Method and System for calculating competitiveness metric between objects are provided. The method comprises the steps of: obtaining a first object and a second object; selecting, from all the relation instances stored in a relation instance repository, associated relation instances related to the first and second objects; and calculating, based on the selected associated relation instances, an extensional competitiveness metric Sout between the first and second objects as the competitiveness metric between the first and second objects. In an embodiment, the frequency that the associated relation instances related to the first and second objects appear in all the information source documents can be used for characterizing the extensional competitiveness metric. Furthermore, the present invention also provides an integrated competitiveness metric calculation method and system for combining the intensional and extensional competitiveness analysis results.
