It was the third costliest insurance event in history. The CEISMIC archive developed at the University of Canterbury will soon have collected almost 100,000 digital objects documenting the experiences of the people and communities affected by the earthquake, all of it available for study.

The Internet can be hugely useful to coordinate disaster relief efforts, or to help rebuild affected communities. Paul Millar came to the OII on 21 May 2012 to discuss the CEISMIC archive project and the role of digital humanities after a major disaster (below). We talked to him afterwards.

Ed: You have collected a huge amount of information about the earthquake and people’s experiences that would otherwise have been lost: how do you think it will be used?

Paul: From the beginning I was determined to avoid being prescriptive about eventual uses. The secret of our success has been to stick to the principles of open data, open access and collaboration — the more content we can collect, the better chance future generations have to understand and draw conclusions from our experiences, behaviour and decisions. We have already assisted a number of research projects in public health, the social and physical sciences; even accounting. One of my colleagues reads balance sheets the way I read novels, and discovers all sorts of earthquake-related signs of cause and effect in them. I’d never have envisaged such a use for the archive. We have made our ontology is as detailed and flexible as possible in order to help with re-purposing of primary material: we currently use three layers of metadata — machine generated, human-curated and crowd sourced. We also intend to work more seriously on our GIS capabilities.

Ed: How do you go about preserving this information during a period of tremendous stress and chaos? Was it difficult to convince people of the importance of this longer-term view?

Paul: There was no difficulty convincing people of the importance of what we were doing: everyone got it immediately. However, the scope of this disaster is difficult to comprehend, even for those of us who live with it every day. We’ve lost a lot of material already, and we’re losing more everyday. Our major telecommunications provider recently switched off its CDMA network — all those redundant phones are gone, and with them any earthquake pictures or texts that might have been stored. One of the things I’d encourage every community to do now is make an effort to preserve key information against a day of disaster. If we’d digitised all our architectural plans of heritage buildings and linked them electronically to building reports and engineering assessments, we might have saved more.

Ed: It seems obvious in hindsight that the Internet can (and should be) be tremendously useful in the event of this sort of disaster: how do we ensure that best use is made?

Paul: The first thing is to be prepared, even in a low-key way, for whatever might happen. Good decision-making during a disaster requires accurate, accessible, and comprehensive data: digitisation and data linking are key activities in the creation of such a resource — and robust processes to ensure that information is of high quality are vital. One of the reasons CEISMIC works is because it is a federated archive — an ideal model for this sort of event — and we were able to roll it out extremely quickly. We could also harness online expert communities, crowd-sourcing efforts, open sourcing of planning processes, and robust vetting of information and auditing of outcomes. A lot of this needs to be done before a disaster strikes, though. For years I’ve encountered the mantra ‘we support research but we don’t fund databases’. We had to build CEISMIC because there was no equivalent, off-the-shelf product — but that development process lost us a year at least.

Ed: What equivalent efforts are there to preserve information about major disasters?

Paul: The obvious ones are the world-leading projects out of Center for History and New Media at George Mason University, including their 9/11 Digital Archive. One problem for any archive of this nature is that information doesn’t exist in a free and unmediated space. For example, the only full record of the pre-quake Christchurch cityscape is historic Google Street View; one of the most immediate sources of quake information was Twitter; many people communicated with the world via Facebook, and so on. It’s a question we’re all engaging with: who owns that information? How will it be preserved and accessed? We’ve had a lot of interest in what we are doing, and plenty of consultation and discussion with groups who see our model as being of some relevance to them. The UC CEISMIC project is essentially a proof of concept — versions of it could be rolled out around the world and left to tick over in the background, quietly accumulating material in the event that it is needed one day. That’s a small cost alongside losing a community’s heritage.

Ed: What difficulties have you encountered in setting up the archive?

Paul: Where do I start? There were the personal difficulties — my home damaged, my family traumatised, the university damaged, staff and students all struggling in different ways to cope: it’s not the ideal environment to try and introduce a major IT project. But I felt I had to do something, partly as a therapeutic response. I saw my engineering and geosciences colleagues at the front of the disaster, explaining what was happening, helping to provide context and even reassurance. For quite a while I wondered what on earth a professor of literature could do. It was James Smithies – now CEISMIC’s Project Manager – who reminded me of the 9/11 Archive. The difficulties we’ve encountered since have been those that beset most under-resourced projects — trying to build a million dollar project on a much smaller budget. A lot of the future development will be funding dependent, so much of my job will be getting the word out and looking for sponsors, supporters and partners. But although we’re understaffed, over-worked and living in a shaky city, the resilience, courage, humanity and good will of so many people never ceases to amaze and hearten me.

