Title:
オブジェクト間の競合指標計算方法およびシステム
Document Type and Number:
Japanese Patent JP5057474
Kind Code:
B2
Abstract:
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, the first and second objects having a first profile and a second profile, each composed of a plurality of attributes, respectively; normalizing the first profile and the second profile with reference to ontology information; and calculating, based on the normalized first and second profiles, a competitiveness metric between the first and second objects. In one embodiment, the ontology information is a common attribute name vocabulary, and the step of normalizing is configured for adjusting the structures of the first and second profiles to a unified profile structure, computing the sub-metrics between the corresponding attributes in the unified profile, and computing the weighed sum of the sub-metrics as the final competitiveness metric of the first and second objects. In another embodiment, the ontology information is an object category tree, and the step of normalizing is configured for mapping the first and second profiles to one or more nodes in the object category tree, computing the probabilities of mapping the profiles to different nodes, and then, based on the obtained semantic distances between the nodes, computing the final competitiveness metric according the probabilities and the semantic distances.
