The Internet & The Cloud - Socio-economic Impact on CitizensLSP / PSL
The cloud is affecting our lifes in a profound way. This presentation elaborates on three interconnected aspects: the loss of control of the citizen, the increasing censorship and the increasing surveillance. Given the recent disclosures, the presentation elaborates in particular on the NSA's PRISM surveillance program.
The case for integrating crisis response with social media American Red Cross
Social media has changed expectations around crisis response by allowing people to directly request help online. This has created challenges for emergency responders to monitor and respond to these requests in a timely manner. In response, volunteer groups have formed using technologies like Ushahidi to aggregate crisis information from social media and map it to help coordinate response efforts. Events like Crisis Camp and Random Hacks of Kindness bring technologists together to develop open-source tools to help address humanitarian crises. The Haiti earthquake saw many of these collaborative efforts unite to rapidly develop applications and share information to assist response and relief operations.
Presentation delivered by James (Jim) Breaux, PE, MSF, Director, Engineering Operations, Centurion Pipeline Co. at the marcus evans Energy Pipeline Management Summit 2017 held in Dallas, TX
Given the growth of social media and rapid evolution of Web of Data, we have unprecedented opportunities to improve crisis response by extracting social signals, creating spatio-temporal mappings, performing analytics on social and Web of Data, and supporting a variety of applications. Such applications can help provide situational awareness during an emergency, improve preparedness, and assist during the rebuilding/recovery phase of a disaster. Data mining can provide valuable insights to support emergency responders and other stakeholders during crisis. However, there are a number of challenges and existing computing technology may not work in all cases. Therefore, our objective here is to present the characterization of such data mining tasks, and challenges that need further research attention for leveraging social media and Web of Data to assist crisis response coordination.

New media and democratic society 1117 presentationTina Moore
The document discusses new media and democratic society, focusing on crowdsourcing, mashups, and citizen journalism. It provides examples of each: crowdsourcing examples include Ushahidi and OpenStreetMap's mapping of Haiti after the 2010 earthquake. Mashups combine data from different sources, like mapping apartment listings on Craigslist to a map. Citizen journalism allows non-professionals to contribute news reports, like through CNN's iReport or local newspapers that involve citizens. The document examines the trustworthiness of crowdsourced information and how crowdsourcing could impact democracy by giving more voices a platform.
New media and democratic society 1117 presentation2Tina Moore
This document discusses new media and democratic society, focusing on crowdsourcing, mashups, and citizen journalism. It defines crowdsourcing as outsourcing work traditionally done by employees to a large, undefined group. Examples include crowdfunding and crowdvoting. Mashups combine data from multiple sources into a single tool. Citizen journalism allows non-professionals to contribute news reporting. Examples discussed include CNN iReport and Wikinews. While crowdsourcing has potential, issues of trustworthiness and managing biased contributions must be addressed for it to effectively aid democracy.
The document summarizes a social media monitoring activation in response to Typhoon Pablo/Bopha that struck the Philippines in December 2012. It discusses:
1) How Humanity Road and the Standby Volunteer Task Force collaborated over 12 hours to collect over 20,000 social media feeds related to the typhoon, extracting 122 unique reports across 16 categories.
2) The outputs of the activation, which included providing a database to UN OCHA that informed situational reports and was integrated into the Google Crisis Response Map.
3) Expressions of appreciation for the work, including a letter of thanks from UN OCHA for the "job well done" in establishing two-way communication with affected communities.
Offline Activism - How successful activism facilitate social mediaWilson Fung
The document discusses how online activism and social media can facilitate successful offline activism. It provides examples of how the Kony 2012 campaign and Ice Bucket Challenge used social media to raise global awareness and mobilize millions of people. However, clicktivism alone is often not enough and must be backed by real-world actions like protests and meetings with politicians. The Umbrella Movement in Hong Kong also demonstrates how social media allowed protesters to share information in real-time and coordinate their actions despite police presence. For activism to be truly effective, online campaigns need to motivate participants to get involved through offline demonstrations and advocacy.
Three challenges faced by ethical systems in the modern world, and four possible responses to these challenges.

