Argues that the best strategy for building integrated, personalized information systems consists of linguistically oriented knowledge and inference, rather than artificial intelligence techniques. The discussion addresses difficulties in the evaluation of such systems and strategies for devising performance studies. (five references) (CLB)

Discussion of the use of scientific information disseminated in primary subject literature focuses on a study that developed a methodology for hypothesis testing that measured document obsolescence by means of citation analysis and content obsolescence by expert opinions and then compared the results. Information validity and information utility…

Discusses two models of selecting information sources--Cost/Benefit (information seekers select sources on basis of expected benefits and costs), and Least-Effort (seekers select sources on basis of minimizing effort or cost). Results of a study proposing that users place different weights on costs and benefits are presented. (EJS)
