On 21st of March, we held the HUMANE Intentional Workshop in Oxford. We had some 50+ participants from across different sectors; academia, industry, and public sectors, as well as technicians and freelancers. Among different events and workshops that I have attended in the recent years, I can easily say that our workshop was unique in terms of the wide range of topics, speakers, and attendees.
We started the day with a great keynote by David De Roure from the Oxford e-Research Centre. David spoke about Social Machines and How to Study them. For me, the most thought-provoking part of David’s talk was his call to pay extra attention to the unanticipated and unpredictable outcomes of large assemblies of humans and machines.
We continued with a HUMANE presentation by Asbjørn Følstad, the project co-ordinator from SINTEF. Asbjørn explained how we built the HUMANE Typology and walked us through the HUMANE method. After that, Eric Meyer from the Oxford Internet Institute reviewed the existing literature on Human-Machine networks in a talk titled What’s Humane about Machines?. We closed the morning session with a talk by Vegard Engen of the IT Innovation Centre on Agency in Human-Machine Networks. Vegard’s focus was on the impact of both humans and machines’ agency on trust and user behaviour.
Then we had the lunch break!
We kicked off the afternoon session with a talk by Eva Jaho from ATC Innovation Lab. Eva presented the HUMANE Roadmaps and how they help us to think about the future of human-machine networks. Then we had Grant Miller from Zooniverse to talk about Zooniverse: Humans, Machines, and Penguins; the title tells it all! And finally, just before the coffee break, I presented our work on the edit wars between humans and between bots on Wikipedia.
The last part of the day started with a talk by Brian Pickering, also from IT Innovation Centre. Brian’s talk titled Decision Support for Crowd Management was about the eVACUATE project and how the HUMANE typology and method help us to understand and design better crowd management systems.
Last but not least, Gina Neff, also from the Oxford Internet Institute, presented the other keynote talk of the day titled Making Sense of Self-Tracking Data: Possible futures of the Human-Machine Relationship. Gina introduced self-tracking data as the result of human and machine relationship and then discussed some important aspects of this co-produced outcome: Affordances, Valences, and Symbiotic Agency in relation to the self-tracking data.
Paul Walland (IT Innovation) had the job to summarize the day at the end of the workshop. He not only did this very well, but also sent me a note as a contribution to this wrap-up post. See Paul’s note below, but before that, let me thank all the presenters and the participants again for their contribution to the success of our workshop.
There was a huge range of very interesting stuff presented at the workshop, and it would be both impossible and unfair to try to summarise it all, so I’m not going to do that. What I will do is bring the discussion back to the core objective of the HUMANE project, and think about roadmaps – there are two that occur to me.
One is the technology roadmap – we must not forget that technology is continually advancing, and therefore what people can do with the technology is developing as well. In parallel with this, we have an evolution in what people are trying to do and achieve within networks, which can lead to human capacity increasing, as machines take on the roles that machines do better than people. This is the symbiotic increase in agency that Gina described, reflecting the aspects of agency that introduced in the HUMANE presentations from Vegard and Brian.
The increase in agency – that is the capacity of the machines in the network to take on new roles that might have been the role of a human in the past – liberates the human in the network to focus on achieving their goals without being concerned about the actions the technology is taking to support them. I used to drive rather old MG motor cars. That is to say, I used to spend 90 percent of my time trying to get the motor car to work, and 10 percent of my time coaxing it to get me to where I wanted to go. Now I have a motor car that just works – I don’t need to think about what is going on under the bonnet:- I just get in and drive myself to my destination. But technology continues to advance, and in a few years’ time I won’t need to sit behind a steering wheel and make sure that the motor car follows the road and arrives at a destination, I will simply tell the car where I want to get to and allow it – trust it – to get me where I want to go. My goal hasn’t changed, but the agency, the role taken by the machine, has changed, and in consequence my behaviour has changed to take advantage of the ability to do what I want to do without having to manage or direct the technology that helps me get there.
I am a physicist by background, and my first experience of networks was in the mechanics of how networks are physically assembled and how they transported data. Over the years I have become increasingly interested in the human aspect of networks, since the ultimate goal of technology is to help people achieve their objectives by giving them access to capabilities they do not have without the support of the machines. The two things go hand in hand.
