Hoy traemos a este espacio el Projeto Ecología Digital (que me ha recordao a un antiguo blog que abrimos en 2003 y que escribimos unos años Ecología de la Comunicación ) ...
Digital Ecology: emergence of Twitter's trending topics
Digital Ecology is a research project funded by the São Paulo State Research Foundation (FAPESP) and developed at the University of São Paulo. The project aims to explain the emergence of Trending Topics within Twitter mediascape.
Twitter is a micro-blogging service that allows users to publish and exchange short messages, also known as tweets, through a wide variety of clients. Since Twitter enables real-time propagation of information to any number of users, the platform is an ideal environment for the dissemination of breaking-news directly from the news source and/or geographical point of interest.
A re-tweet (RT) is a quote of another tweet, which may or may not include a comment or reply. Retweet activity reflects how the social network helps in the propagation of the information and shed some light on patterns of diffusion in digital networks, since an active social network promotes the steady dissemination of related messages.

The serious activism project is an attempt to understand how social media is changing grassroots movements. We believe that political activism has changed significantly from a representative, hierarchical, and party-based system towards a decentralized, horizontal, and network-based system.
While political activism has changed dramatically in the past years, politics continues to be played out at the institutional level. As researchers, we are fascinated by the ways people can be politically active without engaging or supporting multi-party democracy. This interest has been stoked by social movements like the Indignados, Occupy, and Gezi.
We started this project to investigate the number and diversity of Twitter users that participated in multiple political hashtags in the past five years (2009-2013). We looked at a group of 150 political hashtags to examine the activity levels and the overlapping of users across multiple protests.
Political activists rely on word of mouth to spread their messages. Traditionally, these were channelled through personal relationships. By contrast, we are finding that the number of retweets between users that do not follow each other is consistently higher than retweets between reciprocally connected users. (...)
Platform T: a robust and flexible technology for Twitter analysis
We created the Platform T to perform a robust, flexible and customizable analysis of Twitter content. Platform T is based upon several scripts mainly designed by Rodrigo Travitzki comprising the following computer implementations:
- PHP (dynamic internet);
- MySQL (database);
- R (statistical analysis).
The scripts work as a plug-in to the GNU/GPL software YourTwapperKeeper
and have been widely tested on UNIX systems (Linux and Mac OS).
Platform T collects, compares and tabulates Twitter data providing some basic exploratory analysis of each sample (tweets clustered by a keyword or hashtag). Platform T thus produces a variety of objects - tables, matrices and networks - that can subsequently be used for different uses and objectives.
What follows next is a diagram of the Platform T structure. It depicts the diversity of Twitter APIs used to cluster the required data and the general connection over Twitter, PHP, MySQL and R.
