Abstract: The technical problem of automatically facilitating a career transition that is a career pivot is addressed by providing a career navigator component in an on-line connection network system. The career navigator is configured to determine that a member's intent is to pivot in their career and, in response, identify, rank, and surface member profiles that indicate the same pivot. The operations for recognizing a pivot intent include maintaining hierarchical occupation taxonomy that can be consulted to determine whether the member's activities on the web site relate to the same or different parent occupations. Once the pivot intent has been recognized, the career navigator identifies those member profiles that indicate the same career transition, and presents those profiles to the pivoting member via a custom-generated user interface.
