—In our work, an agent-based system supporting workers in fulfilling their roles in a virtual organization has as its centerpiece ontologically demarcated data. In such system, ontological matchmaking is one of key functionalities in provisioning of personalized information. Here, we discuss how matchmaking will be facilitated in a Duty Trip Support(More)
Dietary saturated fatty acids are implicated as a risk factor for atherosclerosis. The conversion of the major dietary saturated fatty acids stearic acid (18:0) and palmitic acid (16:0) to monounsaturated fatty acids in whole plasma and lipoprotein fractions is reported for seven healthy adult humans over 6 d using [U-13C]stearic acid (18:0*) and(More)
In our work, an agent-based system supporting workers in an organization is centered around utilization of ontologically demarcated data. In this system, ontological matchmaking, understood as a way of establishing closeness between resources, is one of key functionalities. Specifically , it is used to autonomously provide recommendations to the user, who(More)
