A concept for vertical relationship art construction methods and apparatus

The present invention provides a concept relationships for a field perpendicular to a method and apparatus construction. The method may comprise: determining a close relationship concept based on the vertical field of knowledge conceptual hierarchy and the concepts of parity relations, the search behavior of the user, the user clicks the behavior of one or more closely wherein said concepts relationship is used to describe the degree of association meet user demand between any two aspects of the same concept in the field of vertical attribute. The above-described embodiment of the method and apparatus capable characterize the correlation between the two concepts at the same attribute from the user's demand perspective, expanded description of the embodiment of the concept of the relationship between the vertical field.
