  • SOCIAL MEDIA IMPACT ASSESSMENT
    Publication number: 20140189000
    Abstract: 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.

    Abstract: Described herein are various technologies pertaining to identifying global outlier candidates from a relatively large collection of computer-readable objects in a distributed computing environment. The collection of computer-readable objects is partitioned into a plurality of sets of objects, and local outlier candidates are identified from each set of objects in the plurality of sets of objects. The local outlier candidates are updated through a hierarchical pairwise similarity analysis until global outlier candidates are identified. Thereafter, a pairwise similarity analysis is undertaken with respect to the global outlier candidates and the sets of objects in the plurality of sets of objects to identify true global outliers.
