A virtual exhibition system was designed and implemented to interface with the National Archives of Singapore digital archive to support the creation of online virtual exhibitions. The XML-based digital archive provides different artefact types that form the contents in the exhibition through the reference and reuse model. Artefacts and exhibitions are endowed with rich metadata that include the Dublin Core elements to support enhanced search support for field and free text searches. An authoring tool using a grid-layout approach is used to define and lay out the exhibition contents. XML's Cascading Style Sheet and Extended Style Sheets are then selected and applied to the XML documents from the digital archive to yield the final exhibition in HTML format. By supporting the use of information layering in the descriptors of the artefacts and the application of different style sheets, it becomes possible to create multiple versions of the same exhibition that vary in content, layout and interface so that it can be used to meet the diverse information needs of a range of different user communities.

This is the second of a two-part paper to review ontology research and development, in particular, ontology mapping and evolving. Ontology is defined as a formal explicit specification of a shared conceptualization. Ontology itself is not a static model so that it must have the potential to capture changes of meanings and relations. As such, mapping and evolving ontologies is part of an essential task of ontology learning and development. Ontology mapping is concerned with reusing existing ontologies, expanding and combining them by some means and enabling a larger pool of information and knowledge in different domains to be integrated to support new communication and use. Ontology evolving, likewise, is concerned with maintaining existing ontologies and extending them as appropriate when new information or knowledge is acquired. It is apparent from the reviews that current research into semi-automatic or automatic ontology research in all the three aspects of generation, mapping and evolving have so far achieved limited success.

The business environment is increasingly becoming uncertain and complex. Environmental scanning is a systematic way for organizations to detect changes, and hence formulate adaptive strategies for coping with uncertainties. Information literacy skills are required to conduct effective and efficient environmental scanning activities as it is an information intensive process. Moreover, the development of information technology and telecommunication provides various channels and applications for accessing, processing and distributing information, which also proposes higher requirements of information literacy skills for dealing with environmental information. However, despite the number of studies undertaken to investigate the role of information literacy at the workplace, few have integrated information literacy skills with a specific business management activity or have tried to evaluate the impact of information literacy on real business applications. This paper provides an overview of environmental scanning and information literacy skills. A refined model, showing the relationship between environmental uncertainty, information literacy skills and environmental scanning, is also presented. [ABSTRACT FROM PUBLISHER]
