Systems and methods of a platform for candidate identification

A computer-implemented system comprising:

• a user interface in a marketplace structured for a plurality of candidates to each populate a user profile with data items, wherein each candidate separately subscribes to the marketplace;
• a processor structured to assign a score and a category label for each data item in each user profile, wherein a cumulative score is populated for each user profile by summing individual scores and wherein at least one top-level category is optionally assigned for each user profile;
• wherein the processor receives a search query, through the user interface, comprising at least one of a desired cumulative score range, a desired score range for one or more category labels, and one or more top-level categories;
• wherein the processor outputs a subset of the plurality of user profiles, through the user interface, wherein the subset of the plurality of user profiles match the search query;
• wherein the processor ranks the user profiles in accordance with at least one of the cumulative score range, the score range or the top-level categories to obtain a ranking;
• and
• wherein the search query is based on category labels that are missing or disproportionately under-represented in a third-party group but which are represented in the plurality of candidates.
