Destination Area: Data and Decisions (D&D)
Permanent URI for this collection
The DA Data and Decisions advances the human condition and society with better decisions through data. D&D integrates all DAs and SGAs with data analytics and decision sciences. Work in this area embraces equity in the human condition by seeking the equitable distribution and availability of physical safety and well-being, psychological well-being, respect for human dignity, and access to crucial material and social resources throughout the world’s diverse communities. D&D also addresses policymaking and policy analysis, collaborating at the intersection of scientific evidence, governance, and analyses to translate scholarship into practice.

- Crisis, Tragedy, and Recovery Network (CTRnet)Fox, Edward A. (2009-09-14)This poster provides an overview of the Crisis, Tragedy, and Recovery Network (CTRnet). The objectives of CTRnet are to build a digital library and preserve information (in various formats like HTML, images, videos, etc.) relating to all kinds of community crises and tragedies, as well as to integrate communities, content, and services relating to CTR.
- Crisis, Tragedy, and Recovery Network Digital Library (CTRnet)Chitturi, Kiran; Fox, Edward A. (2013-01-10)This presentation outlines the goals of the Crisis, Tragedy and Recovery Network (CTRnet) project. These goals include researching the problems of integrating content, community, services related to crisis, tragedies, and recovery; integrating heterogeneous information in a specific domain, making it accessible, and preserving it for long-term reuse; extending the scope of digital libraries so they are closely but flexibly coupled with a wide variety of services to support diverse emerging communities; and supporting information exploration with advanced methods (Stepping Stones and Pathways (SSP), PathRank, and Storytelling) that facilitate searching, browsing, and discovery.
- Crisis, Tragedy, and Recovery Network Digital Library (CTRnet) + Web Archiving in Qatar and VTFox, Edward A.; Yang, Seungwon; CTRnet Team (2013-07-01)This presentation describes the Crisis, Tragedy, and Recovery Network's digital library development and web archiving activities in Qatar and Virginia Tech. The presentation covers project goals, archiving tasks, dissemination efforts, and the IDEAL project.
- CTRnet Final ReportFox, Edward A.; Shoemaker, Donald J.; Sheetz, Steven D.; Kavanaugh, Andrea L.; Ramakrishnan, Naren (2013-08-26)The CTRnet project team has been developing a digital library including many webpage archives and tweet archives related to disasters, in collaboration with the Internet Archive. The goals of the CTRnet project are to provide such archived data sets for analysis, including by researchers who are seeking deep insights about those events, and to support a range of services and infrastructure regarding those tragic events for the various stakeholders and the general public, allowing them to study and learn.
- NSF 2nd Year Report: CTRnet: Integrated Digital Library Support for Crisis, Tragedy, and RecoveryFox, Edward A.; Shoemaker, Donald J.; Sheetz, Steven D.; Kavanaugh, Andrea L.; Ramakrishnan, Naren (2011-07-01)One of the important parts of this project is to collect and archive as much information as possible about various events that are related to crises, tragedies, and recovery (CTR). In order to do long-term archiving of information, we have worked with the Internet Archive (IA), a non-profit organization, whose goal is to archive the Internet. IA provides access to web crawlers that can be used to selectively crawl and archive webpages. In disaster situations, it is well known that people use micro-blogging sites such as Twitter to reach their family and friends especially when their cell phones are not working due to high volume of traffic on the cell phone network. For this reason, tweet posts sometimes report CTR events faster than the mainstream news media. Those tweets often contain more detailed information, too, reported by the affected people on the site. We have been archiving tweets (i.e., posts from Twitter.com) for both man-made and natural disaster events. Collected tweets can be exported in various formats including XSL, JSON, and HTML -- to be analyzed later using software tools.
- NSF 3rd Year Report: CTRnet: Integrated Digital Library Support for Crisis, Tragedy, and RecoveryFox, Edward A.; Shoemaker, Donald J.; Sheetz, Steven D.; Kavanaugh, Andrea L.; Ramakrishnan, Naren (2012-07-01)The Crisis, Tragedy and Recovery (CTR) network, or CTRnet, is a human and digital library network for providing a range of services relating to different kinds of tragic events, including broad collaborative studies related to Egypt, Tunisia, Mexico, and Arlington, Virginia. Through this digital library, we collect and archive different types of CTR related information, and apply advanced information analysis methods to this domain. It is hoped that services provided through CTRnet can help communities, as they heal and recover from tragic events. We have taken several major steps towards our goal of building a digital library for CTR events. Different strategies for collecting comprehensive information surrounding various CTR events have been explored, initially using school shooting events as a testbed. Many GBs worth of related data has been collected using the web crawling tools and methodologies we developed. Several different methods for removing non-relevant pages (noise) from the crawled data have been explored. A focused crawler is being developed with the aim of providing users the ability to build high quality collections for CTR events focused on their interests. Use of social media for CTRnet related research is being explored. Software to integrate the popular social networking site Facebook with the CTRnet digital library has been prototyped, and is being developed further. Integration of the popular micro-blogging site Twitter with the CTRnet digital library has proceeded well, and is being further automated, becoming a key part of our methodology.

- Twitter Use During an Emergency Event: The Case of UT Austin ShootingLi, Lin Tzy; Yang, Seungwon; Kavanaugh, Andrea L.; Fox, Edward A.; Sheetz, Steven D.; Shoemaker, Donald J. (2011-06-01)This poster presents one of our efforts developed in the context of Crisis, Tragedy, and Recovery Network (CTRnet) project. One of our derived works from 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 occurred in the University of Texas, Austin, on September 28, 2010. In order to study the pattern of communication and the information communicated using social media on that day, we collected publicly available data from Twitter. Collected tweets were analyzed and visualized using Natural Language Toolkit, word clouds, and graphs. They showed how news and posts related to this event swamped the discussions of other issues.
