Jocelyn Workman on 25 Mar 12Vieweg, S., Hughes, A., Starbird, K & Palen, L. (2010). Microblogging During Two Natural Hazards Events: What Twitter May Contribute to Situational Awareness. Retrieved 15 March 2012 from http://www.cs.colorado.edu/~palen/vieweg_1700_chi2010.pdf Individuals affected by the emergency events of the Red River Floods and the Oklahoma Grassfires in North America during the Spring of 2009, posted information about their respective situations via the microblogging service, Twitter. In this study, the authors analyse "situational update" information tweeted by individuals experiencing these hazards 'on the ground' to see how these people used the tweets to inform and develop an awareness of the current situation within their community. Twitter is seen as a commonly used social tool increasingly used for emergency communications "because of its growing ubiquity, communication rapidity, and cross platform accessibility", and are "a place for "harvesting" information during a crisis event to determine what is happening on the ground". From the analysis of collected data, coding was allocated by geo-location, location referencing and situational update information. Findings indicated Tweeters broadcasted similar types of information in both emergency situations, and tweets of high Tweeterers during emergencies were 'content rich' and displayed 'big picture situational awareness', with retweets indicating important updates. This study confirms how individuals facing a crisis rely on social media for their own safety and use the tool for altruistic purposes by providing current awareness of the crisis. In addition, the authors developed a Microblog-Enhanced Situational Features for Emergency outline of information categories for use in emergency response. They suggest this outline be used to assist with the development of system s

ruenhongo on 02 Apr 12This article relates to the article by Sutton (2010) because it talks about how micro-blogging in the time of disasters is one of the easiest ways for individuals to retrieve, produce and spread information through social networking sites such as Twitter. Sutton (2010) states that Twitter can bring people together in disasters which not only prompts micro-blogging but also can involve micro-volunteering as well. Online communities such as Twitter are decentralized which brings about self-organization and mobilization of information. The two articles are linked in that they both discuss how micro-blogging during disasters is about how information such as warnings, evacuations and peoples locations is shared online by different individuals in the community. Both articles had images implemented to show the readers where the location was that they were discussing as well as graphs to compare the data that is being focused. This made it very reliable to the topic and the range of references also showed how different perspectives were used in this research. I found the article relevant in showing how Twitter had an impact in disaster management and how micro-blogging can actually make a huge effect on how people communicate during a crisis. The graphs and images in the article were very useful because that provided evidence which complemented the text. The article is very valuable for this project because it shows how Twitter is evolving from being used for just a social medium to disaster management. References: Sutton, N. J. (2010).
