17. The apparatus of claim 15 , wherein the set of questions is generated by performing a lookup in a question template database of types of the information concept entities and a type of a relationship specified by the hypothetical link to identify a set of question templates corresponding to the types of information concept entities and type of relationship.
15. An apparatus comprising: a processor; and a memory coupled to the processor, wherein the memory comprises instructions which, when executed by the processor, cause the processor to: receive a set of evidential data specifying a plurality of information concept entities; analyze 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 generate 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; retrieve a set of questions corresponding to the hypothetical link between the at least two information concept entities; prune 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; process 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 output 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.
