17. An assisted decision making system, comprising: a processor; and a memory comprising: a knowledge base comprising a plurality of executable stories, a given executable story comprising: an executable belief network comprising a plurality of hypotheses; and a plurality of evidence templates representing respective text segments containing information related to the plurality of hypotheses comprising the belief network, a given evidence template listing at least two of the location, magnitude, mechanism, and associated actor of an event of interest described in a represented text segment; and computer executable instructions, executed by the processor, comprising: at least one information extractor that reduces evidence from an external source into evidence templates that are appropriately formatted for the knowledge base; at least one evidence classifier that evaluates the evidence templates to associate each template with a hypothesis within the knowledge base; a plurality of decision algorithms that retrieve executable stories from the knowledge base, modify the retrieved executable stories, and return the modified stories to the knowledge base; and a translation interface that converts a given story from the knowledge base into a format associated with at least one of the plurality of decision algorithms.
20. The system of claim 17 , further comprising a fusion engine that is operative to add and remove hypotheses from the plurality of executable stories associated with a given executable story, and modify the plurality of hypotheses associated with the executable story.