As we have heard from the speakers, serendipitous actions and events can lead to new insights or the emergence of new behaviours. This does not come from machines replacing humans, it comes from humans doing what they do well, and machines doing the things, whether that is fast reaction or massive data crunching, that they can do and humans cannot. It is this cross-cutting of technology and social behaviour/human behaviour that is so interesting and so fruitful. The HUMANE roadmap embraces this interconnectivity of human ambition and machine capability, and I for one am very much looking forward to seeing where it leads.
So I would like to express my thanks to OII and the HUMANE consortium for putting together this fascinating day, and thank all the presenters who have done such a great job of keeping us both entertained and informed.
Three solutions: increased automation, social ties, and extended use of common systems
Crisis management systems (CMS) are human-machine networks consisting of a diversity of actors working together towards achieving the common goal of saving human lives and values. In addition to organizations and people with different capabilities, CMS are important in coping with disastrous events. These systems are meant to support humans in coordinating the handling of an event, and providing information and decision support.
Collaboration is a core requirement for efficient crisis management. The HUMANE typology and framework is helpful in understanding the implications the network’s characteristics have on collaboration. It can provide valuable insight to how to strengthen the design of CMS to better support collaboration and efficient crisis management. The following are three examples.
Increasing machine agency through higher degree of automation
CMS are often intended for use by several crisis response organizations and they are often designed with a high level of human agency and a low level of machine agency. The human actors of the network are given great freedom to configure the system to fit their organization’s needs. The background for this design rational is that the variety of crisis management organizations often have different requirement, thus the system needs to be flexible to fit the needs of all its user organizations.
It can, however, be argued that applying higher degree of automation to certain parts of CMS could streamline human-machine networks for crisis management and make them more efficient. By assigning appropriate tasks to the system, the crisis responders can be given greater leeway to perform tactical or strategic activities, such as planning the handling of an event, making decisions, or other activities that are based on human experience and knowledge and require handling from human actors.
Strengthening the social ties of dispersed human resources
The strength of social ties in crisis management networks varies. The challenge of social ties is especially apparent during handling of a crisis that require the collaboration between several actors and organizations, where social ties are often weak. Knowing the role and authority of one another is an important part of knowing others within crisis management. It is often assumed that a person with a certain work position will handle his or her responsibilities in a sufficient manner. However, weak social ties can sometimes hinder efficient collaboration between people or organizations, as the essential knowledge of and trust in each other is missing.
A well-designed crisis management system has the potential of increasing social ties. By providing a common platform for collaboration, providing information about participating actors and organization, and being a means for information sharing, CMS can strengthen collaboration between crisis responders. In addition, common meeting arenas and training sessions where people across crisis management organizations are trained together, preferably with a common crisis management system, is of high importance for strengthening social ties.
Extending the use of a common crisis management system
There exist a variety of CMS. An issue in today’s crisis management networks is, however, that different crisis management organizations often use different systems that do not support sharing of information, communication, and coordination across the systems. This clearly limits and affects the efficiency of collaboration during management of crisis events. Furthermore, the lack of use among some organizations has implications on the network’s motivation for using the system, which might have implications on the use itself, as users might not see the value of the system when important collaboration partners are absent.
To function as common platform, all relevant crisis management actors should ideally use CMS with possibility of supporting collaboration through joint coordination, communication, and sharing of information. Such system should hold the possibility of integration with other systems.
The introduction of new technology causes concern for the future of work. What is the role of humans in a work life in which an increasing number of tasks are conducted better and more efficiently by machines than by humans.
In a much cited paper on automation of work through computerization, Frey and Osborne, take a starting point in the premise that new technology makes old jobs redundant faster than new jobs are created. They then move on to claim that advances in machine learning and mobile robotics in the 21st century may render not only manual routine work victim to automation, but also work previously thought of as non-routine such as car driving, medical diagnostics, financial trading, or educational tutoring. Think only of the self-driving cars, entities that are able to perform tasks that only a few years back were considered beyond the computational capacities of machines. Tasks that represents engineering bottlenecks for computerizations, such as those associated with perception and manipulation in highly diverse environments, creativity, or social intelligence, are considered low risk for automation also in the foreseeable future. Hence, workers in work that are at risk for automation may need to acquire skills that are not easily automated.
