Accuracy of member profile retrieval using a universal concept graph

A system comprising:

• one or more hardware processors;
• and
• a machine-readable medium for storing instructions that, when executed by the one or more hardware processors, cause the system to perform operations comprising:
• accessing a first record of a database, the first record identifying a universal concept graph, the universal concept graph including a first set of nodes and a first set of edges, the first set of nodes corresponding to concept phrases included in one or more documents associated with a social networking service (SNS), the first set of edges connecting a plurality of nodes of the universal concept graph;
• accessing a second record of the database, the second record identifying a first induced concept graph associated with a job description, the first induced concept graph including a second set of nodes that represent one or more concept phrases derived from the job description, and a second set of edges that connect a plurality of nodes of the second set of nodes;
• identifying a numerical value that represents a desired number of member profiles associated with members of the SNS;
• for a member profile of one or more member profiles, generating a similarity value based on the first induced concept graph associated with the job description, and a second induced concept graph associated with the member profile, the similarity value representing a degree of similarity between the job description and the member profile;
• and
• causing a presentation of one or more identifiers of the one or more member profiles in a user interface of a client device based on the numerical value and based on similarity values associated with the one or more identifiers of the one or more member profiles.

A non-transitory machine-readable storage medium comprising instructions that, when executed by one or more processors of a machine, cause the machine to perform operations comprising:

• accessing a second record of the database, the second record identifying a first induced concept graph associated with a job description, the first induced concept graph including a second set of nodes that represent one or more concept phrases derived from the job description, and a second set of edges that connect a plurality of nodes of the second set of nodes;

• for a member profile of one or more member profiles, generating a similarity value based on the first induced concept graph associated with the job description, and a second induced concept graph associated with the member profile, the similarity value representing a degree of similarity between the job description and the member profile;
• and
