Experts may be modeled as managing the inductive dynamics of knowledge acquisition in the knowledge processes of society. Who becomes an expert may be modeled as a random process under the influence of strong positive feedback loops in the social mechanisms giving access to knowledge. These models have implications for the design of expert systems. 1 The Nature of Expertise Expert systems add a...

This article outlines new technologies in the areas of automated expertise finding, expert network discover, virtual place-based collaboration, and automated question answering. We illustrate each of these areas with implemented and in some cases empirically evaluated systems. Collectively, these illustrate new methods for automatic discovery of knowledge, experts, and communities in an effecti...

People often use expert advice when making decisions in our society, but how we are influenced by this advice has yet to be understood. To address this, using functional magnetic resonance imaging, we provided expert and novice advice to participants during an estimation task. Participants reported that they valued expert advice more than novice advice, and activity in the ventral striatum corr...

Reviewers: This report has benefited greatly by the expertise, policy direction and editorial advice offered by the following reviewers in Halton Region Health Department:

Complex modern-day artifacts are designed cooperatively by groups of experts, each with their own areas of expertise. The interaction of such experts inevitably involves conflict. This paper presents an implemented computational model, based on studies of human cooperative design, for supporting the resolution of such conflicts. This model is based centrally on the insights that general conflic...

Although individuals can derive substantial benefits from exchanging information and ideas, many individuals are reluctant to seek advice from others. We find that people are reticent to seek advice for fear of appearing incompetent. This fear, however, is misplaced. We demonstrate that individuals perceive those who seek advice as more competent than those who do not seek advice. This effect i...
