1. A method, in a data processing system, for generating a set of questions to evaluate a link between concept entities, comprising: receiving, by the data processing system, a set of evidential data specifying a plurality of information concept entities; analyzing, by the data processing system, an ontological data structure associated with the set of evidential data to identify potential ontological relationships between information concept entities in the plurality of information concept entities; automatically generating, by the data processing system, a hypothetical link between at least two information concept entities in the plurality of information concept entities based on results of the analysis, wherein the hypothetical link represents a scenario involving the at least two information concept entities; retrieving, by the data processing system, a set of questions corresponding to the hypothetical link between the at least two information concept entities; pruning, by the data processing system, the set of questions 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; processing, by the data processing system, the pruned set of questions based on a corpus of evidence to thereby generate a measure of support for or against the hypothetical link being an actual link between the at least two information concept entities; and outputting, by the data processing system, an 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.
