Social Media play a critical role during crisis events, revealing a natural coordination dynamic. We propose a computational framework guided by social science principles to measure, analyze, and understand coordination among the different types of organizations and actors in crisis response. The analysis informs both the scientific account of cooperative behavior and the design of applications and protocols to support crisis management.

  • S-1, S-2: 1 (+half) minute - So, I’m going to talk about our view point on coordination --- it’s context, actors involved, potential methods to detect and our framework finally – initial results and tool – Twitris+
  • - 1 (+half) minute Alright, so let’s motivate by this situation during emergency - Various actors: resource seekers, responder teams, resource providers at remote site And - each of these actor groups have questions --- - needs - providers - responders: wondering! Here we have social network to connect these actors and bridge the gap for communication platform But it’s potential use is yet to be realized for effective help Because.. (next slide questions)
  • Definition of coordination says ‘harmonious functioning of parts’, but here missing thing is the CONTEXT In the current context it means well coordinated actions for emergency response needs and we have got pretty good set of challenges here to realize the goal of such harmonious functioning!
  • Lesson learned: We need to better understand how to tap the maximum potential of local/informal communities
  • Here are the types of organizations, from which various actors participate for the goal of coordinated actions for response needs We categorize them based on ‘ structure for command and communication’ examples:- ( http://www.disastercenter.com/agency.htm )
  • Natural Liguistics patterns: What types of words they use, - What type of functional language usage It seems that formal organizations' raison d'être  is to serve the needs of the informal organizations, the users. Meanwhile the users' understanding and investment in the formal organizations verges on the obscure. Therefore it makes more sense to alter the behavior of the former, not the latter, by using method 'B’
  • - Talk about what has been implemented already and what is under progress
  • Here we present our analysis phases: Data collection, aggregation, filtering, Candidate sets preparation for coordination, detection of coordination behavior and summarization deixis refers to the phenomenon wherein understanding the meaning of certain words and phrases in an utterance requires contextual information Anaphora is an instance of an expression referring to another

    • 1. Coordination Analysis Framework for Emergency Response Feb 11, 2012 Collaboration and Crisis Informatics, CSCW-2012 H. Purohit, A. Hampton, V. Shalin, A. Sheth, J. Flach Ohio Center of Excellence in Knowledge-enabled Computing ( Kno.e.sis ) Wright State University, OH, USA Publication: http://knoesis.wright.edu/library/resource.php?id=1640
    • 2. Outline
      • Motivation
      • Coordination in context
      • Types of participating organizations
      • Potential methods for analysis
      • Analysis Framework
      • Analysis phases and preliminary results
      • Scalability for Real-time Performance
      • Online system in development
        • Twitris+ ( http://twitris.knoesis.org )
    • 3. wish i could help #tsunami what can i do for these people? #japanearthquake @clancycnn #WFP #Japan Milk for children is so needed right now, there's no milk in some stores & that shortage may be the worse. RT @ietweet: Japan's tsunami-ravaged hospitals run out of food, medicines : http://goo.gl/natY3
    • 4. The Coordination Challenge
      • How can emergency responders determine greatest need?
      • Who in the informal community on social-net can help?
      • Which people should be sent where?
      • What can remote outsiders do?
      • How can someone solicit help when emergency services are overwhelmed?
      Coordination in Dictionary: “the harmonious functioning of parts for effective results”
    • 5. An excerpt
      • Address by Commander of Joint Task Force Katrina, Lt. Gen. Russel L. Honoré (Ret.) at Wright State, Feb.1,2012 :
      “ .. the biggest helping hand comes from people in the local communities, they have resources to share, and no Emergency Response storage can store the things to the scale which is needed during critical time .. ” Lesson Learned: Better understand the dynamics of various actors involved and especially, informal communities forming outside the periphery of responder teams!
    • 6. Types of Organizations Working Together  
        • Formal
          • FEMA, EMTs, Hospitals, Law Enforcement, Public Safety
        • Informal
          • Local Communities, Churches, Suppliers
        • Hybrids
          • Red Cross, DERA (Disaster Preparedness and Emergency Response Association)
        • Differing structures for command and communication exacerbate the coordination challenge.
    • 7. Potential Coordination Methods
      • Impose pre-structured communication protocol on the informal organization.   
            • Mine natural linguistic patterns in user interactions for formal organization needs.
              • Collect tweets
              • Detect coordination
              • Summarize for formal organization
    • 8. Framework for Coordination Analysis
    • 9. Analysis Phases * Grey color: Work In Progress, Orange: Experimented
    • 10. Preliminary Results
      • Discrimination metric for coordination indicative candidates: D-prime (values range from 0 to 1.25)
        • Promising heuristics
          • Pronouns, length of the candidate set
        • Degree of Discrimination
          • RT > Reply > @Addressee
        • Corpus Dependent
          • Possible Socio-Cultural Influence
        • Variation w.r.t. Decision Criterion in D-prime analysis
          • Examine distribution assumptions
        • Explore sophisticated heuristic combinations
          • Regression modeling to quantify degree of coordination
    • 11. Scalability and Impact in Real-Time
      • Current Analysis
        • 0.55M topical twitter posts
        • Events with varied social significance, spanning over different time periods
        • Parallel Computing paradigm for implementation
      • Work In progress
        • Current analysis done offline to build solid framework but objective is to bring it to near real-time and integrate with visualization tool to help emergency response teams
        • Twitris+ social analytics platform
    • 12. Twitris+: 360 0 Social Media Analysis Platform
      • Tool to aid emergency responders and situational awareness

        • People-content-network
        • Sentiment-emotion-subjectivity
        • Search-browsing etc.
