Overview of Social Media During Disaster and Crowd Power in Disaster Response
Prepared for Otago University, COMP113 Social Media and Online
Presented by Catherine Graham
January 29, 2013
This document provides a summary of responses to the Snowden revelations from around the world. It finds that while public perceptions of surveillance have shifted in many countries, tangible reforms have been limited. Two-thirds of experts surveyed reported no significant government measures in response. The UK in particular failed to address issues raised. Media coverage has declined sharply outside the US. Some industry reforms were noted but many experts view them as insufficient. Overall accountability of the global surveillance system remains elusive.
A talk on the rise of digital disaster responders following the Haiti earthquake. Explains the different ways to use the crowds to help out. First to be given in Iceland on October 22nd, 2010.

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.
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.

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.
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.

A Framework to Identify Best Practices: Social Media and Web 2.0 Technologies...Connie White
Social media is used in a variety of domains, including emergency management. However, the question of which technologies are most appropriate for a given emergency remains open. We present a framework of dimensions of emergencies that can assist in selecting appropriate social media for an emergency situation. Social media is not a panacea but can be used effectively given the proper functions available from the particular services provided by each of the Web 2.0 technologies available. The main objective of this paper is to identify the best practices for social media to leverage its ability given the complexities that coincide with events. This is a conceptual paper based on the results of preliminary studies involving group interactions with emergency professionals with various backgrounds. In addition, emergency management students who are professionals in the field followed by another interview soliciting information from information systems scientist were surveyed. We found that each situation called forth various dimensions where only sub phases of the stated dimension may be used given the task type derived from the event characteristics. This lays a foundation upon which a more formal approach can be taken to help tame the social media mania into a manageable set of ‘best practices’ from which emergencies can be managed more effectively given Web 2.0 technologies and social collaborative online tools.

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.
Social Media in Sri Lanka: Do Science and Reason Stand a Chance? - Nalaka Gun...Nalaka Gunawardene
Sri Lanka’s first Science and Technology for Society (STS) Forum took place from 7 to 10 September in Colombo. Organized by the Prime Minister’s Office and the Ministry of Science, Technology and Research, it was one of the largest gatherings of its kind to be hosted by Sri Lanka. http://costi.gov.lk/sts/
Science writer Nalaka Gunawardene was keynote speaker during the session on ‘Using Social Media for Discussing Science Topics’. He used it to highlight how social media have become both a boon and bane for scientific information and thinking in Sri Lanka.
For now, it appears that pseudo-science and anti-science sentiments – some of it rooted in ultra-nationalism or conspiracy theories -- dominate many Lankan social media exchanges. It is as if Lankan society has permanently suspended disbelief.
How and where can the counter-narratives be promoted on behalf of evidenced based, rational discussions? Is this a hopeless task in the face of irrationality engulfing wider Lankan society? Or can progressive and creative use of social media help turn the tide in favour of reason?
Answers to these questions are explored in this presentation, which also cites examples of promising counter-narratives emerging in social media itself. Social media being a contested space, the race between darkness and light continues...
CrisisCampUk: Where next for UK crisis crowdsourcingSara-Jayne Terp
The document discusses the history and current state of crisis crowdsourcing in the UK. It outlines organizations like CrisisCamps and CrisisCommons that have used crowdsourcing tools to help with crises around the world. It argues that the UK is well-positioned to strengthen its crisis information systems and prepare its "crowd" to assist with future crises through these crowdsourcing methods. Specific next steps proposed include connecting UK crisis organizations, maintaining expertise pools, and improving mapping and information tools.

Humanitarian Informatics Approach for Cooperation between Citizens and Organi...Hemant Purohit
This document discusses using a humanitarian informatics approach to facilitate cooperation between citizens and organizational decision makers during crisis situations. It proposes mining and managing social data generated by citizens to address organizations' information needs and challenges of articulation and awareness. Specifically, it involves extracting, classifying, and modeling social data to provide actionable information aligned with organizations' process-driven needs for decision making during disasters and other humanitarian efforts. The approach aims to leverage citizens' massive social media data generation to help organizations that have more defined roles and information needs but less direct access to data.

