Indiana University has announced a new website -- Truthy.indiana.edu -- which can be used to identify smear tactics and Twitter-bombs in advance of the upcoming November elections. This new Twitter-based research tool combines data mining, social network analysis and crowdsourcing to uncover deceptive political tactics and misinformation.
The application works by sifting through thousands of tweets per hour in search of political keywords. Then a team from IU's School of Informatics and Computing hones in on patterns of interest and inserts their findings -- called memes, indicating a pattern passed by imitation -- into Twitter's application programming interface (API) to obtain more information.
Filippo Menczer, an associate professor of computer science and informatics, explains further:
"When we identify a trend we go back and examine how it was started, where the main injection points were, and any associated memes. When we drill down we'll be able to see statistics and visualizations relating to tweets that mention the meme and basically reconstruct its history."
The site will help pinpoint dishonest motives, for example an astroturfing campaign, where special interest agendas are disguised as grassroots movement, or Twitter bombs, which can artificially inflate Google results.
The term "truthy" was popularized by political pundit Stephen Colbert in 2005 to indicate the use of emotional appeal as fact.

In quieter times, sounding the bell of funding big science with big systems tends to resonate further than when ears are already burning with sour economic and national security news. For exascale's future, however, the time could be ripe to instill some sense of urgency....
In a recent solicitation, the NSF laid out needs for furthering its scientific and engineering infrastructure with new tools to go beyond top performance, Having already delivered systems like Stampede and Blue Waters, they're turning an eye to solving data-intensive challenges. We spoke with the agency's Irene Qualters and Barry Schneider about..
Large-scale, worldwide scientific initiatives rely on some cloud-based system to both coordinate efforts and manage computational efforts at peak times that cannot be contained within the combined in-house HPC resources. Last week at Google I/O, Brookhaven National Lab’s Sergey Panitkin discussed the role of the Google Compute Engine in providing computational support to ATLAS, a detector of high-energy particles at the Large Hadron Collider (LHC).
05/10/2013 | Cleversafe, Cray, DDN, NetApp, & Panasas | From Wall Street to Hollywood, drug discovery to homeland security, companies and organizations of all sizes and stripes are coming face to face with the challenges – and opportunities – afforded by Big Data. Before anyone can utilize these extraordinary data repositories, however, they must first harness and manage their data stores, and do so utilizing technologies that underscore affordability, security, and scalability.
