Abstract: Provided are methods and systems for computational quantification of an entity's affinity to a qualitative issue defined with Boolean data in a computing system. The disclosed invention provides for a system for rating a first entity's affinity to an issue through information provided by the entity itself, or derived from information provided by other entities related to the first entity. Further, a first entity's affinity to a group of political issues defined as an umbrella issue can also be rated.
