ABSTRACT
Online Social Networks (OSN) are virtual environments that allow users to exchange messages, interact, and share content. The amount of information flowing through OSN promotes the competition for attention and influence among users who struggle to co-opt other users to share their message. The influence gained by users can be important to call the attention to target topics so that they eventually become Trend Topics (most popular topics within a time frame). In this work, we illustrate how we can apply concepts of network science to analyze the network structure that represents a Trend Topic. As a consequence, we show how to identify important users that contributed significantly to the topic popularity. In addition, we show how we can detect naive artificial efforts, such as bot activities, to increase the popularity of a user and, consequently, the popularity of the topic.

Discovering users' topics of interest on twitter: a first look
AND '10: Proceedings of the fourth workshop on Analytics for noisy unstructured text dataTwitter, a micro-blogging service, provides users with a framework for writing brief, often-noisy postings about their lives. These posts are called "Tweets." In this paper we present early results on discovering Twitter users' topics of interest by ...
