Mechanisms for generating a set of questions to evaluate a link between concept entities are provided. A hypothetical link between at least two information concept entities is generated. A set of questions corresponding to the hypothetical link is retrieved and pruned into a subset of questions based on at least one of characteristics of the hypothetical link or characteristics of the at least two information concept entities. The pruned set of questions is processed based on a corpus of evidence to generate a measure of support for or against the hypothetical link being an actual link between the at least two information concept entities. A validity indication for the hypothetical link indicating whether or not the hypothetical link is an actual link between the at least two information concept entities is output.
