Title
(EN) Systems and methods for re-ranking ranked search results
Abstract
(EN)

A system, computer-readable storage medium storing at least one program, and a computer-implemented method for re-ranking ranked search results is presented. Ranked search results satisfying a search query are obtained, where the ranked search results include a first search result corresponding to a first document associated with a first entity and a second search result corresponding to a second document associated with a second entity, and where the first search result is ranked higher than the second search result. The first document and the second document are determined to satisfy a similarity criterion. The second entity is determined to satisfy a predefined authorship differential with respect to the first entity. Responsive to determining that the second entity satisfies the predefined authorship differential with respect to the first entity, the second search result and the first search result in the ranked search results are swapped to produce re-ranked search results.