Ed: Your own research area is English Literature: has that had any influence on the sorts of content that have been collected, or your own personal responses to it?

Paul: My interest in digital archiving started when teaching New Zealand Literature at Victoria University of Wellington. In a country this small most books have a single print run of a few hundred; and even our best writers are lucky to have a text make it to a second edition. I therefore encountered the problem that many of the texts I wanted to prescribe were out of print: digitisation seemed like a good solution. In New Zealand the digital age has negated distance — the biggest factor preventing us from immediate and meaningful engagement with the rest of the world. CEISMIC actually started life as an acronym (the Canterbury Earthquakes Images, Stories and Media Integrated Collection), and the fact that ‘stories’ sits centrally certainly represents my own interest in the way we use narratives to make sense of experience. Everyone who went through the earthquakes has a story, and every story is different. I’m fascinated by the way a collective catastrophe becomes so much more meaningful when it is broken down into individual narratives. Ironically, despite the importance of this project to me, I find the earthquakes extremely difficult to write about in any personal or creative way. I haven’t written my own earthquake story yet.

Slicing digital data: methodological challenges in computational social science https://ensr.oii.ox.ac.uk/slicing-digital-data-methodological-challenges-in-computational-social-science/ Wed, 30 May 2012 10:45:26 +0000 http://blogs.oii.ox.ac.uk/policy/?p=337 One of the big social science questions is how our individual actions aggregate into collective patterns of behaviour (think crowds, riots, and revolutions). This question has so far been difficult to tackle due to a lack of appropriate data, and the complexity of the relationship between the individual and the collective. Digital trails are allowing Social Scientists to understand this relationship better.

Small changes in individual actions can have large effects at the aggregate level; this opens up the potential for drawing incorrect conclusions about generative mechanisms when only aggregated patterns are analysed, as Schelling aimed to show in his classic example of racial segregation. 

Part of the reason why it has been so difficult to explore this connection between the individual and the collective — and the unintended consequences that arise from that connection — is lack of proper empirical data, particularly around the structure of interdependence that links individual actions. This relational information is what digital data is now providing; however, they present some new challenges to the social scientist, particularly those who are used to working with smaller, cross-sectional datasets. Suddenly, we can track and analyse the interactions of thousands (if not millions) of people with a time resolution that can go down to the second. The question is how to best aggregate that data and deal with the time dimension.

Interactions take place in continuous time; however, most digital interactions are recorded as events (i.e. sending or receiving messages), and different network structures emerge when those events are aggregated according to different windows (i.e. days, weeks, months). We still don’t have systematic knowledge on how transforming continuous data into discrete observation windows affects the networks of interaction we analyse. Reconstructing interpersonal networks (particularly longitudinal network data) used to be extremely time consuming and difficult; now it is relatively easy to obtain that sort of network data, but modelling and analysing them is still a challenge.

Another problem faced by social scientists using digital data is that most social networks are multiplex in nature, that is, we belong to many different networks that interact and affect each other by means of feedback effects: How do all these different network structures co-evolve? If we only focus on one network, such as Twitter, we lose information about how activity in other networks (like Facebook, or email, or offline communication) is related to changes in the network we observe. In our study on the Spanish protests, we only track part of the relevant activity: we have a good idea of what was happening on Twitter, but there were obviously lots of other communication networks simultaneously having an influence on people’s behaviour. And while it is exciting as a social scientist to be able to access and analyse huge quantities of detailed data about social movements as they happen, the Twitter network only provides part of the picture.

Finally, when analysing the cascading effects of individual actions there is also the challenge of separating out the effects of social influence and self-selection. Digital data allow us to follow cascading behaviour with better time resolution, but the observational data usually does not help discriminate if people behave similarly because they influence and follow each other or because they share similar attributes and motivations. Social scientists need to find ways of controlling for this self-selection in online networks; although digital data often lacks the demographic information that allows applying this control, digital technologies are also helping researchers conduct experiments that help them pin down the effects of social influence.

Digital data is allowing social scientists pose questions that couldn’t be answered before. However, there are many methodological challenges that need solving. This talk considers a few, emphasising that strong theoretical motivations should still direct the questions we pose to digital data.

