1. A system comprising: an associative memory, embodied as a non-transitory computer readable storage medium, comprising a plurality of data and a plurality of associations among the plurality of data, wherein the plurality of data is collected into associated groups, wherein the associative memory is configured to be queried based on at least indirect relationships among the plurality of data; an input device, comprising a tangible input device, in communication with the associative memory, the input device configured to receive a query to compare entities in the associative memory; and a coordinator, embodied as a processor, in communication with the associative memory, the coordinator configured to compare the entities to identify a similar attribute value among the entities, the coordinator further configured to identify a differentiator among the entities, wherein the differentiator comprises an attribute value of a given entity that is unique relative to all other attribute values of comparable entities having category types equal to a category type of the given entity, and wherein the differentiator is further relevant to the query, wherein the coordinator is further configured to identify the differentiator by receiving a value identifying a depth of an attribute of an entity to include, and wherein the coordinator is further configured to identify the differentiator by removing common attribute values that are common to any two of the entities and are relevant to the query.
