1. A method for ranking the quality of a first information source of a plurality of information sources with respect to a patent claim in a collaboration and analysis system, the first information source having a first information disclosure, comprising: storing the plurality of information sources in a database; processing a first patent claim to derive a first set of one or more core concepts; processing the first patent claim to derive a first set of one or more claim limitations; processing a second patent claim to derive a second set of one or more claim limitations; processing the first set of core concepts to assign a core rating to each core concept based upon a precision of the first information disclosure of the first information source with respect to each core concept of the first set of core concepts; processing a ranking for the first information source to determine a core rating for each core concept of the first set of core concepts for the first set of claim limitations; processing at least one association between a claim limitation of the first set of claim limitations and a claim limitation of the second set of claim limitations; and processing the second set of claim limitations to assign a second set of core concepts to the second set of claim limitations, wherein the second set of core concepts is based on the first set of core concepts and the second set of core concepts is assigned to the second set of claim limitations based on the at least one association between the first and second set of claim limitations.
