Abstract
Mechanisms for evaluating a link between information concept entities are provided. A set of evidential data specifying a plurality of information concept entities is received and a link between at least two information concept entities in the set of evidential data is generated. The set of evidential data is evaluated with regard to whether or not the set of evidential data supports or refutes the link. The evaluation of the set of evidential data comprises analyzing language of natural language statements in the set of evidential data to identify certainty terms within the natural language statements. A confidence value for the link is calculated based on results of the evaluation of the set of evidential data and a knowledge output is generated based on the link and the confidence value associated with the link.