While there is no doubt that automation will replace human workers, the picture may not be as bleak as sometimes suggested in popular reports on the subject. Autor, in an essay on workplace automation, argue that “journalists and even expert commentators tend to overstate the extent of machine substitution for human labor and ignore the strong complementarities between automation and labor that increase productivity, raise earnings, and augment demand for labor”. One example is the technological improvements in the health sector which lead to increasingly larger shares of income being spent on health. Another, is the value creation in the computer industry itself, where automating machinery spawn myriads of previously non-existing jobs.
In HUMANE, we have used the typology dimensions human agency and machine agency as a framework for discussing the role of automation in the complex systems. While Frey and Osborne, as well as Autor, discuss the effect of automation on work at a societal level, we discuss how automation may affect the work of humans within specific human-machine networks. Through a series of case studies on systems for decision support, crisis management, and evacuation support, we investigate how increasing the range of tasks allocated to computerized machines in such settings may actually strengthen the range of tasks, opportunities for influence, and opportunities for creativity in human operators. In these domains, all characterized by highly procedural work tasks and the need to adhere to regulation and policy, allowing machines to take over procedural decision making, human operators may instead spend their time and resources at the tactical and strategical levels of decision making. Here, automation does not remove the need for human operators, but redefines its purpose, allowing for novel ways of value creation.
We often seem to think of automation in terms similar to that of the self-driving cars, where the role of the human driver simply evaporates. The reality, however, may often be that automation enables new forms of value creation where the combined capabilities of humans and machines provide better outcomes in a more efficient manner than was previously possible. By understanding how to design the networked interaction between humans and machines, as we aim for in the HUMANE project, such an optimistic take on the social challenge of automation may be even more feasible.
The HUMANE project is building roadmaps that can help guide future policies in specific social domains such as Sharing Economy, eHealth, and Citizens’ Participation. The HUMANE roadmaps act as a reference on which a collaborative effort for a complex task, such as the one needed for finding and implementing efficient policies for Human-Machine Networks (HMNs), can be based on. It helps all the involved parties recognize the goals and the steps needed for their achievement, and to better understand their roles and interrelations.
Through this Survey we aim to collect information, which we will process and use to develop the HUMANE roadmaps.
The survey shouldn’t take you more than 10-15 minutes to complete. We won’t collect any personal information about you: it is entirely anonymous. Your responses will be used for scientific research purposes only as part of the HUMANE project.
Thank you on behalf of the HUMANE project and we are looking forward to receiving your valuable feedback!
In an excellent cross-cultural study on Wikipedia edit/revert behaviours , Tsvetkova and her colleagues argue among other things for a mediating effect of culture in accounting for different dominance patterns to the editings in different language editions of the online encyclopaedia. The Wikipedia Humane-Machine Network is biased in some sense towards large geographical reach and network size, along with high human agency, low workflow interdependence, but low network organisation. And facebook, as highlighted in a previous post, also displays high human agency, again geographically disparate across a very extensive network. What might these vast networks with a great deal of human agency, but only moderate social tie strength do?
One area that is increasingly brought into focus, however, is cyberbullying . Individuals, especially those in public focus (Jonah Lehrer) or who might be expected to know better (Justine Sacco), may be subjected to the cascading effects of viral relational or indirect aggression in full view of the virtual world (Ronson, 2015 ). The vulnerable and impressionable, such as children, may be subject to grooming as well as aggression, with little chance of refuge , leading to potentially greater affective trauma especially in connection with real-world bullying . Situated within a generalised model of aggression , cyberbullying may be subject to similar social factors  as offline behaviours such as an assumed reluctance to intervene  and a diffusion of responsibility .
Perhaps the reality though, as underlined by the HUMANE profile for these networks, is that network size and geographical dispersion along with high levels of human agency and few controls (low network organisation) lead to what Suler had put down in part to the combination of dissociative anonymity, invisibility and the asynchronic nature of communication and interactions . The perpetrators of online aggression are not easily identifiable, when they hide behind pseudonyms and different online personae, whilst social contagion  creates the domino effect.
