Claim 0:
1. A method for debiasing a recommendation engine, comprising:
accessing, by control circuitry, a plurality of search queries associated with a user profile, wherein a respective result set of content items was generated for each of the plurality of search queries;
generating, for each of the plurality of search queries, a respective bias score based on the respective result set;
generating a time-averaged bias score associated with the user profile and based on computing an average of all the generated respective bias scores for the plurality of search queries over a period of time;
accessing, by the control circuitry, a current search query associated with the user profile, wherein a result set of content items was generated for the current search query;
generating, based on the result set for the current search query, a current bias score for a content attribute;
determining, based on the current bias score and the time-averaged bias score, whether a bias is signaled for the content attribute; and
outputting, for display via a computing device, the result set or a debiased result set based the determination of whether the bias is signaled.
