1. A computer-implemented method for purchasing advertising placements in advertising channels, the method comprising:
obtaining, by at least one processor, purchaser-context information representing interests of a purchaser of advertisement opportunities;
obtaining, by the at least one processor, a reference set of content as advertiser-context information representing interests of an advertiser who provides advertisement opportunities, wherein the advertiser-context information is digital data;
obtaining, by the at least one processor, user-context information representing interests of a user who views advertisement opportunities, the user-context information being digital data;
synthesizing at least one new concept from a knowledge representation embodied as a data structure stored on a non-transitory memory storage device coupled to the at least one processor, wherein the new concept is semantically relevant to the purchaser-context information, and wherein the new concept comprises at least one knowledge representation entity from the knowledge representation; and
computing, by the at least one processor executing stored program instructions, a monetary value to the purchaser of the purchaser-context information of at least one specified advertising word or phrase, at least in part by determining a semantic relevance, derived from the knowledge representation, between the new concept associated with the purchaser-context information and a plurality of second concepts from the synthesized knowledge representation associated with the at least one specified advertising word or phrase, by:
determining a semantic relevance between the new concept and each one of the second concepts based at least in part on relative positions of the new and the second concept in a topology of the synthesized knowledge representation; and
computing the monetary value of the purchaser-context information of at the least one specified advertising word or phrase as a function of the determined semantic relevance between the new concept and the plurality of second concepts;
deploying a purchasing software agent to monitor at least one advertising channel for the availability of advertisement placements associated with the purchaser-context information based on the synthesized knowledge representation; and
augmenting the user context information with the new concept associated with the purchaser-context information in response to the monetary value of the at least one specified advertising word or phrase.