We might ask whether increasing Tie strength might mitigate against cyberbullying, by encouraging a shared understanding of its detrimental effects , facilitating participative discussion and understanding  and developing social identity which might encourage protective intervention . Networks with high levels of human agency, as well as large membership and geographic distribution will need to consider carefully how to handle potential problems therefore of latent or weak Tie strength. A number of strategies are possible (see the forthcoming D2.2). But for the unauthorised distribution of personal data and unwanted behaviours outlined here, the risk of not adopting those or similar strategies may be detrimental to the interests or well-being of human participants in the HMN.

In the course of the HUMANE project, we examine a sample of social domains, where human-machine interaction is expected to be significant in the future. We study the type of interactions, the roles of humans and machines, and the challenges that must be addressed to ensure the successful integration of machines in a way that is beneficial for society. We then create a roadmap implementation for each domain that can guide future policies.
We have formalized the HUMANE roadmapping process to be used to construct the roadmap for each social domain where we want to improve Human-Machine Network (HMN) design.
The HUMANE roadmapping process consists of the following steps:

Are users always worried about their data?
One consequence of the Wanless report is a need for more distributed healthcare. This means that an ageing and expanding patient population can be supported at home and in the community. But also not everyone in rural communities will be able to travel any distance for specialist care. This really is the essence of telemedicine or eHealth. So the idea is that ICT can mediate human-to-human (patient-clinician) interaction such that patients can be supported remotely, not least to supplement face-to-face consultation.
A recent pilot study in this area, TRIFoRM, engaged with a small opportunity sample of self-selected patients suffering from a chronic painful condition. Patient-clinician interactions, it was envisaged, would be supplemented by an app that the patients would use to gather daily monitoring data as well as regular self-reports. These would be collated at a central server for clinical staff (consultant, specialist nurse, etc.) to query and review. The idea is that the app running on the patient’s own personal device would supplement their care regime: clinical staff would be able to dispense with asking routine questions about how any exercise regime was going during precious consultation time since this would be available in advance; in so doing, clinicians could devote more time to the patient’s affective state and the holistic effects of the care regime.
Step back for a moment, and consider the data in such a network. It is not just personal data (contact details, for instance) but sensitive personal data (also see See GDPR, Article 9): especially for a chronic condition, worst case is that the data could be used prejudicially to increase insurance premiums or prevent access to certain benefits. Would this affect user trust in the network? As far as the legislative context is concerned, would users be more concerned about their personal data given its defined sensitivity? On one level, perhaps a reflection of the nature of the patients’ condition, technology is a great benefit and takes some of the strain from users. As one participant in a semi-structured interview remarked:
“…if you’re feeling really tired it’s really easy to get brain fog and do something really stupid” ,
which, of course, is a practical illustration of what Norman sees as the main cognitive-support role for machines . In technology acceptance terms, technology is “useful” and so more likely to be adopted, which for Thatcher and his colleagues translates to “helpfulness” and “functionality” in their post adoption trust modelling.
Within this context, the HUMANE profile indicates low human and machine agency: both actor types are restricted in what they can do. But high in terms of tie strength and human-to-machine interaction: human actors rely on the machines to achieve their goals, and rely on each other for the overall efficacy of the care regime. Perhaps not surprisingly given the limited scope for creativity and emergent behaviours, network organisation tends to be high too: there is a top-down structure which limits what can be done. Are these factors which contribute to a more trusting attitude to engaging with the network?
Consider the high tie strength in particular. It turns out there are two main features at least: support to the community of sufferers as well as to the individual’s specific care regime.
