Systems and method for simultaneous relevance and variety control in audience targeting

A computer implemented system for controlling relevance and variety of stored data in data management platforms for audience targeting, the system comprising:

• an input means (202) configured to receive an input query from a user;
• a database (210) configured to store and index the target audience;
• a memory to store a plurality of instructions;
• a processor configured to receive the input query and execute the plurality of instructions stored in the memory comprising,
• an expansion module (206) configured to provide an expanded set of search queries from the input query based on the input query by using a language model (208),
• a search module (212) configure to provide a result of matched target audiences based on the expanded set of search queries matched with the target audiences stored in the database (210);
• a relevance module (214) configured to provide a filtered result of the matched target audiences by discarding non-relevant target audience from the received matched target audience based on preset calculations;
• a variety module (216) configured to perform multiscale clustering to provide a graphical representation of the filtered matched target audiences based on a weightage score, and
• a display unit configured to show the graphical representation of the previous step as a ranked list of associated documents.
