Content search based on correlating a user propensity with propensity of content providers

A system for processing a search query comprising:

• one or more memories;
• and
• at least one processor coupled to the one or more memories and configured to:
• cluster content providers based on attributes of the content providers to produce a plurality of clusters each having content providers with aligned attributes;
• determine a correlation strength for each cluster indicating reliability of that cluster based on an amount of change to cluster attributes in response to conditions;
• determine a correlation between a user providing the search query and the clusters based on the correlation strength and attributes of the user relative to attributes of the clusters;
• determine a cluster from among the plurality of clusters based on the correlation;
• and
• retrieve content satisfying the search query from the content providers of the determined cluster.

A computer program product for processing a search query, the computer program product comprising one or more computer readable storage media having program instructions collectively stored on the one or more computer readable storage media, the program instructions executable by at least one processor to cause the at least one processor to:

• cluster content providers based on attributes of the content providers to produce a plurality of clusters each having content providers with aligned attributes;
• determine a correlation strength for each cluster indicating reliability of that cluster based on an amount of change to cluster attributes in response to conditions;
• determine a correlation between a user providing the search query and the clusters based on the correlation strength and attributes of the user relative to attributes of the clusters;
• determine a cluster from among the plurality of clusters based on the correlation;
• and
• retrieve content satisfying the search query from the content providers of the determined cluster.