“I’m happy to help. It might help me as well but just being part of this community, it’s like let’s all help each other is what I say.”
is one strand which refers to an emergent community of fellow-sufferers both now and in the future who might benefit from the collection and aggregation of such data. The social tie strength in the network then is not simply between patient and clinician, but also to other patients who may not be ‘known’ personally, sharing a common bond with the data subject. If both may benefit, then sensitive personal data can be released. That’s not all though:
“So at those [consultations], it’s not a case of me just reporting and [them] listening to my report let alone what electronic reports might be coming, but it’s the communication. It’s the two-way communication. It’s not just [them] being fed stuff and … going: ‘I don’t need to see you because I’ve got everything here. You can sit there being quiet’ or something” 
Allowing sensitive personal data to be shared in the HMN is about enhancing the tie strength existing between clinician and patient; it’s about enriching the communicative context within a specific dyadic interconnection. In association with strong interactions of this sort, then, data release and data sharing are viewed quite differently.
In a previous post, GDPR and right to be forgotten, weak or latent tie strength may involve serendipitous data access, possibly enhanced through the necessity of physical replication at the carrier level, seems to undermine data subject control over their data. Here, increasing tie strength associated with a specific and very personal goal (immediate care needs as well as long term community benefit) seems to affect data subject willingness to share even sensitive personal data. We should probably look further in future at the aspects of trust and the valence of human-to-human interaction as it affects the management of privacy and trust.

What does HUMANE profiling tell us about data protection?
Back in 1995, the European Parliament issued the Directive for data protection, which by 1998 had passed into national law in the UK. Now, eleven years on and after much consultation such as Working Party 29, in April 2016 the Parliament issued a corresponding regulation – the General Data Protection Regulation (GDPR) – which will automatically pass into law across Member States by May 2018, and will colour the corresponding legislation in non-EU countries wishing to collaborate with the Union. The GDPR harmonises regional and national laws: under the GDPR, for example, registration will be required with a single Data Protection Authority (DPA) in any Member State; a Data Processor now shares liability with the Controller, and may be prosecuted if demonstrably at fault; and, of course, data subjects now have the right to be forgotten (Article 17 ), to a certain extent at least. This is reassuring. And it means that we can all be confident that our personal data are safe. OK, but what happens when those data are released into a human-machine network (HMN)?
Let’s look at a social network, a typical example, of course, being Facebook (see the profile). The network is characterised by its size (“the network has a large or massive number of users…”) and geographical reach (“the network has wide geographical reach, spanning multiple jurisdictions and cultural groups”); human agency is high (“the users to a great degree define their own tasks towards goals they set themselves”); and machine agency (“the behaviour of the machine components in the network to some degree is autonomous and intelligent”) as well as social ties are intermediate (“the users of the network typically have only latent or weak ties, characterized by low levels of intimacy and short duration”). What does the combination of autonomous machine nodes, high human agency, with a highly distributed HMN for the GDPR and the right to erasure?
Tie strength is weak or latent, and so there may be no notion of loyalty or mutual support amongst human actors in the network. Although this is not always the case. In a recent focus group discussion with software engineers in training (to be reported in D3.3), one participant remarked about their use of social media:
“…there are a lot of people that if I was in the same room as them I’d talk to them but messaging them on Facebook would be weird because we’re not that close. That would be strange.”
The assumption here is that facebook is somehow reserved for more private and intimate interactions, which of course the privacy settings might allow if users are prepared to spend time understanding and maintaining them. Alternatively, it may be that the profile dimension represents only an aggregate of all connections between different nodes which may have different roles.
In the context of data privacy, though, this is important. Can users really assume privacy and what is more that they know where their data go and who seems them? Machine agency has been described as “autonomous and intelligent”. One practical outcome not peculiar to social media per se is the common last mile problem (see this for example) in communication networks, the final and often non-optimal link between the backbone network and a retail or private user. One component of a solution where speed is important may be, for instance, to replicate content to a local server. On top of that though, for networks with “wide geographical reach, spanning multiple jurisdictions and cultural group”, content would most clearly be replicated across boundaries, even into different jurisdictions with different laws about personal data. In such an environment, then, demanding that my data be removed as the GDPR seems to promise is almost impossible beyond the safe haven of the EU and its immediate collaborators. Add to this the issue of multiple data sources on an individual being mined and cross-correlated and you have a situation where even the modest requirement for pseudonymisation which the GDPR portrays cannot be guaranteed: with lots of data out there, jigsaw attacks become a real possibility.
