Patent number: 11188601Abstract: Disclosed is a system comprising a computer-readable storage medium storing at least one program, and a computer-implemented method for generating search results. A data access module accesses search results data indicative of a plurality items and that is indicative of ranking values of the plurality of items. A controller module generates page data based on the search results data. The controller module selects a first item from the plurality of items. A diversification module accesses a first rule of the page data. The diversification module determines a deviance value and a reordering-cost value of a second item from the plurality of items. The controller module can select, based at least on a first combination of the deviance and the reordering-cost values of the second item, the second item for placement ahead of the first item on the page data.Type: GrantFiled: June 13, 2018Date of Patent: November 30, 2021Assignee: EBAY INC.Inventors: David Goldberg, Miroslav Melichar, Michael Ching, Davide Libenzi

Patent number: 10360621Abstract: Example embodiments described herein disclose systems and methods for near-identical multi-faceted entity identification within search results from an online marketplace. The online marketplace may be or include a group of one or more server machines configured to provide one or more online marketplace services, including the near-identical multi-faceted entity identification system. A user device may accordingly request and receive, from the online marketplace, a set of item listings based on submitted search criteria. The online marketplace may then access the set of item listings and identify one or more similar item listings among the set of item listings in order to demote a ranking of the similar item listings within the set.Type: GrantFiled: May 19, 2016Date of Patent: July 23, 2019Assignee: eBay Inc.Inventors: Vamsi Krishna Salaka, Marco Pennacchiotti, Davide Libenzi, Timothy Bethea

Patent number: 9081821Abstract: An input query can be spell checked by first parsing the input query into one or more tokens. The one or more tokens are then compared against spell storage tables to derive alternative tokens. A spell cursor is launched, with the spell cursor calculating scores for permutations of the tokens and alternative tokens, and the scores representing a likelihood that a user intended to use the permutation as the input query. A memory table may then be formed including the permutations and scores. The memory table can then be passed to a column cursor, the column cursor designed to form an output table of results based on queries to a database using the permutations.Type: GrantFiled: December 11, 2012Date of Patent: July 14, 2015Assignee: eBay Inc.Inventors: Guanglei Song, Anand Lakshminath, Nicholas Whyte, Prasad Sriram, Davide Libenzi