With the explosion in social media (1B+ Facebook users, 500M+ Twitter users) and ubiquitous mobile access (6B+ mobile phone subscribers) sharing their observations and opinions, we have unprecedented opportunities to extract social signals, create spatio-temporal mappings, perform analytics on social data, and support applications that vary from situational awareness during crisis response, preparedness and rebuilding phases to advanced analytics on social data, and gaining valuable insights to support improved decision making.This tutorial weaves three themes and corresponding relevant topics- a.) citizen sensing and crisis mapping, b.) technical challenges and recent research for leveraging citizen sensing to improve crisis response coordination, and c.) experiences in building robust and scalable platforms/systems. It will couple technical insights with identification of computational techniques and algorithms along with real-world examples. We will also do exemplary demos of the features in the Sahana, CrowdMap (Ushahidi's version) and Twitris platforms while elaborating on the practical issues and pitfalls of the development and operation of these large-scale platforms, especially during the real-time crisis response
Public Health Crisis Analytics for Gender ViolenceHemant Purohit
The document discusses using social media data to analyze gender-based violence campaigns and public attitudes. It summarizes a study of cross-campaign participation on Twitter around three hashtags. Most users and tweets were individual rather than organizational. Few male users were observed. The document also describes a system called CitizenHelper for visualizing attitude trend analytics over time from social media to evaluate campaign effects and inform intervention events.

Automatically Rank Social Media Requests for Emergency Services using Service...Hemant Purohit
Public expects a prompt response from online services, including emergency response organizations to requests for help posted on social media. However, the information overload experienced by these organizations, coupled with their limited human resources, challenges them to timely identifying and prioritizing such requests. We present a novel model to formally characterize social media requests and then, develop a Learning-to-Rank system using this model.

Beyond the Bubble: A Critical Review of the Evidence for Echo Chambers and Fi...Axel Bruns
This document provides a critical review of evidence for the existence of echo chambers and filter bubbles. It summarizes that while some case studies have found ideological clustering and selective exposure in social media, broader network mapping and large-scale studies show more complex and interconnected online information networks. It argues that concerns about echo chambers and filter bubbles tend to oversimplify online behavior and overestimate the power of algorithms, when in reality people encounter a diverse range of information online. The real problem, it concludes, is political polarization rather than communicative fragmentation.

The document discusses lessons learned from responding to the 2012 Waldo Canyon Fire using social media and crisis communications. It emphasizes the importance of:
1) Having social media knowledge and tools established beforehand to effectively communicate during emergencies.
2) Regular, timely communication across social media platforms using consistent hashtags and messaging.
3) Engaging with the community and addressing rumors online to provide reliable information.
Open Foreste Italiane - Crisis Camp Europe - Elena Rapisardi
This document summarizes Elena Rapisardi's work on the Open Foreste Italiane project, which used crowdsourcing and geolocated data to support forest fire preparedness and response in Italy. The project started in 2009 by gathering data from forest workers on Facebook. An Ushahidi platform was used to map this data. The project raised awareness of web tools and engaged volunteers, citizens, and institutions. Lessons learned include the need to commit institutions long-term, promote citizen participation, integrate platforms, increase digital literacy, and fundraise. The focus going forward is on preparedness through collaboration at all levels in between emergencies.
Keynote at the Dutch-Belgian Information Retrieval Workshop, November 2016, Delft, Netherlands.
Based on KDD 2016 tutorial with Sara Hajian and Francesco Bonchi.
Bijan Yavar is a research fellow, PhD student, and founder and CEO of MEPCO. The document discusses definitions of risk, emergency, crisis, and disaster from perspectives of both certainty and uncertainty. It provides details on definitions of disaster risk and crisis from various sources. Crisis is defined as a point of change that can have both negative and positive outcomes, while disaster refers to events beyond a community's capacity to respond on its own.
The document describes different study designs for observational studies, including matching designs. It provides two examples of matching designs used to study the effects of hurricanes on online friendships and the effects of exercise on mental health using Twitter data. The hurricane study matched universities affected by a hurricane with unaffected universities on variables like size and ranking. The exercise study matched Twitter users who tweeted about exercising with similar users who did not exercise. The document also discusses using propensity score matching and difference-in-differences to study the effect of having an answer accepted on question answering sites like Stack Overflow.

