Abstract: A computer-implemented method and system for ranking information in an information system comprising linked objects is disclosed. The computer-implemented method comprises computing a prior ranking of all objects in the linked database, obtaining at least one source object, determining the probability of reaching an object taking a step in random walk with restart in the at least one source object(s) based on the adjacency between objects in the information system, and determining a ranking of objects in the information system using the determined probability and applying a correction factor inversely proportional with the computed prior ranking of the objects. An output based on the determined ranking is provided. The present invention also relates to a computer-implemented method and system for providing probable functional relations between at least one source object and a target object, as well as computer-related products therefor.
