In: Journal of the American Society for Information Science and Technology. 63(2012) no.2, S.225-241.
Abstract: An efficient and robust medical-image indexing procedure should be user-oriented. It is essential to index the images at the right level of description and ensure that the indexed levels match the user's interest level. This study examines 240 medical-image descriptions produced by three different groups of medical-image users (novices, intermediates, and experts) in the area of radiography. This article reports several important findings: First, the effect of domain knowledge has a significant relationship with the use of semantic image attributes in image-users' descriptions. We found that experts employ more high-level image attributes which require high-reasoning or diagnostic knowledge to search for a medical image (Abstract Objects and Scenes) than do novices; novices are more likely to describe some basic objects which do not require much radiological knowledge to search for an image they need (Generic Objects) than are experts. Second, all image users in this study prefer to use image attributes of the semantic levels to represent the image that they desired to find, especially using those specific-level and scene-related attributes. Third, image attributes generated by medical-image users can be mapped to all levels of the pyramid model that was developed to structure visual information. Therefore, the pyramid model could be considered a robust instrument for indexing medical imagery.
3Mallen, C.: Designing intelligent help for information processing systems.
In: International journal of human-computer studies. 45(1996) no.3, S.349-377.
Abstract: The designer's description of an application contains much information that is useful in explaining its working. Extending the designer's description of the information processing system can allow for the construction of applications that are self explanatory. Defines a language which connects the designer's description with the implemented functionality of the application. Describes the extended design methodology, and outlines its use by an instructor. An electronic mail application was built, which ilustrates how the approach leads to a system capable of supplying intelligent help

In: Proceedings of the 15th National Online Meeting 1994, New York, 10-12 May 1994. Ed. by M.E. Williams. Medford, NJ : Learned Information, 1994. S.15-28.
Abstract: Globalization of the marketplace has presented challenges as well as opportunities for organizations in service, financial and manufacturing sectors. To be a player in the global market, organizations must have access to timely international information. Increasing cross-border competition demands competitive intelligence efforts that monitor financial and news sources for information on foreign as well as domestic competitors. To investigate opportunities for trading partners, strategic alliances, joint ventures and other investments in the developing markets in Latin America, Eastern Europe and the Pacific Rim, organizations need information concerning the volatile markets, economies and political situations
