Abstract: A referral system is provided with an on-line social network system. The referral system selects a set of (connected profile, job posting) pairs for presentation to a member of the on-line social network system who is an employee of a particular target organization, based on each pair's respective presentation score. The presentation score for a (connected profile, job posting) pair reflects likelihood that the employee refers a candidate represented by the connected profile from the (connected profile, job posting) pair for the job represented by the job posting from the (connected profile, job posting) pair.

Abstract: A referral system is provided with an on-line social network system. The referral system accesses a member profile representing an employee of a certain company. For each job posting that represents a job at the target organization, the referral system generates a presentation score that reflects the likelihood of the employee referring someone from their network for the job represented by that job posting. The referral system uses respective presentation scores generated for the job postings to determine which of these job postings are to be selected for inclusion into a referral UI for presentation to the employee.

Abstract: A referral system is provided with an on-line social network system. The referral system accesses a member profile representing an employee of a certain company (employee member profile) and a connected member profile representing the employee's connection in the on-line social network. The referral system then examines the job postings that represents job openings at the employee's company and selects a presentation set of job postings based on (1) fitness of the candidate represented by the connected member profile for a job represented by the job posting and (2) familiarity of the employee with the job.

Abstract: A referral system is provided with an on-line social network system. The referral system accesses a member profile representing an employee of a certain company and a target job posting representing a job opening at the same company. The referral system analyzes respective profiles of the member's connections in relation to the target job posting. For each connected member profile, the referral system generates a presentation score with respect to the job posting. The presentation score generated reflects likelihood that that particular employee refers a candidate represented by the connected member profile for the job represented by the target job posting and is used to determine which connected member profiles are to be presented to the employee.
