Abstract

Starting with a dictionary including concepts and chains, a subset of the chains is selected as intentional stance basis chains (ISBCs). Concepts in the dictionary are chosen and mapped to state vectors using the ISBCs. The state vectors are assembled into a template, and an action and threshold distance are assigned to the template. When an impact summary is generated for a content source, the distance between the impact summary and the template is measured. If the distance is less than the threshold distance associated with the action for the template, the action is performed.
