Search of sources and targets based on relative expertise of the sources
First Claim
1. A system, comprising:
- at least one or more processors;
a citation search engine with the at least one or more processors that in operation retrieves a plurality of citations composed by a plurality of subjects citing a plurality of objects that fit one or more search criteria,a citation graph coupled to the citation engine, the citation graph used to determine an influence of each of the subjects and the objects, the citation graph including the plurality of citations each describing an opinion of an object by a subject, the citation graph including nodes or entities that are
1) subjects that have an opinion or making citations, and
2) objects cited by citations relative to subjects that have opinions or make citations;
an influence evaluation engine with the at least one or more processors that in operation, determines an expertise of a subject as a measure of the subject'"'"'s expertise in a topic relative to a larger population of multiple subjects and allows for determination of expertise on any query term in real-time; and
an object/subject selection engine with the at least one or more processors, which in operation;
ranks the cited objects of the plurality of citations using the influence and relative expertise of the subjects, andselects objects as the search result for the user based on the matching of the objects with the search criteria as well as the relative expertise of the citing subjects.

Abstract
A new approach is proposed that contemplates systems and methods to provide a ranking of citied objects and citing subjects identified as results of a search, where the relative expertise of subjects or sources of citations to said targets or objects is considered. The relative expertise is a function of the share of the subject'"'"'s citations matching the query term or search criteria relative to the share of all subjects'"'"' citations matching the query term, weighted by the influence of the subjects. This allows the identification of “experts” on “topics” without any pre-defined categorization of topics or pre-computation of expertise. Under this novel approach, expertise can be determined on any query term in real-time.
