A significant portion of today's news articles are part of long running stories. To better understand the context of these stories journalists, social scientists and other scholars use news collections to find temporal and topical insights. However these insights are devoid of user impressions, derived from click-through data and query logs, and are only reliable if the collection is complete and consistent. In this work we introduce the notion of combining user impressions from Wikipedia with news collection based insights for long running news story exploration and outline promising new research directions. We also demonstrate our initial attempts with a prototype system called NewsEX.

Wikipedia, rich in entities and events, is an invaluable resource for various knowledge harvesting, extraction and mining tasks. Numerous resources like DBpedia, YAGO and other knowledge bases are based on extracting entity and event based knowledge from it. Online news, on the other hand, is an authoritative and rich source for emerging entities, events and facts relating to existing entities. In this work, we study the creation of entities in Wikipedia with respect to news by studying how entity and event based information flows from news to Wikipedia. We analyze the lag of Wikipedia (based on the revision history of the English Wikipedia) with 20 years of The New York Times dataset (NYT). We model and analyze the lag of entities and events, namely their first appearance in Wikipedia and in NYT, respectively. In our extensive experimental analysis, we find that almost 20% of the external references in entity pages are news articles encoding the importance of news to Wikipedia. Second, we observe that the entity-based lag follows a normal distribution with a high standard deviation, whereas the lag for news-based events is typically very low. Finally, we find that events are responsible for creation of emergent entities with as many as 12% of the entities mentioned in the event page are created after the creation of the event page.

In this paper, we describe extensions to the process model first described in the paper "From Search to Observation" based on additional field interview work. This process model forms part of a triad of perspectives under the banner of a methodology known as DNA, which looks at structure (Definition), process (Nature) and motivations of actors (Archetypes) for Web Observatories (hereafter WO) and more generally the class of Social Machines. We discuss the rationale for the model enhancements, enumerate and summarise the changes and close with an introduction to future work around use of open source tools and languages for implementing and analyzing social machine processes using this model. The additional perspectives we are now considering are an extensive revision to the model (which now addresses more than three times the number of factors in the previous model) and hence a revised paper is called for in this space.

As the popularity of Twitter, and the volume of tweets increased dramatically, hashtags have naturally evolved to become a de facto context providing/categorizing mechanism on Twitter. Despite their wide-spread adoption, fueled in part by hashtag recommendation systems, lay users continue to generate tweets without hashtags. When such "orphan" tweets show up in a (browsing) user's time-line, it is hard to make sense of their context. In this paper, we present a system called TweetSense which aims to rectify such orphan tweeets by recovering their context in terms of their missing hashtags. TweetSense enables this context recovery by using both the content and social network features of the orphan tweet. We characterize the context recovery problem, present the details of TweetSense and present a systematic evaluation of its effectiveness over a 7 million tweet corpus.

This paper discusses the construction of a Social Machine, a socio-technical system in which people achieve new, creative goals enabled by automated processes that are handled by technology. Specifically, the Social Machine is an online TimeBank, a time-based way for people to give and receive services; it is designed for use in the context of inclusive research (initially) with people with learning disabilities. We describe the use of physical and digital (online) focus groups to gather inputs to drive the construction of the TimeBank, and the processes by which we analysed the data to inform the design of the TimeBank. Our goal is to create an online community with a sense of connectedness, and we discuss this work through that lens, presenting insights gained towards: building the TimeBank itself; methodological implications of related but separate physical and digital focus groups; and building Social Machines.

The Middle-East has witnessed a tremendous increase in Information Warfare Operations on the Web in the last two years. The strategy developed by the ISIS group to increase visibility and reach takes advantage of various core competencies of digital media communication. By identifying actions and observing their impact in the specific context of the Middle East, this ongoing research tries to understand how ISIS conceived its Web communication strategy to target populations and spread its message to the online world.

The emerging practice of using information and communication technologies (ICTs), including the web, SMS, Geographic Information Systems and others, in peacebuilding projects has over the past few years generated growing interest from donors, practitioners and more recently academia. This is in large parts due to three trends: the observed role of new media in conflict situations; the attention given to digital data for conflict analysis, humanitarian and development work; and the emerging use of new forms of ICTs in peacebuilding activities. This interest however leaves implicit the range of constructive contributions ICTs can make to peacebuilding and conflict transformation processes and ways to conceptualise this emerging field. Moreover work undertaken in this area often falls within disciplinary silos that are not conducive to gaining a holistic perspective of the wider implications of using ICTs in peacebuilding contexts. Using an interdisciplinary approach, this paper proposes a framework for understanding some of the constructive contributions ICTs have to make to peacebuilding and conflict transformation processes. Grounded in current debates around the 'liberal peace', this framework allows us to conceptualise ICTs as sociotechnical phenomena, moving beyond ideas of 'solving problems' through technology or a focus on external interventions. Instead the analytical emphasis shifts to the co-evolutive nature of local and other uses of technology, in situations where complex power dynamics are at play, and as such allows us to better understand the technologies' emergent properties, providing a more comprehensive account of their wider societal impacts.

Museum staff tell stories to assist visitor interpretation of artworks. Visitors also tell their own stories to articulate their understanding and opinion of artworks. Additional knowledge about the concepts mentioned or tagged in these stories can be found from online data sources. These could be used to assist reader interpretation or author development of stories. However, the potentially vast network of heterogeneous knowledge that can be created around the tags or annotations of a story could be bewildering for the story reader or author. Here we present Storyscope, a test-bed environment for the authoring, reading and semantic annotation of museum stories. The integration of online knowledge within the task of story authoring or interpretation is facilitated by mapping the available knowledge to a set of facts and simple events related to each story annotation. Narrative principles of theme and setting are used to discover and highlight aspects of the knowledge of potential value to the author or reader. Preliminary studies indicate the potential of the approach for providing a form of semantic navigation across stories and concepts having a better cognitive fit to story related tasks than existing forms of navigation.

Decision makers depend on socio-economic indicators to shape the world we inhabit. Reports of these indicators are often delayed due to the effort involved in gathering and aggregating the underlying data. Our increasing interactions with large scale technological systems are generating vast datasets on global human behaviour which are immediately accessible. Here we analyse whether data on how often people view Wikipedia articles might help us to improve estimates of the current number of tourists leaving the UK. Our analyses suggest that in the absence of sufficient history, Wikipedia page views provide an advantage. We conclude that when using adaptive models, Wikipedia usage opens up the possibility to improve estimates of tourism demand.

This article asks why engineers building robots should consider privacy aspects when programming their gadgets. We start with a definition of robots, differentiating active, social robots from passive, non-social robots. We then discuss the related literature on the privacy implications of social robots. Two aspects are of fundamental concern in this context: the pervasiveness and intrusiveness of robots on the one hand and a general lack of awareness and knowledge about how robots work, collect and process sensitive data on the other hand. We explain how the existing literature on robot ethics provides a suitable framework to address these two issues. In particular, robot ethics are useful to point out how engineers' and regulators' mindset towards privacy protection differs. The paper argues that different -- at first sight incommensurable -- rationalities exist when it comes to robotic privacy. As a contribution to the emerging field of robotic privacy, we propose an interdisciplinary and collaborative approach that bridges the two rationalities. This approach considers the role of code as the central governing element of robots. RoboCode-Ethicists, trans-disciplinary experts trained in the technical/computational, legal and social aspects of robotics, should lead the way in the discussion on robotic privacy. They could mediate between different stakeholders -- mainly regulators, users and engineers -- and address emerging privacy issues as early as possible.
