Human factors and the WWW : making sense of URLs

We present a study of how WWW users ‘make sense’ of URLs. Experiments were used to investigate users’ capacity to employ the URL as a surrogate for the resource to which it refers. The results show that users can infer useful information from URLs, but that such improvisation has shortcomings as a navigation aid

If you build it, will they come? How researchers perceive and use web 2.0

Over the past 15 years, the web has transformed the way we seek and use information. In the last 5 years in particular a set of innovative techniques – collectively termed ‘web 2.0’ – have enabled people to become producers as well as consumers of information. It has been suggested that these relatively easy-to-use tools, and the behaviours which underpin their use, have enormous potential for scholarly researchers, enabling them to communicate their research and its findings more rapidly, broadly and effectively than ever before. This report is based on a study commissioned by the Research Information Network to investigate whether such aspirations are being realised. It seeks to improve our currently limited understanding of whether, and if so how, researchers are making use of various web 2.0 tools in the course of their work, the factors that encourage or inhibit adoption, and researchers’ attitudes towards web 2.0 and other forms of communication. Context: How researchers communicate their work and their findings varies in different subjects or disciplines, and in different institutional settings. Such differences have a strong influence on how researchers approach the adoption – or not – of new information and communications technologies. It is also important to stress that ‘web 2.0’ encompasses a wide range of interactions between technologies and social practices which allow web users to generate, repurpose and share content with each other. We focus in this study on a range of generic tools – wikis, blogs and some social networking systems – as well as those designed specifically by and for people within the scholarly community. Method: Our study was designed not only to capture current attitudes and patterns of adoption but also to identify researchers’ needs and aspirations, and problems that they encounter. We began with an online survey, which collected information about researchers’ information gathering and dissemination habits and their attitudes towards web 2.0. This was followed by in-depth, semi-structured interviews with a stratified sample of survey respondents to explore in more depth their experience of web 2.0, including perceived barriers as well as drivers to adoption. Finally, we undertook five case studies of web 2.0 services to investigate their development and adoption across different communities and business models. Key findings: Our study indicates that a majority of researchers are making at least occasional use of one or more web 2.0 tools or services for purposes related to their research: for communicating their work; for developing and sustaining networks and collaborations; or for finding out about what others are doing. But frequent or intensive use is rare, and some researchers regard blogs, wikis and other novel forms of communication as a waste of time or even dangerous. In deciding if they will make web 2.0 tools and services part of their everyday practice, the key questions for researchers are the benefits they may secure from doing so, and how it fits with their use of established services. Researchers who use web 2.0 tools and services do not see them as comparable to or substitutes for other channels and means of communication, but as having their own distinctive role for specific purposes and at particular stages of research. And frequent use of one kind of tool does not imply frequent use of others as well

Standardisation and innovation

The paper discusses the relations that exist between standards on the one hand, and innovation and implementation on the other. We will argue that these activities must not be considered separately, especially since standards-based components are going to play an increasingly important role in implementation processes

Pick-n-mix approaches to technology supply : XML as a standard “glue” linking universalised locals

We report on our experiences in a participatory design project to develop ICTs in a hospital ward working with deliberate self-harm patients. This project involves the creation and constant re-creation of sociotechnical ensembles in which XML-related technologies may come to play vital roles. The importance of these technologies arises from the aim underlying the project of creating systems that are shaped in locally meaningful ways but reach beyond their immediate context to gain wider importance. We argue that XML is well placed to play the role of "glue" that binds multiple such systems together. We analyse the implications of localised systems development for technology supply and argue that inscriptions that are evident in XML-related standards are and will be very important for the uptake of XML technologies

Making the Most of Tweet-Inherent Features for Social Spam Detection on Twitter

Social spam produces a great amount of noise on social media services such as Twitter, which reduces the signal-to-noise ratio that both end users and data mining applications observe. Existing techniques on social spam detection have focused primarily on the identification of spam accounts by using extensive historical and network-based data. In this paper we focus on the detection of spam tweets, which optimises the amount of data that needs to be gathered by relying only on tweet-inherent features. This enables the application of the spam detection system to a large set of tweets in a timely fashion, potentially applicable in a real-time or near real-time setting. Using two large hand-labelled datasets of tweets containing spam, we study the suitability of five classification algorithms and four different feature sets to the social spam detection task. Our results show that, by using the limited set of features readily available in a tweet, we can achieve encouraging results which are competitive when compared against existing spammer detection systems that make use of additional, costly user features. Our study is the first that attempts at generalising conclusions on the optimal classifiers and sets of features for social spam detection over different datasets

Political Homophily in Independence Movements: Analysing and Classifying Social Media Users by National Identity

Social media and data mining are increasingly being used to analyse political and societal issues. Here we undertake the classification of social media users as supporting or opposing ongoing independence movements in their territories. Independence movements occur in territories whose citizens have conflicting national identities; users with opposing national identities will then support or oppose the sense of being part of an independent nation that differs from the officially recognised country. We describe a methodology that relies on users' self-reported location to build large-scale datasets for three territories -- Catalonia, the Basque Country and Scotland. An analysis of these datasets shows that homophily plays an important role in determining who people connect with, as users predominantly choose to follow and interact with others from the same national identity. We show that a classifier relying on users' follow networks can achieve accurate, language-independent classification performances ranging from 85% to 97% for the three territories.Comment: Accepted for publication in IEEE Intelligent System

Online platforms of public participation -- a deliberative democracy or a delusion?