Internet, Politics, Policy 2010: Closing keynote by Viktor Mayer-Schönberger https://ensr.oii.ox.ac.uk/internet-politics-policy-2010-closing-keynote-by-viktor-mayer-schonberger/ Fri, 17 Sep 2010 15:48:04 +0000 http://blogs.oii.ox.ac.uk/policy/?p=94 Our two-day conference is coming to a close with a keynote by Viktor Mayer-Schönberger who is soon to be joining the faculty of the Oxford Internet Institute as Professor of Internet Governance and Regulation.

Viktor talked about the theme of his recent book“Delete: The Virtue of Forgetting in the Digital Age”(a webcast of this keynote will be available soon on the OII website but you can also listen to a previous talk here). It touches on many of the recent debates about information that has been published on the web in some context and which might suddenly come back to us in a completely different context, e.g. when applying for a job and being confronted with some drunken picture of us obtained from Facebook.

Viktor puts that into a broad perspective, contrasting the two themes of “forgetting” and “remembering”. He convincingly argues how for most of human history, forgetting has been the default. This state of affairs has experienced quite a dramatic change with the advances of the computer technology, data storage and information retrieval technologies available on a global information infrastructure.  Now remembering is the default as most of the information stored digitally is available forever and in multiple places.

What he sees at stake is power because of the permanent threat of our activities are being watched by others – not necessarily now but possibly even in the future – can result in altering our behaviour today. What is more, he says that without forgetting it is hard for us to forgive as we deny us and others the possibility to change.

No matter to what degree you are prepared to follow the argument, the most intriguing question is how the current state of remembering could be changed to forgetting. Viktor discusses a number of ideas that pose no real solution:

  1. privacy rights – don’t go very far in changing actual behaviour
  2. information ecology – the idea to store only as much as necessary
  3. digital abstinence – just not using these digital tools but this is not very practical
  4. full contextualization – store as much information as possible in order to provide necessary context for evaluating the informations from the past
  5. cognitive adjustments – humans have to change in order to learn how to discard the information but this is very difficult
  6. privacy digital rights management – requires the need to create a global infrastructure that would create more threats than solutions

Instead Viktor wants to establish mechanisms that ease forgetting, primarily by making it a little bit more difficult to remember. Ideas include

  • expiration date for information, less in order to technically force deletion but to socially force thinking about forgetting
  • making older information a bit more difficult to retrieve

Whatever the actual tool, the default should be forgetting and to prompt its users to reflect and choose about just how long a certain piece of information should be valid.

Nice closing statement: “Let us remember to forget!

Internet, Politics, Policy 2010: What is our impact on the Internet? Keynote by Arthur Lupia https://ensr.oii.ox.ac.uk/internet-politics-policy-2010-what-is-our-impact-on-the-internet-keynote-by-arthur-lupia/ Thu, 16 Sep 2010 11:53:49 +0000 http://blogs.oii.ox.ac.uk/policy/?p=103 Arthur Lupia has just been delivering the opening keynote on our very own conference “Internet, Politics, Policy 2010: An Impact Assessment” here in Oxford. He started by turning on the audience:

  • What is our impact on the Internet?
  • Have we been as effective as we could have been in changing people’s beliefs and behaviours?

However, this wasn’t about benchmarking success of researchers into Internet and Politics but about the question why many well-intentioned projects – be it making people participate in politics, be getting across the relevance of your ground-breaking research or whatever – ultimately fail.

Arthur Lupia’s main argument that many of these well-meant enterprises do not take into account sufficiently how people are. How they are is – according to Lupia – mainly defined by three broad influences:

  1. biology
  2. social behaviour (e.g. how we learn etc)
  3. political contexts

So in order to successfully persuade others (in any benign meaning of course) he posits three necessary conditions (implying that they might not be sufficient):

  1. attention: as people have a limited capacity to pay attention, your message will only get through if they feel its urgency and relevance for them
  2. elaboration: relate your message to the audience. People will only listen if it is unique and highly relevant to them. Ways to achieve this is by making it local, concrete and immediate but also by making the desired change possible, making clear that the desired effect is within reach
  3. credibility:  Finally, credibility is key but this is not an absolute value but it is domain-specific. Credibility is bestowed on someone by the audience and depends on whether the audience believes (not matter if correctly) that you are knowledgeable and share their interests
