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.

21. A system, comprising:
-
a processor; a memory coupled to the processor though a bus; and a process executed from the memory by the processor causes the processor to retrieve a plurality of citations composed by a plurality of subjects citing a plurality of objects that fit one or more search criteria, determine an influence of each of the subjects and the objects using a citation graph, wherein the citation graph including the plurality of citations each describing an opinion of an object by a subject, the citation graph further including nodes or entities that are subjects that have an opinion or creating making citations and objects cited by citations relative to subjects that have opinions or make citations, determine 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 allow for determination of expertise on any query term in real-time, rank the cited objects of the plurality of citations using the influence and relative expertise of the subjects, and select 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. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29, 30, 31)

using a processor the at least one or more processors to select 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. - View Dependent Claims (33, 34, 35, 36, 37, 38)

a processor; a memory coupled to the processor though a bus; and a process executed from the memory by the processor causes the processor to retrieve a plurality of citations composed by a plurality of subjects citing a plurality of objects that fit one or more search criteria, determine an influence of each of the subjects and the objects using the citation graph, the citation graph including the plurality of citations each describing an opinion of an object by subject, the citation graph including nodes or entities that are subjects that have an opinion or making citations, and objects cited by citations relative to subjects that have opinions or make citations, determine 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 allow for determination of expertise on any query term in real-time, rank the citing subjects of the plurality of citations using the influence and relative expertise of the subjects, and select subjects as the search result for the user based on the influence scores and/or the relative expertise of the citing subjects.