Trust and confidence in democratic institutions is at an all-time low. At the same time, many of the complex issues faced by city administrators and politicians remain unresolved. To tackle these concerns, many argue that citizens should, through the use of digital platforms, have greater involvement in decision-making processes. This paper describes research into two such platforms, 'Decide Madrid' and 'Better Reykjavik'. Through the use of interviews, questionnaires, ethnographic observation, and analysis of platform data, the study will determine if these platforms provide greater participation or simply replicate what is already offered by numerous other digital tools. The findings so far suggest that to be successful platforms must take on a form of deliberative democracy, allowing for knowledge co-production and the emergence of collective intelligence. Based on this, we aim to identify key features of sustainable models of online participation.Comment: 8 page

Lost in translation? : negotiating technological innovation in healthcare

Technological innovation in healthcare is growing at a rapid pace. Developments in genetics, stem cell research, bioinformatics, imaging and screening techniques have broadened out the arena of health technology. These developments in sophisticated technology, it is suggested, have the potential to revolutionize the practices of medicine and healthcare by providing more proactive and powerful tools for the diagnosis, treatment, and prevention of illness and disease (Liddell et al, 2008; Webster, 2002). In support of such claims, available research findings suggest that the adoption of new innovative health technologies (IHTs) can result in reducing healthcare costs, increasing productivity, healthcare effectiveness, and improving the patient’s experience of care by better management of chronic diseases (Liddell et al, 2008; Healthcare Industries Task Force, 2004). At the same time, new innovative health technologies present many challenges. Evidence indicates that patient safety and proven clinical effectiveness are insufficient to ensure the adoption and implementation of new clinical technologies. The prevailing organizational and policy context is crucially important as this may present barriers which slow or even prevent uptake (Lehoux 2006). In recent years there has been a continuing debate around issues of clinical resistance, organizational/clinical restructuring, procurement and commissioning, public trust, and, more widely, around the ethical and social implications of techno-scientific innovations in medicine and health (Williams and Dickinson, 2008; Webster, 2006; Ferlie et al., 2005). Moreover, cost-effectiveness evidence is now required to inform decisions about the funding and procurement of new healthcare services and technologies (Fitzgerald et al., 2002). Overall, the value of the innovation has to be clearly evident to a number of different stakeholders if technologies are to be embedded into actual work practices. These potential barriers have given rise to questions related to the diffusion and adoption of emerging medical and healthcare innovations. This paper examines the dynamics and complexity of innovation adoption processes in the context of a rapidly changing healthcare policy landscape. Drawing upon the inherently socially negotiated character of meaning, this paper illustrates the ambivalent nature of technological innovation by examining the complex ongoing interplay of heterogeneous discourses in shaping the adoption of innovative health technologies (Law, 1987, 1994). Drawing upon Rye and Kimberly (2007) adoption is here understood as a distinct organizational process related to an organization’s potential interest in implementing a technological innovation. In so doing, this paper draws on the findings of a three year research project which examines the adoption of innovative clinical technologies in the UK NHS. In particular, we explore the nature, role and dynamics of heterogeneous discourses (technological, managerial/professional, clinical), in shaping the adoption of a retinal imaging technology in a UK hospital Trust. In this regard, we contribute to the development of alternative ways of describing, analysing, and theorizing the process of technological innovation in healthcare

ATHENE : Assistive technologies for healthy living in elders : needs assessment by ethnography

Numerous assistive technologies to support independent living –including personal alarms, mobile phones, self-monitoring devices, mobility aids, software apps and home adaptations –have been developed over the years, but their uptake by older people, especially those from minority ethnic groups, is poor. This paper outlines the ways in which the ATHENE project seeks to redress this situation by producing a richer understanding of the complex and diverse living experiences and care needs of older people and exploring how industry, the NHS, social services and third sector can work with the older people themselves to ‘co-produce’ useful and useable ALT designs to meet their needs. In this paper, we provide an overview of the project methodology and discuss some of the issues it raises for the design and development process

WISC at MediaEval 2017 : multimedia satellite task

This working note describes the work of the WISC team on the Multimedia Satellite Task at MediaEval 2017. We describe the runs that our team submitted to both the DIRSM and FDSI subtasks, as well as our evaluations on the development set. Our results demonstrate high accuracy in the detection of flooded areas from user-generated content in social media. In the first subtask consisting of disaster image retrieval from social media, we found that tags defined by users to describe the images are very helpful for achieving high accuracy classification. In the second subtask consisting of detecting flood in satellite images, we found that social media can increase the precision in analyses when combined with satellite images by taking advantage of spatial and temporal overlaps between data sources
