  1. CTRnet (Crisis, Tragedy, & Recovery Network)(www.ctrnet.net):A global human network and distributed digital library Edward Fox (fox@vt.edu), BidishaDewanjee, Andrea Kavanaugh, Uma Murthy, Naren Ramakrishnan, Steven Sheetz, Donald Shoemaker, and VenkataraghavanSrinivasan (+CS5604F09 team) Oct. 29, 2009 -- University of Iowa http://fox.cs.vt.edu/talks/2009/20091029IowaCTRnet.pptx Departments: Accounting Information Systems Computer Science Sociology Grant: IIS-0916733

  2. Outline • Introduction • Collection, Communities • Architecture, Services • Development Approach, Focus Groups, Ontology, Web 2.0 • Priorities, Research Questions • Discussion

  3. Thanks to: NSF IIS-0736055

  4. Broader Interest • Kauhajoki Finland shooting • Northern Illinois U. shooting • Texas A&M Bonfire disaster (Project BEAM) • Beslan school massacre • Requests for help with documentaries • MoU with eIFL.net? • Interest: counseling, psychology, sociology, history, oral history, technology use, … • Idea: distributed digital library network, with world-wide collaborating community

  5. Purpose / Vision • In the context of crises and tragedies • and long-term community recovery (CTR) • support domain specific needs • of diverse stakeholder groups • through intelligent information integration • and rich digital library services

  6. Broad Project Research Questions • How can a portion of the CTR Network be built semi-automatically, drawing upon related digital libraries, web pages, query logs, Web 2.0 applications, and other readily available Internet resources? • How can this CTR Network be utilized, efficiently and effectively, for a wide variety of tasks? • What kind of (usable) user interfaces can facilitate building and utilizing the CTR Network? • How can our solution be evaluated and validated, leading to a widely used methodology?

  7. Crisis, Tragedy, and Recovery • Human tragedies that result from man-made and natural events affect communities significantly. • During and after a tragic event, there are a series of needs that have to be addressed. • Usually connected with communication and a confusing plethora of data and information

  8. Limited Data & Information on CTR Staging: school shootings, school events, then to full set of natural / man-made

  9. Data Collection • Expand coverage at Internet Archive • Can crawl about 17million URLs a year • Can get data back from them twice yearly • Now crawling re Typhoons in Asia-Pacific (e.g., Ketsana), and about schools • Archive-It tool (http://archive-it.org) • Can select seeds (starting URLs) • Various parameters to adjust coverage • Seek volunteers to spot events, give seeds

  10. Data Collection Challenges • How to improve precision of crawls? • How to automate generation of high quality seeds, across genre & topics? • Ensuring balance, without bias • How to automate generation of filters that will further improve collections? • How to ensure security and privacy while facilitating research? • (above are some of student studies …)

  11. Build a networked digital library relating to CTR • Integrate community, content, and services relating to CTR, making it accessible, and preserving it for long-term reuse • Support information exploration • Aided by an ontology

  12. CTR stakeholders

  13. Services

  14. SSP1and Storytelling 1 Stepping Stones and Pathways, http://fox.cs.vt.edu/SSP

  15. Potential impact • Help affected communities to recover more quickly and effectively • Global network • Easy accessibility • Relevant information and resources and services • Support classes of stakeholders in reacting to and recovering from crises • Researchers • Scholars • Emergency personnel • Decision makers • Public

  16. Development Approach • Interactions with Users • Stakeholders • Focus Groups • Survey • Ontology Evaluation • Automated Discovery • N-Gram evaluation of ISCRAM Proceedings • Related research from other disciplines • Review of Literature and Existing Systems • Incident Report Database Schema • Integration of multiple literatures

  17. Focus Group Question Thinking of your research interests and of the interests of other researchers in your discipline: 1) What are the most important research questions, issues, and/or concepts that are relevant to the events of April 16th? 2) What data are needed to address these research questions and issues? 3) What are ideal visualizations that would be most useful for understanding the key issues in your discipline.

  18. Categories from focus group study Results from focus group interviews following the April 16, 2007 tragedy at Virginia Tech

  19. CTR keyword pairs Extracted top keyword pairs from ISCRAM proceedings using the N-gram statistics package

  20. Browsing CTR literature • Searching • Query • expansion Focus groups CTR Ontology • Individual • Organizational • Community • Political • … Tagging Websites, Internet Archive Recommending Summarizing Visualizing Multicultural/ linguistic input Goals for Ontology for CTR sources Social network applications uses

  21. Why social networking websites on 416? • If you used a social networking website to communicate to others that you were safe or OK, which website did you use first? (identify the website, then briefly - 1 or 2 sentences/phrases - explain why you selected this website) • 426 responses • Content Analysis • Results

  22. Why use Facebook?

  23. Frequency of Keyword Occurrence

  24. Keyword Co-Occurrence

  25. Next Steps • Users • Select Next Stakeholder Group • Focus Groups • Automated Discovery • Apply N-Gram evaluation to Sociology Research • Revise Ontology • Examine multiple arrangements • Evaluate usefulness with crawl results

  26. Outreach • CTRnet website • Forums, user submission uploads, … • Feedback/Feature requests/suggestions • Collaborative spotting and seeding • CiteULike (http://www.citeulike.org) • Group called “ctrnet” • Please join - and post pointers to papers, books, and other scholarly materials

  27. Priorities • Find more partners (including internationally: Finland, Mexico, Russia, …) • Storytelling with data in hand re VT, NIU Using social/behavioral science research questions • Crawl locally and at IA, filter, train others • Collect large amount of information, initially especially related to schools worldwide • Plan CTR computer: Key tools, Key content • Initial release, for public and researchers:

  28. Research Questions - sample An important goal of the CTRnet project is to provide assistance to researchers, especially from social / behavioral science fields. Listed below are a few research questions which are connected with school shootings and similar tragedies. 1. What are the social parameters of social networking (such as Facebook and Myspace) in reaction to school tragedies? For example, do women use social networking more often than men? Is social networking more common among students than faculty or staff? Is social networking more common among university personnel than within the community? •  (cont’d)

  29. Research Questions - continued 2. How do school structures affect responses to tragedies? What is the impact of tragedies on community structures and school-community relationships? 3. Are there stages of grieving within a community? We know people go through several stages of grief in reaction to the loss of loved ones. Do communities also go through stages of grief in reaction to tragedies? 4. What are the characteristics of school administrations in reaction to tragedies? For example, do schools vary in initial reactions to tragedies, such as communication and class schedules? Are there differences with regards to long-term effects of tragedies, in terms of organization and communication systems? 5. Are there international differences in response to school shootings? Are these differences evident in school and community settings?

  30. Questions for U. of Iowa(from Amine Chigani) • How was the communication among all those involved coordinated during the immediate emergency response efforts to the flood incident? (Email, cell phones, website, TV, Text Messages, Social Networks, Sirens, etc.) • Were there any modes of communication failure or breakdown between emergency response person-nel (police, first responders, etc.) and the public? • In retrospect, what kind of processes, systems and/or technologies would have been nice to have to respond more effectively and efficiently to the incident?

  31. Discussion Questions • More research questions, requirements? • Other people, partners, collaborators, sponsors? • Should we run more focus groups? • Pointers to • papers, classes, case studies, publications? • Ontology • What should it contain? • How can it be enhanced and validated? • CTR toolkit? Services? …
