1. A system, comprising: a citation search engine that includes a processor, which in operation, retrieves a plurality of citations composed by a plurality of subjects citing a plurality of objects that fit a searching query specified by a user; an influence evaluation engine that includes a processor, which in operation, creates a list of the plurality of subjects from the user's perspective and calculates the influence scores of the plurality of subjects on the user by flattening a user's influence network of subjects up to a given number of degrees, levels, or depth, wherein the list of plurality of subjects from the user's perspective are subjects that are in the user's influence network of subjects and the user's influence network includes subjects that are connected to the user either directly or indirectly through other sources; and an object/subject selection engine that includes a processor, which in operation, ranks the plurality of objects of the plurality of citations from the user's perspective using a bias filter, wherein the bias filter includes a ranking function based on the influence scores of the list of plurality of subjects and an inverse number of links of those plurality of subjects from the user's perspective, and selects objects from the plurality of objects as the search result for the user based on matching of the objects with the searching query as well as the influence scores of the plurality of subjects on the user.