The document discusses algorithmic bias and fairness in data mining. It is divided into four parts: 1) discrimination discovery, 2) fairness-aware data mining, 3) challenges and future directions, and 4) discussion. It also covers introduction and context, sources of bias, legal concepts, measures of discrimination, specific contexts like labor markets, and the relationship between privacy and discrimination.
This document provides an overview of issues related to crisis management on the internet. It discusses how issues can quickly escalate to crises online due to the speed and reach of information sharing. It emphasizes the importance of monitoring social networks and key influencers, having response plans in place, and being prepared to respond across multiple online channels in a timely manner. Effective crisis response requires understanding normal communications patterns and being able to identify variations that could signal emerging issues. Network analysis and semantic evaluation of online conversations can help with monitoring and issue detection.
2.1 social media in disaster response and preparednessifrcsm4resworkshop
The document discusses how social media and online collaboration can be used for disaster response and preparedness. It provides examples of how social media has been used successfully during disasters to share information, coordinate resources, and find missing people. However, it also notes challenges such as verifying information and filtering out irrelevant posts. Overall, the document argues that social media can improve situational awareness during disasters when tools are in place to identify relevant information in a timely manner.

Transforming Social Big Data into Timely Decisions and Actions for Crisis Mi...Amit Sheth
Keynote @ Exploitation of Social Media for Emergency Relief and Preparedness (SMERP)
Co-located with: The Web Conference 2018 (formerly WWW)
Lyon, France. 23 April 2018
Abstract:
Crises are imposing massive costs to economies worldwide. Natural disasters caused record $306 billion in damage to the U.S. in 2017! Real-time gathering of relevant data through ubiquitous presence of mobile technologies and the ability to disseminate them through social media has forever changed how disaster and health crisis monitoring and response are now carried out. Both tradition crisis response organization as well as temporary, informal, self-organized and community-based organizations have come to increasingly rely on social media. Furthermore, ability to collect, repurpose and reuse data from past events is helping with preparedness and planning for future events.
In this talk, I will review our extensive experience on (a) interactions with variety of stakeholders involved in emergency response at city, county, country and international levels, (b) research on real-time social media analysis spanning spatio-temporal-thematic; people-content-network; linguistic-sentiment-emotion-intent analysis dimensions, (c) development and use of crisis response specific tools (location identification, demand-supply match) and the comprehensive Twitris semantic social intelligence system (which is also commercialized as Cognovi Labs), and (d) a variety of real-world evaluations and real-time uses (e.g., supplying data for Google Crisis map during Uttarakhand Floods, rescue during Kashmir Floods, neighborhood image map during Chennai Floods, providing information to FEMA during Oklahoma tornados), spread of disease and epidemiology (e.g., Zika spread), metro-level multi-agency disaster preparedness exercise, etc.

1) In 2009, leaders needed real-time data to respond to the global economic crisis, but traditional household statistics take years to collect and are outdated for crisis response.
2) New sources of digital data from mobile phone usage, online searches, social media, and other services have the potential to close this information gap and act as "sensors" to detect how vulnerable groups are being impacted in real-time.
3) UN Global Pulse is developing an innovative framework to integrate these new alternative data sources with traditional indicators for real-time crisis monitoring and response at both national and global levels while ensuring privacy, security, and sovereignty.
Social Media Management in Crisis CommunicationDavid Vicent

Memo for the Danish Emergency Management Agency by student Anna Boye Koldaas, Master of Science (MSc)-student in Security Risk Management at Copenhagen University.
This document outlines 10 lessons learned about public communications from the perspective of international humanitarian organizations and NGOs. It discusses how text messages provided key information during disasters when voice networks were down. It also emphasizes the importance of leveraging crowdsourced information from social media and the public, who can often provide more real-time situational updates than agencies. Finally, it encourages identifying plans to collaborate with volunteer groups to amplify messaging and monitor crowdsourced data and discussions.
Evolution of Social Media and its effects on Knowledge OrganisationCollabor8now Ltd
There has been a lot of hype around social media, social networks and social business, much of it unhelpful in understanding what this is all about. For some people, “social” will always mean frivolity and time wasting. For others, social media just means marketing and communications.
The evolution of social media over the past several years has made it easier than ever before to find, connect and engage with “experts” and people with similar interests. Enlightened organisations have recognised that investment in social technologies and (most importantly) the organisational change required in order to nurture and embed a collaborative culture, can overcome the limitations of silo’d structures that have traditionally inhibited information flows and opportunities for innovation.
In a broader context, the pervasive and ubiquitous availability of social media in almost all aspects of daily life, from the way we communicate, get information, buy and sell, travel, live and learn is adding to the pressure on organisations to provide a more porous interface between internal (behind the firewall) and external services. Knowledge workers are increasingly making their own decisions on what tools, products and services that they need to work more effectively and will become increasingly disaffected if these are not available within the work environment.
This presentation looks at industry trends on how social media and social technologies are changing the way that we generate, organise and consume knowledge, and how this is driving emergent digital literacies for knowledge workers.
Statement for the Record of Heather Blanchard, Co Founder of CrisisCommons before the Ad Hoc Subcommittee on Disaster Recovery and Intergovernmental Affairs, Homeland Security and Governmental Affairs Committee, United States Senate on May 19, 2011
This document outlines a presentation on big data for development (BD4D). It discusses the rise of big data and how BD4D techniques like data analytics can be applied. Potential BD4D applications include healthcare, emergency response, and agriculture. Data sources include mobile phones, crowdsourcing, and social media. The presentation also covers BD4D research in Pakistan using mobile data and challenges like data bias, privacy and causation. Open research areas are suggested to further mitigate challenges and advance predictive and multimodal BD4D analytics.

