Katie Collins covers part of our work in Social Computing and Social Innovation at QCRI:

On 24 September a 7.7-magnitude earthquake struck south-west Pakistan, killing at least 300 people. The following day Patrick Meier at the Qatar Computer Research Institute (QCRI) received a call from the UN Office for the Coordination of Humanitarian Affairs (OCHA) asking him to help deal with the digital fallout -- the thousands of tweets, photos and videos that were being posted on the web containing potentially valuable information about the disaster.

[...] AIDR (Artificial Intelligence for Disaster Response) was the second project tested for the first time during the Pakistan floods, and is due to be launched officially at the CrisisMappers conference in Nairobi in November. It's an open-source tool relying on both human and machine computing, allowing human users to train algorithms to automatically classify tweets and determine whether or not they are relevant to a particular disaster.

In Pakistan, SBTF volunteers tagged 1,000 tweets, out of which 130 were used to create a classifier and train an algorithm that could be used to recognise relevant tweets with up to 80 percent accuracy ...

QCRI/AJE press release: QCRI and Al Jazeera launch predictive web analytics platform for news

New platform developed by QCRI and Al Jazeera can predict visits to news articles by taking cues from social media

News organisations have vast archives of information, as well as a number of web analytic tools that aid in allocating editorial resources to cover different news events, and capitalise on this information. These tools allow editors and media managers to react to shifts in their audience’s interest, but what is lacking is a tool to help predict such shifts.

Qatar Computing Research Institute (QCRI) and Al Jazeera are announcing the launch of FAST (Forecast and Analytics of Social Media and Traffic), a platform that analyses in real-time the life cycle of news stories on the web and social media, and provides predictive analytics that gauge audience interest.

“The explosion of big data in the media domain has provided QCRI an excellent research opportunity to develop an innovative way to derive value from the information,” said Dr Ahmed Elmagarmid, Executive Director of QCRI. “Together with our valued partner, Al Jazeera, the QCRI team has developed a platform that will help shift the way media does business.”

“Al Jazeera English’s website thrives on good original content in news and features, dynamic ways of creativity through interactive and crowd sourcing methods, and up-to-date social media tools. We welcome working with QCRI in developing FAST as it allows us to understand the consumption of news and what is expected to do well in driving traffic forward. Analytics in predicting the future trend of a web story is a crucial component in understanding web traffic, this initiative is a component we welcome,” said Imad Musa, Head of Online for Al Jazeera English.

You can test the platform at http://fast.qcri.org/ and read the full press release at the QCRI website. The system is based on research described in the following paper:

• Carlos Castillo, Mohammed El-Haddad, Jürgen Pfeffer and Matt Stempeck: Characterizing the Life Cycle of Online News Stories Using Social Media Reactions. Submitted for publication. [arxiv pre-print|review by s.v.]

With Janette Lehmann (UPF), Mounia Lalmas (Yahoo!) and Ethan Zuckerman (MIT Civic Media), we developed an automatic method (pdf, blog post) that groups together all the users who tweet a particular news item, and later detects new contents posted by them that are related to the original news item.

We call each such group a transient news crowd. The beauty of this approach, in addition to being fully automatic, is that there is no need to pre-define topics and the crowd becomes available immediately, allowing journalists to cover news beats incorporating the shifts of interest of their audiences.

Congratulations to my colleagues M. Imran (QCRI), S. Elbassuoni (Beirut University), F. Diaz (Microsoft) and P. Meier (QCRI) for a best paper award at the ISCRAM conference. ISCRAM is the main international conference on systems for crisis response and management.

Our work, described in the two papers below (specially on the first one), describes a method to extract information nuggets from tweets related to emergencies. For instance, we can go beyond detecting that a tweet is about a donation to identify which is the item being donated (e.g. clothes, money, etc.).