The HUMANE profile at least makes it possible to begin to understand the practical implications of reliance on legislation as far as data protection, and specifically the right to be forgotten, are concerned. As one of our focus group participants pointed out when viewing the network diagram created:
“You rarely think about [where the data will go] when you’re like randomly scrolling through things and clicking stuff and things”
This is something that perhaps we as network users should take into account. And in future work, we need to consider how the profile dimensions might highlight implications of the HMN configuration.
 Article 17 Right to erasure (right to be forgotten) is not the blanket mandate which some may assume, but provides some promise that data can be withdrawn if the data subject so wishes.
In recent years, there has been a huge increase in the number of bots online, varying from web crawlers for search engines, to chatbots for online customer service, spambots on social media, and content-editing bots in online collaboration communities.
The online world has turned into an ecosystem of bots. However, our knowledge of how these automated agents are interacting with each other is rather poor. Bots are predictable automatons that do not have the capacity for emotions, meaning-making, creativity, and sociality and it is hence natural to expect interactions between bots to be relatively predictable and uneventful.
We recently posted a new pre-print, in which we analyze the interactions between bots that edit articles on Wikipedia. In the study, we tracked the extent to which bots undid each other’s edits over the period 2001-2010 and on 13 different language editions of the encyclopedia. We modeled how pairs of bots interact over time, and identified different types of interaction trajectories.
Although Wikipedia bots are intended to support the encyclopedia, they often undo each other’s edits and these sterile “fights” may sometimes continue for years. Unlike humans on Wikipedia, bots’ interactions tend to occur over longer periods of time and to be more reciprocated. Yet, just like humans, bots exhibit cultural differences in behavior. For example, bots on German Wikipedia fight less than bots on Portuguese Wikipedia but not because they are different kinds of bots; in fact, they are the same bots but they operate in different kinds of environments.
Our research suggests that even relatively “dumb” bots may give rise to complex interactions, and this carries important implications for Artificial Intelligence research and for the design of human-machine networks. Understanding what affects bot-bot interactions is crucial for managing social media well, providing adequate cyber-security, and designing well functioning autonomous vehicles.
Our study on disagreement in Wikipedia was just published in Scientific Reports (impact factor 5.2). In this study, we find that disagreement and conflict in Wikipedia follow specific patterns. We use complex network methods to identify three kinds of typical negative interactions: an editor confronts another editor repeatedly, an editor confronts back an equally experienced attacker, and less experienced editors confront someone else’s attacker.
Disagreement and conflict are a fact of social life but we do not like to disclose publicly whom we dislike. This poses a challenge for scientists, as we rarely have records of negative social interactions.
To circumvent this problem, we investigate when and with whom Wikipedia users edit articles. We analyze more than 4.6 million edits in 13 different language editions of Wikipedia in the period 2001-2011. We identify when an editor undoes the contribution by another editor and created a network of these “reverts”.
A revert may be intended to improve the content in the article but may also indicate a negative social interaction among the editors involved. To see if the latter is the case, we analyze how often and how fast pairs of reverts occur compared to a null model. The null model removes any individual patterns of activity but preserves important characteristics of the community. It preserves the community structure centered around articles and topics and the natural irregularity of activity due to editors being in the same time zone or due to the occurrence of news-worthy events.
Using this method, we discover that certain interactions occur more often and during shorter time intervals than one would expect from the null model. We find that Wikipedia editors systematically revert the same person, revert back their reverter, and come to defend a reverted editor beyond what would be needed just to improve and maintain the encyclopedia objectively. In addition, we analyze the editors’ status and seniority as measured by the number of article edits they have completed. This reveals that editors with equal status are more likely to respond to reverts and lower-status editors are more likely to revert someone else’s reverter, presumably to make friends and gain some social capital.
We conclude that the discovered interactions demonstrate that social processes interfere with how knowledge is negotiated. Large-scale collaboration by volunteers online provides much of the information we obtain and the software products we use today. The repeated interactions of these volunteers give rise to communities with shared identity and practice. But the social interactions in these communities can in turn affect knowledge production. Such interferences may induce biases and subjectivities into the information we rely on.
