Abstract: The disclosed embodiments provide a system for processing a query for a ranking of candidates for an opportunity. During operation, the system obtains parameters associated with a query for a ranking of candidates for an opportunity, wherein the parameters include a candidate and the opportunity. Next, the system matches one or more of the parameters to a fixed number of quantile thresholds calculated from a distribution of scores for the candidates. The system then estimates, based on the fixed number of quantile thresholds, a quantile for a score of the candidate. Finally, the system outputs a position of the candidate within the ranking based on the estimated quantile.

Abstract: Methods, systems, and computer programs are presented for embedding user categories into vectors that capture similarities between the user categories. One method includes an operation for building a graph for a category of attributes for users of a social network, the graph including a vertex for each category value. Connections, built between the graph vertices, have a connection value indicating the number of users to which the category values associated with the vertices have been assigned. Further, a first vector for each category value is obtained based on the graph, where a distance between two category values is a function of the connection value between the corresponding vertices. A user vector, based on the first vectors of the category values, is assigned to each user. A search is performed for a given user based on the user vectors, and results are presented to the given user.

Abstract: In some embodiments, a computer system generates a recommendation for a user of an online service based on user actions that have been performed by the user within a threshold amount of time before the generation of the recommendation. For each user action, the computer system determines an intent classification that identifies an activity of the user and that corresponds to different types of user actions, as well as a preference classification that identifies a target of the activity, and then stores these intent and preference classifications as part of indications of the user actions for use in generating different types of recommendations using different types of recommendation models. Additionally, the computer system may use mini-batches of data from an incoming stream of logged data to train an incremental update to one or more recommendation models.

Abstract: A skills classification system is configured to calculate, for a skill from the skills database, industry-specific probabilities for the industries associated with the skill. An industry-specific probability for an industry with respect to a skill is the probability of that skill being a required skill for a job associated with that industry. The skills classification system also calculates an industry-agnostic probability with respect to that same skill, which is the probability of the skill being a required skills for any job regardless of the industry. Based on the distance between the set of industry-specific probabilities for the industries associated with the skill and the industry-agnostic probability, the skills classification system calculates a score for the skill. This score is used to determine whether the skill should be tagged with a soft skill identifier or a hard skill identifier.

Abstract: The disclosed embodiments provide a system for performing adaptive interview preparation for candidates. During operation, the system obtains a graph-based representation of potential questions for a candidate during an interview. Next, the system receives an answer by the candidate to a first question included in the graph-based representation. The system then calculates similarities between the answer and a set of sample answers to the first question. Finally, the system selects a second question for presentation to the candidate in the interview based on a highest similarity of the answer to a sample answer in the set of sample answers and an edge between the first and second questions in the graph-based representation. The system further triggers presentation of the selected second question to the candidate.

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.
