Claim 10:
11. A system for debiasing a recommendation engine, comprising:
a communication port configured to access current a search query associated with a user profile and a plurality of search queries associated with the user profile, wherein a result set of content items was generated for the current search query and wherein a respective result set of content items was generated for each of the plurality of search queries; and
processing circuitry configured to:
generate, for each of the plurality of search queries, a respective bias score based on the respective result set;
generate a time-averaged bias score associated with the user profile and based on computing an average of all the respective bias scores generated for the plurality of search queries over a period of time;
generate, based on the result set for the current search query, a current bias score for a content attribute;
determine, based on the current bias score and the time-averaged bias score, whether a bias is signaled for the content attribute; and
output, for display via a computing device, the result set or a debiased result set based on the determination of whether the bias is signaled.
