Despite the importance of these reports, practically physicians do not give a feedback about radiology reports. This study was aimed to determine the opinions of specialists towards radiology reports. Methods: in this descriptive study, sample consisted of all specialists working ...

An important question when eliciting opinions from experts is how to aggregate the reported opinions. In this paper, we propose a pooling method to aggregate expert opinions. Intuitively, it works as if the experts were continuously updating their opinions in order to accommodate the expertise of others. Each updated opinion takes the form of a linear opinion pool, where the weight that an expe...

Opinion formation describes the dynamics of opinions in a group of interaction agents and is a powerful tool for predicting the evolution and di usion of the opinions. The existing opinion formation studies assume that the agents express their opinions by using the exact number, i.e., the exact opinions. However, when people express their opinions, sentiments, and support emotions regarding di ...

Recommendations are based on either experimental results or opinion, with the latter being considered of uniformly lower evidentiary importance. The contribution of opinion to the guidelines is substantial in that opinion supports...

Identifying sentiments (the affective parts of opinions) is a challenging problem. We present a system that, given a topic, automatically finds the people who hold opinions about that topic and the sentiment of each opinion. The system contains a module for determining word sentiment and another for combining sentiments within a sentence. We experiment with various models of classifying and com...

Consider a group of individuals with unobservable perspectives (subjective prior beliefs) about a sequence of states. In each period, each individual receives private information about the current state and forms an opinion (a posterior belief). He also chooses a target individual whose opinion is then observed. This choice involves a fundamental trade-off between well-informed targets, whose s...

We describe a viewpoint on the Dcmpstcr/Shafcr "Theory of Evidence", and provide an interpretation which regards the combination formulas as statistics of the opinions of "experts". This is done by introducing spaces with binary operations that arc simpler to interpret or simpler to implement than the standard combination formula, and showing that these spaces can be mapped homomorphically onto...
