Patent number: 8886649Abstract: A canopy clustering process merges at least one set of multiple single-center canopies together into a merged multi-center canopy. Multi-center canopies, as well as the single-center canopies, can then be used to partition data objects in a dataset. The multi-center canopies allow a canopy assignment condition constraint to be relaxed without risk of leaving any data objects in a dataset outside of all canopies. Approximate distance calculations can be used as similarity metrics to define and merge canopies and to assign data objects to canopies. In one implementation, a distance between a data object and a canopy is represented as the minimum of the distances between the data object and each center of a canopy (whether merged or unmerged), and the distance between two canopies is represented as the minimum of the distances for each pairing of the center(s) in one canopy and the center(s) in the other canopy.Type: GrantFiled: March 19, 2012Date of Patent: November 11, 2014Assignee: Microsoft CorporationInventors: Xiong Zhang, Danny Lange, Hung-Chih Yang

Publication number: 20140189000Abstract: A system for identifying influential users of a social network platform. The system may compute a score for each of multiple users. Such a score may be topic-based, leading to a more accurate identification of influential users. Such a topic-based score may indicate authority and/or impact of a user with respect to a topic. The impact may be computed based on authority combined with other factors, such as power of the user. The authority score may be simply computed, in whole or in part, directly from a tweet log without, for example creating a retweet graph. As a result, the scores may be computed, using MapReduce primitives or other constructs that allow the computations to be distributed across multiple parallel processors. Such scores may be used to select users based on impact as part of social trend analysis, marketing or other functions.Type: ApplicationFiled: January 2, 2013Publication date: July 3, 2014Applicant: MICROSOFT CORPORATIONInventors: Xiong Zhang, Hung-Chih Yang, Danny B. Lange, Scott J. Counts, David M. Moore, Graham A. Wheeler, Bhalchandra Pandit
