Expedition of the Thousand 0

I’ve been through a crazy day at the Telecom Italia “Working Capital Initiative” event in Torino. Dressed in red like one the thousand we made a short presentation of the research projects funded last year (SIGSNA project was among those).  A new year of funding activity has started and – based on our SIGSNA experience […]

#senonoraquando 0

On Feb. 13th more than one million of Italian women and men gathered together in many Italian cities to protest over Berlusconi and to show their indignation provoked by Berlusconi’s recent sexual scandals. These are few data extracted from the tweets collected (via twapperkeeper) using the official #senonoraquando hashtag. PS: The small number of collected […]

Gender and Social Network Sites in Italy 0

Recently LaRiCA Lab released some very interesting data about News Consumption in Italy. The research mirrors a Pew Internet research made in the US in 2010 and offers several interesting opportunities for comparative analysis. In addition to that all the data have been made public using a creative commons license so you can just download the whole SPSS dataset and make you own analysis.

What are we studying? 0

While recently our Minister of Education described the Communication Studies as “nice but useless” Henry Jenkins made a point writing about the Future of Media Education. I think we all should start from here:

Visualising Italian FriendFeed Network 0

Recently we’ve posted on Friendfeed a visualisation of Italian Friendfeed users extracted from the data we’ve collected in 2009. Since the map started an interesting debate (you can read it here – in Italian -) we thought to write a short post explaining how the map has been done and what are its limits and possibilities.

The map is based on a network made of 8024 nodes with 244542 edges (even if the map shows only the nodes with more than 147 followers but statistical values have been counted on the whole network).

[SIGSNA] Mapping #UKge2010 0

Few days ago Axle Burns and the people from “Mapping online publics” posted a very interesting article about mapping the Australian election following #ausvote tweets. The idea behind that was rather good and simple: by mapping all the messages containing the conventional reply symbol (@username) one could map the conversational network surrounding a specific topic (defined by the #hashtag). Of course this methods has some limitations (clearly explained by Axle), nevertheless it can be use to produce a rough map of the conversational network.

Since some time ago we’ve downloaded (using Twapperkeeper – the same service used by Axel) all the tweets with the hashtag #ukge2010 (the “official” hashtag about Uk general elections) we have decided to do the same analysis on Uk tweets.