Socia Media and Digital Volunteering in Disaster Management @ DSEM 2017Carlos Castillo (ChaTo)
This document discusses using social media and digital volunteering in disaster management. It outlines how crowdsourcing can be used to extract insights from social media data during disasters through tasks like event detection, content labeling, and quality assessment. However, it notes challenges like biases in the data. The document proposes moving beyond individual insights to develop a "big picture" understanding of disasters. It also suggests moving beyond basic crowd processing to more advanced participatory mining with volunteers. Combining authoritative data with social media and integrating human and machine intelligence are presented as promising approaches.
This document discusses the use of information and communication technologies (ICTs) for risk and crisis management. It provides three aphorisms on wisdom, continuous partial attention, and the diminishing of altruistic response over time. It also discusses challenges including limited coordination, proprietary data formats, and using disaster victims as "lab rats" to test new technologies. Finally, it calls for improved data sharing, interoperability, community-focused technologies, and comprehensive preparedness tools to better leverage ICTs for humanitarian aid.

The tension: Familiar tools vs new uses
●
“In times of disaster and crisis, people tend to gravitate
towards the systems and networks that are most familiar
to them. They shun the specialized sites set up by aid
workers for the comfort of already-established systems
they know well from prior experience.”
●
“Familiar sites for sharing photos of weddings become
locations for sharing breaking news … Participants are using
social web tools in ways the designers of such systems had
neither anticipated nor considered. As a result, the vast
majority of today's technologies are woefully ill-equipped
for crisis situations”
17. 17 BIGCRISISDATA.ORG
Don't do it entirely by hand
● Many tools and systems, some of them free, are available for:
– Organizing your communications with the public through social media
– Monitoring the response of people to social media activity
– Monitoring social media activity
●
You probably don't need “big systems,” but most likely a collection of specialized tools
– Each tool does one job well
– Tools may overlap a bit, sometimes a lot
– If a tool ceases to be relevant, stop using it and find a new one
●
Big tightly-integrated systems bring some comfort but you pay a lot and loose flexibility

Physical and digital convergence
● Disasters involve the convergence of people, resources, and information.
– Some of the people, some of the resources, and some of the information are actually
helpful in the disaster response [Fritz and Mathewson 1975]
●
Social media and mobile phone cameras evaporate traditional scene control [Crowe 2012],
yellow tape does not work so well online
– Note: rescue personnel, including firefighters, police officers, and others who
physically converge on the scene have responsibility and legal codes to respect. As the
public also enters the scene (physically or virtually), they must adhere to ethical
standards they may be unfamiliar with. Technology can be used to weaken or to
strengthen those standards.

Content Credibility
● Internet content is considered as less truthful or valid than other contents
– Reality is more nuanced, otherwise nobody would use Wikipedia or Google
– Are emergency managers used to work with perfect information?
●
Learn to deal with imperfect information, e.g., Admiralty code:
A Reliable
B Usually reliable
C Fairly reliable
D Not usually reliable
E Unreliable
F Cannot be judged
1 Confirmed
2 Probably true
3 Possibly true
4 Doubtfully true
5 Improbable
6 Cannot be judged
34. 34 BIGCRISISDATA.ORG
Crowdsourced tools can also help
One can create tools that
encourage a behavior, e.g.,
we don't want people to
upvote/downvote
content, but instead to
provide evidence.
