Abstract
The blogosphere is changing how people experience war and conflict. We conducted an analysis of 125 blogs written by Iraqi citizens experiencing extreme disruption in their country. We used Hoffman's [8] stages of recovery model to understand how blogs support people in a region where conflict is occurring. We found that blogs create a safe virtual environment where people could interact, free of the violence in the physical environment and of the strict social norms of their changing society in wartime. ...

Abstract
We analyze microblog posts generated during two recent, concurrent emergency events in North America via Twitter, a popular microblogging service. We focus on communications broadcast by people who were "on the ground" during the Oklahoma Grassfires of April 2009 and the Red River Floods that occurred in March and April 2009, and identify information that may contribute to enhancing situational awareness (SA). This work aims to inform next steps for extracting useful, relevant information during emergencies using information extraction (IE) techniques. ...

Abstract
This empirical study of "digital volunteers" in the aftermath of the January 12, 2010 Haiti earthquake describes their behaviors and mechanisms of self-organizing in the information space of a microblogging environment, where collaborators were newly found and distributed across continents. The paper explores the motivations, resources, activities and products of digital volunteers. It describes how seemingly small features of the technical environment offered structure for self-organizing, while considering how the social-technical milieu enabled individual capacities and collective action. Using social theory ...

Abstract
Seasonal influenza epidemics are a major public health concern, causing tens of millions of respiratory illnesses and 250,000 to 500,000 deaths worldwide each year. In addition to seasonal influenza, a new strain of influenza virus against which no previous immunity exists and that demonstrates human-to-human transmission could result in a pandemic with millions of fatalities. Early detection of disease activity, when followed by a rapid ...

Abstract
Web logs (or blogs) have become a means for citizens to share opinions and deliberate on local issues. However, the large number of blogs makes finding and exploring content of interest relatively difficult. This discovery problem presumably also limits participation by interested citizens. We present a tool to display a representation of citizen-to-citizen discussion in blogs that reveals similarity across blog entries. Through association and content analysis, blog entries are linked to each other to form clusters of related local content. ...

Abstract
There may be limited resources for local government Web site designers to devote to innovative design. This study investigated current technology use by local government (Town of Blacksburg, TOE - Virginia) and suggests key design guidelines. Observation and interviews were used. Using recommendations in phase I, the TOE employed a blog that was investigated in phase II. The TOE incorporated traditional media with online to broadcast public meetings via TV and online. We suggested using indexed video to improve usability by ...

Abstract
Broad and diverse civic participation is essential to a democratic society. Studies of opinion leadership show that politically active citizens report that Internet information and communication helped increase civic involvement by enabling them to keep up more easily with news, interact with fellow citizens or engage in collective action. Yet information about less active citizens remains scant. Does the Internet influence the politically passive majority of citizens to become more involved in political talk or other forms of participation? Do they ...

Abstract
Some local government officials and staff have been experimenting with emerging technologies as part of a broad suite of media used for informing and communicating with their constituencies. In addition to the typical government website and, for some, email exchange with citizens, some town and municipal governments are using blogs, video streaming, pod- casting, and Real Simple Syndication (RSS) to reach constituencies with updates and, in some cases, interaction and discussion between citizens and government. ...

Abstract
People use various modes of communication to maintain their social networks, both local and distant. In the United States, Internet use has been growing steadily, and electronic mail has consistently been the most popular online activity. We investigate the effect of online communication with social ties in the highly networked community of Blacksburg, VA, and surrounding rural Montgomery County. We conducted a random strati- fied household survey to residents in two rounds (2001 and 2002) as part of a larger study ...

Abstract
This study explores the design and practice of the Blacksburg Electronic Village (BEV), a mature networked community. We describe findings from longitudinal survey data on the use and social impact of community computer networking. The survey data show that increased involvement with people, issues and community since going online is explained by education, extroversion and age. Using path models, we show that a person's sense of belonging and collective efficacy, group memberships, activism and social use of the Internet act as ...

Abstract
A community computer network facilitates civic participation by providing pervasive local resources online and by connecting people to local communication and discussion channels, public and non-profit organization leaders and members, and many other civic resources. We present findings from longitudinal data (two rounds between 2001 and 2002) of a stratified random survey of 100 households in a mature community network, the Blacksburg Electronic Village (BEV). We offer exploratory and confirmatory analyses, including a ‘civic effects’ model, that show demographic characteristics (education, ...

Abstract
Communities respond to tragedy by making virtuous use of social networking sites for a variety of purposes. We asked students to describe why they used a social networking site after the tragic shootings at Virginia Tech, then evaluated their responses using content analysis. Students went predominately to Facebook (99%). Most (59%) of the 426 students that responded went there because their friends were already there, and to find out if their friends were OK (28%) (and to let them know they were OK). Ideas related ...

No. TR-11-10. (07 July 2011)
Abstract
In this paper we examine the use of social media, and especially Twitter, in Iran, Tunisia and Egypt during the mass political demonstrations and protests in June 2009, December 2010 - January 2011, and February 2011, respectively. We compare this usage with methods and findings from other studies on the use of Twitter in emergency situations, such as natural and man-made disasters. We draw on our own experiences and participant-observations as an eyewitness in Iran (first author), and on Twitter data ...

Abstract
This tutorial introduces various open source tools and methods to archive tweets on a user's local machine and convert them into topic clouds for quick content analysis. For more in-depth analysis of the content, basic natural language processing techniques such as n-grams and term extraction are introduced along with PHP/Python scripting. ...

Abstract
This poster presents one of our efforts in the context of the Crisis, Tragedy, and Recovery Network (CTRnet) project. One topic studied in this project is the use of social media by government to respond to emergency events in towns and counties. Monitoring social media information for unusual behavior can help identify these events once we can characterize their patterns. As an example, we analyzed the campus shooting in the University of Texas, Austin, on September 28, 2010. In order to ...

Abstract
Social media (i.e., Twitter, Facebook, Flickr, YouTube) and other services with user-generated content have made a staggering amount of information (and misinformation) available. Government officials seek to leverage these resources to improve services and communication with citizens. Yet, the sheer volume of social data streams generates substantial noise that must be filtered. Nonetheless, potential exists to identify issues in real time, such that emergency management can monitor and respond to issues concerning public safety. By detecting meaningful patterns and trends in ...

Abstract
Event-Based Epidemic Intelligence (e-EI) has arisen as a body of work which relies upon different forms of pattern recognition in order to detect the disease reporting events from unstructured text that is present on the Web. Current supervised approaches to e-EI suffer both from high initial and high maintenance costs, due to the need to manually label examples to train and update a classifier for detecting disease reporting events in dynamic information sources, such as blogs. In this paper, we propose ...
