On Publication Usage in a Social Bookmarking System.
In: Proceedings of the 2015 ACM Conference on Web Science,
[Kurzfassung] [BibTeX][Endnote]
Scholarly success is traditionally measured in terms of citations to publications. With the advent of publication man- agement and digital libraries on the web, scholarly usage data has become a target of investigation and new impact metrics computed on such usage data have been proposed – so called altmetrics. In scholarly social bookmarking sys- tems, scientists collect and manage publication meta data and thus reveal their interest in these publications. In this work, we investigate connections between usage metrics and citations, and find posts, exports, and page views of publications to be correlated to citations.

The combination of ubiquitous and social computing is an emerging esearch area which integrates different but complementary methods, echniques and tools. In this paper, we focus on the Ubicon platform, ts applications, and a large spectrum of analysis results. bicon provides an extensible framework for building and hosting applications argeting both ubiquitous and social environments. We summarize the rchitecture and exemplify its implementation using four real-world pplications built on top of Ubicon. In addition, we discuss several cientific experiments in the context of these applications in order o give a better picture of the potential of the framework, and discuss nalysis results using several real-world data sets collected utilizing bicon.

Of course we share! Testing Assumptions about Social Tagging Systems.
[Volltext] [Kurzfassung] [BibTeX]
[Endnote]
Social tagging systems have established themselves as an important part in day's web and have attracted the interest from our research community in a riety of investigations. The overall vision of our community is that simply rough interactions with the system, i.e., through tagging and sharing of sources, users would contribute to building useful semantic structures as ll as resource indexes using uncontrolled vocabulary not only due to the sy-to-use mechanics. Henceforth, a variety of assumptions about social gging systems have emerged, yet testing them has been difficult due to the sence of suitable data. In this work we thoroughly investigate three ailable assumptions - e.g., is a tagging system really social? - by examining ve log data gathered from the real-world public social tagging system bSonomy. Our empirical results indicate that while some of these assumptions ld to a certain extent, other assumptions need to be reflected and viewed in very critical light. Our observations have implications for the design of ture search and other algorithms to better reflect the actual user behavior.

HypTrails: A Bayesian Approach for Comparing Hypotheses about Human Trails on the Web.
[Volltext] [Kurzfassung] [BibTeX]
[Endnote]
When users interact with the Web today, they leave sequential digital trails a massive scale. Examples of such human trails include Web navigation, quences of online restaurant reviews, or online music play lists. derstanding the factors that drive the production of these trails can be eful for e.g., improving underlying network structures, predicting user icks or enhancing recommendations. In this work, we present a general proach called HypTrails for comparing a set of hypotheses about human trails the Web, where hypotheses represent beliefs about transitions between ates. Our approach utilizes Markov chain models with Bayesian inference. The in idea is to incorporate hypotheses as informative Dirichlet priors and to verage the sensitivity of Bayes factors on the prior for comparing hypotheses th each other. For eliciting Dirichlet priors from hypotheses, we present an aption of the so-called (trial) roulette method. We demonstrate the general chanics and applicability of HypTrails by performing experiments with (i) nthetic trails for which we control the mechanisms that have produced them d (ii) empirical trails stemming from different domains including website vigation, business reviews and online music played. Our work expands the pertoire of methods available for studying human trails on the Web.

The information contained in social tagging systems is often modelled as a graph of connections between users, items and tags. Recommendation algorithms such as FolkRank, have the potential to leverage complex relationships in the data, corresponding to multiple hops in the graph. We present an in-depth analysis and evaluation of graph models for social tagging data and propose novel adaptations and extensions of FolkRank to improve tag recommendations. We highlight implicit assumptions made by the widely used folksonomy model, and propose an alternative and more accurate graph-representation of the data. Our extensions of FolkRank address the new item problem by incorporating content data into the algorithm, and significantly improve prediction results on unpruned datasets. Our adaptations address issues in the iterative weight spreading calculation that potentially hinder FolkRank's ability to leverage the deep graph as an information source. Moreover, we evaluate the benefit of considering each deeper level of the graph, and present important insights regarding the characteristics of social tagging data in general. Our results suggest that the base assumption made by conventional weight propagation methods, that closeness in the graph always implies a positive relationship, does not hold for the social tagging domain.

Ubicon: Observing Social and Physical Activities.
In: IEEE International Conference on Cyber, Physical and Social Computing, CPSCom 2012, Besançon, France, 20-23 November, 2012,
Washington, DC, USA.
[Kurzfassung] [BibTeX][Endnote]
The connection of ubiquitous and social computing is an emerging research area which is combining two prominent areas of computer science. In this paper, we tackle this topic from different angles: We describe data mining methods for ubiquitous and social data, specifically focusing on physical and social activities, and provide exemplary analysis results. Furthermore, we give an overview on the Ubicon platform which provides a framework for the creation and hosting of ubiquitous and social applications for diverse tasks and projects. Ubicon features the collection and analysis of both physical and social activities of users for enabling inter-connected applications in ubiquitous and social contexts. We summarize three real-world systems built on top of Ubicon, and exemplarily discuss the according mining and analysis aspects.

The Anatomy of the Facebook Social Graph.
[Volltext] [Kurzfassung] [BibTeX]
[Endnote]
We study the structure of the social graph of active Facebook users, the rgest social network ever analyzed. We compute numerous features of the graph cluding the number of users and friendships, the degree distribution, path ngths, clustering, and mixing patterns. Our results center around three main servations. First, we characterize the global structure of the graph, termining that the social network is nearly fully connected, with 99.91% of dividuals belonging to a single large connected component, and we confirm the ix degrees of separation" phenomenon on a global scale. Second, by studying e average local clustering coefficient and degeneracy of graph neighborhoods, show that while the Facebook graph as a whole is clearly sparse, the graph ighborhoods of users contain surprisingly dense structure. Third, we aracterize the assortativity patterns present in the graph by studying the sic demographic and network properties of users. We observe clear degree sortativity and characterize the extent to which "your friends have more iends than you". Furthermore, we observe a strong effect of age on friendship eferences as well as a globally modular community structure driven by tionality, but we do not find any strong gender homophily. We compare our sults with those from smaller social networks and find mostly, but not tirely, agreement on common structural network characteristics.
