• generate a reduced dataset based on the obtained dataset, the generating including:
• generating a reduced set of landing pages based on the initial set of landing pages using parameters of links associated with the respective landing pages,
• clustering the keywords to determine a set of themes associated with the dataset, and
• generating a reduced set of groups, including identifying overlaps in themes included in the set of themes, between the groups;
• and
• use the reduced dataset to map a received search term to one or more of the content items.
