Patent number: 11468471Abstract: Systems and methods are presented for carrying out a task to an expanded group of users on behalf of a third party. In operation, an online service receives task information corresponding to a task from a third party. Additionally, the online service receives a seed group of users from the third party. The online service determines an intersection between the seed group of users and the online service's corpus of users. This intersection of users is then used to identify an expanded set of users of the online service's corpus of users. The online service then carries out the task on behalf of the third party, targeting the expanded set of users.Type: GrantFiled: February 8, 2019Date of Patent: October 11, 2022Assignee: Pinterest, Inc.Inventors: Stephanie deWet, Mukund Narasimhan, Jiafan Ou, Jian Huang

Patent number: 9794423Abstract: Described is a technology by which a user hums, sings or otherwise plays a user-provided rendition of a ringtone (or ringback tone) through a mobile telephone to a ringtone search service (e.g., a WAP, interactive voice response or SMS-based search platform). The service matches features of the user's rendition against features of actual ringtones to determine one or more matching candidate ringtones for downloading. Features may include pitch contours (up or down), pitch intervals and durations of notes. Matching candidates may be ranked based on the determined similarity, possibly in conjunction with weighting criterion such as the popularity of the ringtone and/or the importance of the matched part. The candidate set may be augmented with other ringtones independent of the matching, such as the most popular ones downloaded by other users, ringtones from similar artists, and so forth.Type: GrantFiled: June 15, 2016Date of Patent: October 17, 2017Assignee: MICROSOFT TECHNOLOGY LICENSING, LLCInventors: Lie Lu, Yutao Xie, Xing Xie, Jiafan Ou, Ruihao Weng
