Artificial Intelligence Lab, Department of MIS, University of Arizona / Areas related to nanotechnology, or nanoscale science and engineering (NSSE), have experienced tremendous growth over the past few years. While there are a large variety of useful resources available on the Web, such information are usually distributed and difficult to locate, resulting in the problem of information overload. To address the problem, we developed the NanoPort system, an integrated Web portal aiming to provide a one-stop shopping service to satisfy the information needs of researchers and practitioners in the field of NSSE [1]. We believe that the approaches taken also can be applied to other domains.

Artificial Intelligence Lab, Department of MIS, University of Arizona / Search engines and data mining are two research areas that have experienced significant progress over the past few years. Overwhelming acceptance of the Internet as a primary medium for content delivery and business transactions has created unique opportunities and challenges for researchers. The richness of the webâ s multimedia content, the reach and timeliness of web-based publication, the proliferation of e-commerce activities and the potential for wireless web delivery have generated many interesting research problems. Technical, system, organizational and social research approaches are all needed to address these research problems. Many interesting webretrieval and mining research topics have emerged recently. These include, but are not limited to, the following: text and data mining on the web, web visualization, web intelligence and agents, web-based decision support and knowledge management, wireless web retrieval and visualization, web-based usability methodology, web-based analysis for eCommerce applications. This special issue consists of nine papers that report research in web retrieval and mining.

The authors use an exploratory project involving Web resources related to Alzheimer’s Disease to explore ways in RDF metadata can more effectively translate the virtues of the traditional vertical file to a Web environment form using Semantic Web descriptive standards. In so doing, they argue against the separation of “bibliographic control” from the socially-embedded institutional practices of reference work, collection development, and the management of information ephemera. Libraries of the future will use specific Web technologies that lend themselves to sophisticated and rigorous knowledge structures, and link them with librarians’ skills in information harvesting and evaluation.

This paper describes an exploratory, multisite case study of the production of textual content for state agency Web sites. The qualitative field study explored internal agency Web staff characterizations of textual Web content and staff perceptions of factors affecting the production of content. Study results suggest that staff characterize content in terms of its format, its style age, its rate of change, its degree of change, its owner, and the degree to which it is sensitive. Staff described nine factors affecting content production including information intensity, public education mission, public inquiry burden, top-down directives, existing maintenance burden, review and approval process, resources, management interest and goals, and support from other program staff. A better understanding of how internal agency staff perceive and treat content is important because staff play a large role in determining what content is produced and what characteristics the content contains. The inclusion or exclusion of certain characteristics in content has important implications for information usability, costs, citizen participation in agency policymaking, government transparency, and public trust in government.

Over recent years the cadastral industry has become increasingly reliant on digital data. Many surveyors now submit digital survey plan data to accompany the legally required hardcopy maps and documentation, although it will not be long before total digital lodgement will be possible. In this environment it will be ideal to capitalise on computer networking technology such as the present day Internet and World Wide Web (WWW) to better facilitate the transmission of digital data. This work provides a study of the current climate in the cadastral industry and further identifies how the Internet and its related technologies can be used to facilitate the transmission of digital cadastral data. The focus is to provide a prototype application that facilitates these data transactions in the most effective manner that benefits both user and data provider. This involves a study of the different underlying Internet technologies and how they can be used within the cadastral context. The work presents how the Internet and the WWW can bring benefits in the form of increased data distribution, and, in data integration and update for data maintainers, who need efficient ways of passing digital data to and from different locations.
