Web- and telephone-based remote electronic voting systems (REVS) offer a solution to the problems of manual counting, counting accuracy, timeliness of reporting results and reducing the inconvenience of voting. However, while access to telephones is ubiquitous, the unequal use and access to Internet technology across different demographic groups in...
Article
The experience of the state governments with regards to the challenges faced by them and the pursuit of the human resource management (HRM) practices to become an employer of choice, are discussed. While the need for information technology (IT) workers and previous severe shortages placed stresses on all sectors, states felt these stresses more acu...

Remote electronic voting systems (REVSs) have become a viable mechanism for official political elections. As an entirely automatic, electronic, technology-based voting environment, REVSs can enable remote voting, facilitate monitoring, voting and tallying, eliminate manual registration verification, and report immediate and accurate results. Howeve...
Article
This research seeks to identify factors that influence high school students' software usage. Students in our study have been observed to vary with respect to their use of a specific software application, Geometer's Sketchpad®. The use of Geometer's Sketchpad® is mandatory in Geometry class. However, some students have voluntarily expanded their use...
Article
This research investigated the application of techniques successfully used in previous information retrieval research, to the more challenging area of medical informatics. It was performed on a biomedical document collection testbed, CANCERLIT, provided by the National Cancer Institute (NCI), which contains information on all types of cancer therap...
Article
AbstractThe location and provision of information services has dramatically changed over the last ten years. There is no need to leave the home or office to locate and access information now readily available on-line via digital gateways furnished by a wide variety of information providers, (e.g. libraries, electronic publishers, businesses, organi...

d/or searching the Internet. Our results indicate that a Kohonen self-organizing map ( SOM ) -based 1. Introduction algorithm can successfully categorize a large and eclectic Internet information space ( the Entertainment sub- The Information Age has produced a wealth of infor- category of Yahoo! ) into manageable sub-spaces that mation which is su...
Article
This paper presents a neural network approach to document semantic indexing. A Hopfield net algorithm was used to simulate human associative memory for concept exploration in the domain of computer science and engineering. INSPEC, a collection of more than 320,000 document abstracts from leading journals, was used as the document testbed. Benchmark...
Article
The Internet provides an exceptional testbed for developing algorithms that can improve browsing and searching large information spaces. Browsing and searching tasks are susceptible to problems of information overload and vocabulary differences. Much of the current research is aimed at the development and refinement of algorithms to improve browsin...
Conference Paper
Ranking based on passages addresses some of the shortcomings of whole-document ranking. It provides convenient units of text to return to the user, avoids the difficulties of comparing documents of different length, and enables identification of ...
Conference Paper
Full-text available
We describe the use of ethnomethodologically-informed ethnography as a means of informing the requirements elicitation, design, development and evaluation of digital libraries. We present the case for the contribution of such studies to the development ...
Article
An experiment with an AI-based software agent shows that it can help users organize and consolidate ideas from electronic brainstorming. The agent recalled concepts as effectively as experienced human meeting facilitators and in a fifth of the time. Agent software enhances the productivity of groupware by helping perform convergent tasks, thus free...
Conference Paper
Digitized textual information is an increasingly common repository for organizational memory. This paper describes an AI based tool that was developed at the University of Arizona which can be used to organize, categorize and extract digitized textual information from a Group Support System (GSS), GroupSystems V@. The first sections describe two ex...
Conference Paper
Full-text available
Diplomats and other experts are sent as delegations to inter-governmental conferences to implement their governments ' policies. Individual delegates in a multi- lateral diplomatic conference environment have needs for simultaneous any-time/any-place types of information and communication that have not been met by either traditional GSS studies in...
