Patent number: 9881037Abstract: A system for determining a canonical title includes an interface and a processor. The interface is to receive a new title. The processor is to generate a set of n-grams based on the new title; look up n-grams in canonical database to assign one or more labels; and map the new title to a canonical title based on the one or more labels.Type: GrantFiled: April 14, 2016Date of Patent: January 30, 2018Assignee: Workday, Inc.Inventors: Vladimir Giverts, Jonathan Goldman, Adeyemi Ajao, Barzel Segal, Phil Monroe, Kristy Gateley, Jan Prach, Tarek Rabbani, Efraim Feinstein, Anuranjita Tewary, Lucian Lita

Patent number: 9366886Abstract: An optical switch includes a microresonator comprising a silicon-rich silicon oxide layer and a plurality of silicon nanoparticles within the silicon-rich silicon oxide layer. The microresonator further includes an optical coupler optically coupled to the microresonator and configured to be optically coupled to a signal source. The microresonator is configured to receive signal light having a signal wavelength, and at least a portion of the microresonator is responsive to the signal light by undergoing a refractive index change at the signal wavelength. The optical switch further includes an optical coupler optically coupled to the microresonator and configured to be optically coupled to a signal source. The optical coupler transmits the signal light from the signal source to the microresonator.Type: GrantFiled: July 31, 2014Date of Patent: June 14, 2016Assignee: The Board of Trustees of the Leland Stanford Junior UniversityInventors: Michel J.

Patent number: 9342592Abstract: A method for normalizing raw titles to canonical titles is described. The method includes designating a set of canonical titles, generating a set of n-grams for each canonical title, assigning a set of attributes to each n-gram, assigning a set of labels to each of the attributes, and storing the labeled canonical title and labeled n-grams in a database. In some examples, a new title may be mapped to an existing canonical title in the database by generating a set of n-grams for the new title, looking up the n-grams in the database of canonical titles, retrieving the set of labels assigned to n-grams in the database that match n-grams from the new title, and assigning those labels to the corresponding attributes of the new title. The new title may then be mapped to a canonical title on the basis of similarly labeled attributes.Type: GrantFiled: July 29, 2013Date of Patent: May 17, 2016Assignee: Workday, Inc.Inventors: Vladimir Giverts, Jonathan Goldman, Adeyemi Ajao, Barzel Segal, Phil Monroe, Kristy Gateley, Jan Prach, Tarek Rabbani, Efraim Feinstein, Anuranjita Tewary, Lucian Lita

Publication number: 20160057496Abstract: Content recommendations are described. In an implementation, feedback collected from a user is used to determine favored characteristics of particular items of musical content. One or more other items of content, which are not music, are identified that correspond to the favored characteristics. The identified one or more other items of content are recommended to the user.Type: ApplicationFiled: July 27, 2015Publication date: February 25, 2016Inventors: Anuranjita Tewary, Jonathan L. Conradt
