Abstract
Systems and methods are provided for assisted decision-making. A knowledge base comprises a plurality of executable stories. A given story comprises a belief network containing at least one associated hypothesis and evidence associated with the at least one hypothesis. The system further comprises at least one decision algorithm having respective associated input formats. A translation interface is operative to convert a given story from the knowledge base into a decision network having a format associated with the at least one decision algorithm.
Claims20
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 a plurality of decision algorithms that retrieve executable stories from the knowledge base, modify the retrieved executable stories, and return the modified executable stories to the knowledge base.
A computer readable medium, operative in a general purpose processor, 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
- 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.
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.