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.
The document discusses the rise of analytics and use of big data. It provides historical examples of operational research during WWII that helped optimize bomber planes. Today, big data comes from many sources like sensors, social media, and government/business records. Both government and private sector use analytics for applications like transportation optimization, personalized services, fraud detection, and more. However, privacy and security are major challenges as data sharing grows. Developing skills and research institutions can help maximize the benefits of big data while mitigating the risks.
Convergence Partners has released its latest research report on big data and its meaning for Africa. The report argues that big data poses a threat to those it overlooks, namely a large percentage of Africa’s populace, who remain on big data’s periphery.
This document provides an overview of a workshop on using data for science journalism. It discusses several approaches for incorporating data into stories, including: mapping controversies on issues like climate change; using data to tell stories in science and technology; and analyzing networks to reveal connections. Specific techniques are illustrated, such as mapping the influence of climate change skeptics online and connections between counter-jihadist groups on Facebook. The document also reviews several tools and resources for data journalism.
1) The document discusses using Twitter data to analyze the heavy storm that hit the Pukkelpop music festival in Belgium in 2011. It presents analysis of tweets during and after the storm to gain insights into early warnings, damage reports, and community resilience.
2) Key findings include early warnings of the incoming storm 25 minutes before impact, tweets showing damage photos that spread rapidly when posted by trusted sources, and the spontaneous emergence of hashtags like #Hasselthelpt to coordinate relief efforts.
3) Future work could focus on improving methods to verify damage and casualty reports in real-time, assessing credibility of information sources, and developing tools for crisis managers to monitor and respond using social media data.
The document discusses the debate between individual privacy rights and government surveillance efforts aimed at national security. It notes that while increased surveillance can help protect citizens from security threats like terrorism, it may infringe on citizens' privacy rights. The debate centers around finding a balance between these competing interests. The document also mentions how technology has led to more personal information being stored digitally, making it accessible to authorities, and how this issue deeply affects many people given modern technology usage.

Role of Data Accessibility During PandemicDatabricks
This talk focuses on the importance of data access and how crucial it is, to have the granular level of data availability in the open-source space as it helps researchers and data teams to fuel their work.
We present to you the research conducted by the DS4C (Data Science for Covid-19) team who made a huge and detailed level of South Korea Covid-19 data available to a wider community. The DS4C dataset was one of the most impactful datasets on Kaggle with over fifty thousand cumulative downloads and 300 unique contributors. What makes the DS4C dataset so potent is the sheer amount of data collected for each patient. The Korean government has been collecting and releasing patient information with unprecedented levels of detail. The data released includes infected people’s travel routes, the public transport they took, and the medical institutions that are treating them. This extremely fine-grained detail is what makes the DS4C dataset valuable as it makes it easier for researchers and data scientists to identify trends and more evidence to support hypotheses to track down the cause and gain additional insights. We will cover the data challenges, impact that it had on the community by making this data available on a public forum and conclude it with an insightful visual representation.

The document provides information about the World Ethical Data Forum, which examines ethical issues around data use and technology. It discusses the forum's goals of encouraging dialogue between different stakeholders and exploring topics like privacy, surveillance, and artificial intelligence. The summary highlights some key details:
1) The World Ethical Data Forum addresses ethical concerns around data use and encourages collaboration between technology, business, government, and advocacy groups to discuss the implications of data and AI.
2) The first forum was held in Barcelona in 2018 and covered issues like data analytics, privacy, commercial data use, and government surveillance. It featured prominent speakers like Julian Assange.
3) The next conference will be held in London in July 2020 and
The document is a study guide for the Human Rights Council that discusses two topics: the right to privacy in the digital age and addressing the increase in domestic violence. For topic A on the right to privacy, the summary provides background on worldwide surveillance programs like the Five Eyes alliance and how digital technology has impacted privacy. It outlines different bloc positions, with China and Russia expressing concerns about privacy violations and data collection, while the UK and US take different regulatory approaches. The timeline highlights key events in surveillance programs and social media privacy issues.
- Whistleblowing has a long history but contexts have changed with the internet now providing a platform to bypass journalists. However, relying too heavily on platforms like WikiLeaks needs reconsideration.
- There are questions around whether whistleblowers now become the story rather than their actual revelations and risks of smear campaigns against them hiding in full view.
- The context of government secrecy, corporate interests, and erosion of privacy online has arguably made disclosure of wrongdoing more important, but has also enabled closing of information flows and top-down control through consolidation of online platforms.
This document summarizes several articles from the Volta newsletter. It discusses a European project called DESSI that developed a decision-making methodology and online tool to help policymakers choose appropriate security options while considering factors beyond just technology. It also mentions a large-scale citizen consultation in France on energy policy that used the World Wide Views method. Finally, it provides brief updates on upcoming conferences related to science, technology and innovation policy.
The document summarizes an Internet governance webinar on the Internet of Things (IoT). The webinar discussed defining IoT, examples of IoT applications, issues like privacy and security, and the impact of vastly increased data from IoT devices. Speakers explored where adoption of IoT currently stands, from the "hype cycle" perspective, and initiatives by governments and companies to advance IoT technologies and manage their effects.
Whistleblowing and radical transparency on the internet have a long history but changing contexts. While the internet allows bypassing journalists, whistleblowers themselves have become the story through smear campaigns. Maintaining anonymity while revealing information is challenging as governments and corporations work to reassert control over information flows online through market dominance and security policies.

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.
Basic concepts about natural experiments, based mostly on Dunning's book.
