SOCIAL MEDIA IMPACT ASSESSMENT

摘要

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.

1. A method of determining authority of a user of a social media platform, the method comprising:
with a plurality of processors:
processing a message log to compute, for each of a plurality of users, at least one topical metric; andprocessing the topical metrics to compute, for at least a portion of the plurality of users, a topical authority score indicative of the authority of the user, wherein, the topical authority scores are computed in terms of MapReduce primitives.
