The paper aims to explore the concepts of interaction and interactivity presented in different theoretical models in the fields of human‐computer interaction (HCI) and information‐seeking/searching behaviour, and to relate these to information retrieval (IR) research. It is suggested that...

Neural networks have been applied in a wide variety of business domains. Although databases used in many organizations have been found to contain errors, little is known about the effect of these errors on predictions made by neural network models. The article uses a real-world example, the...

Research on information systems (IS) use has often relied upon retrospective self-reports. One example is when the amount of time spent using a system is reported, often as an indication of user acceptance. In this study, self-assessments of computer usage are compared with computer-monitored...

Spreadsheet software packages find ready applications in Western ations with a high proportion of PCs having a spreadsheet package installed. In Taiwan there is a high degree of acceptance of this class of software. In the People′s Republic of China, however, there is not the same degree of...

Spreadsheet models are used extensively in business as an important aid in decision support particularly in areas like financial analysis, budgeting and forecasting. If these models were compromised through quantitative and qualitative errors, the resulting decision making would be based on...

The information system downsizing trend has been on the increase during the last five years because of extreme pressures brought about by the slow economy and intense global competition. The major benefit of downsizing is cost saving or cost avoidance, though reports of downsizing show that not...

The user interface is defined as the link between the computer and the user. With organizations striving to increase productivity, focus must be shifted from the capabilities of the machine to the ability of the user. Research has shown that the use of the graphic user interface leads to a...
