Patent number: 9542441Abstract: The specification relates to a method of receiving a first query and a second query. The method analyzes the second query for a presence of anaphora. If anaphora is present, the method analyzes the first query for a presence of an entity that can be associated with the anaphora. If the analysis analyzing the first query returns two or more associated entities, the method forms a third query wherein the anaphora of the second query is replaced with one of the associated entities and forms a fourth query wherein the anaphora is replaced with the other of the associated entities. The third query and the fourth query are sent to a query-ranking engine. The third query and the fourth query receive a ranking and the higher-ranked query is sent to a search engine.Type: GrantFiled: November 6, 2015Date of Patent: January 10, 2017Assignee: Google Inc.Inventors: Michael Buchanan, Mark Andrew Paskin, Pravir Kumar Gupta
