Abstract: A first user of a presentation machine may be a recruiter that initiates an action in reference to a first user profile. The first user profile may describe a first candidate for a job. The presentation machine may identify the first user profile and determine a similarity score that indicates a degree of similarity between the first user profile and a second user profile that describes a second candidate for the job. The presentation machine may also access a volatility score that indicates a likelihood that the second candidate is receptive to a proposal that the second candidate be employed by an employer. Based on the similarity score and on the volatility score, the presentation machine may determine a rank of the second user profile. Based on the determined rank, the presentation machine may present the second user profile to the first user.

Abstract: An online social networking system receives a message from a member of an online social networking service indicating an interest in applying for an employment position. The online social networking system compares a profile of the member against requirements for the employment position, other members of the online social networking service currently employed in the employment position, and profiles of other members who have indicated an interest in the employment position. The online social networking system computes a rank of the member based on the comparison of the profile of the member to the requirements for the employment position, the comparison of the profile of the member to the one or more members currently employed in the employment position, or the comparison of the profile of the member to the profiles of other members. The online social networking system transmits a message to the member regarding the rank of the member.

Abstract: A system may include a network interface, a user interface, and a recommendation engine. The user interface may be configured to receive a job characteristic of a job profile of a job posted to the social network and a job bid from an entity related to job to the social network. The recommendation engine may be configured to determine an aggregate job score for the user based on a relevance of the job characteristic to a user characteristic and the job bid. The network interface may be configured to transmit a message related to the job to the user based, at least in part, on the aggregate job score.
