultimately prevail over those that purs...

We investigated whether a “context-aware” fisheye view can more successfully communicate the information contained in a set of process models (data flow diagrams) than a traditional “context-free” presentation. We conducted two controlled experiments: the first included a simple set of DFDs and tasks that required a basic understanding of the syste...

The increasing volume of electronic mail communication threatens to cause a state of “e-mail overload” where the volume of messages exceeds individuals' capacity to process them. To address this problem, this study extends the application of hierarchical clustering to the domain of e-mail. We report on the design and development of a system that ap...

The result of a typical web search is often overwhelming. It is very difficult to explore the textual listing of the resulting documents, which may be in the thousands. In order to improve the utility of the search experience, we explore presenting search results through clustering and a zoomable two-dimensional map (zoomable treemap). Furthermore,...

Testing of efficacy of the Fisheye-based DFD visualization using a preconfigured prototype, is discussed. The fisheye view technique is inspired by the nonlinear way in which people perceive their environments. From a managerial perspective, there are two important potential benefits of using fisheye views. First, the use of fisheye views can incre...

Information technologies have proliferated at an unprecedented rate to provide access to information across geographical boundaries. However, this proliferation has led to an information overload. Information overload has adverse impacts on information use and decision quality. This research focuses on the overload problem resulting from a web sear...

This study aims to predict the financial performance of publicly traded Turkish firms using their available financial data. Financial performance is measured by a firm's inclusion in an index of top performers, where the inclusion of firms is based on the value and sales volume of their stocks. Two alternative techniques, multiple discriminant anal...

Data flow diagrams (DFDs) are commonly used models for representing business processes. The traditional presentation of DFDs provides separate views of major system processes from views of their subprocesses. This separates the details of the low-level system activities from their context. Although this separation can reduce information overload, i...

This research focuses on the information overload problem on the Internet, and proposes a potential remedy to the overload encountered while searching the Web. We developed a system that makes use of clustering and visualization for browsing the results of a typical web search. We built two different (full and fisheye) zooming capabilities into our...

This study addresses the information overload problem that one faces while browsing the results of a web search query. The increasing indexing capabilities of the commercial web search engines makes it common for a broadly formulated search query to result in thousands of web documents. This causes a nontrivial overload problem. Our study proposes...

Recent strides in computing and telecommunications have provided managers with access to ever increasing amounts of data through higher speed computers and extensive connectivity.
