PURPOSE: A method for calculating the link-based similarity by using reaching probability and a device thereof are provided to generate vectors corresponding to an object based on a link between the objects, to and use the cosine similarity between the vectors, thereby calculating the similarity between the objects. CONSTITUTION: A storage unit (410) stores information of objects, and a processing unit (420) obtains information of the objects from the storage unit and generates vectors corresponding to the objects. The processing unit selects two vectors of the vectors, calculates the cosine similarity between the selected vectors, and determines the similarity between the objects corresponding to the vectors based on the cosine similarity. A providing unit (430) provides the determined similarity, and the elements in the vectors correspond to one object of the objects.
