    Jiang, J., Wilson, C., Wang, X., Sha, W., Huang, P., Dai, Y. & Zhao, B.Y. Understanding Latent Interactions in Online Social Networks 2013 ACM Trans. Web
    Vol. 7(4), pp. 18:1-18:39 
    article DOI URL 
    Abstract: Popular online social networks (OSNs) like Facebook and Twitter are changing the way users communicate and interact with the Internet. A deep understanding of user interactions in OSNs can provide important insights into questions of human social behavior and into the design of social platforms and applications. However, recent studies have shown that a majority of user interactions on OSNs are latent interactions, that is, passive actions, such as profile browsing, that cannot be observed by traditional measurement techniques. In this article, we seek a deeper understanding of both active and latent user interactions in OSNs. For quantifiable data on latent user interactions, we perform a detailed measurement study on Renren, the largest OSN in China with more than 220 million users to date. All friendship links in Renren are public, allowing us to exhaustively crawl a connected graph component of 42 million users and 1.66 billion social links in 2009. Renren also keeps detailed, publicly viewable visitor logs for each user profile. We capture detailed histories of profile visits over a period of 90 days for users in the Peking University Renren network and use statistics of profile visits to study issues of user profile popularity, reciprocity of profile visits, and the impact of content updates on user popularity. We find that latent interactions are much more prevalent and frequent than active events, are nonreciprocal in nature, and that profile popularity is correlated with page views of content rather than with quantity of content updates. Finally, we construct latent interaction graphs as models of user browsing behavior and compare their structural properties, evolution, community structure, and mixing times against those of both active interaction graphs and social graphs.

    Vol. 20(1), pp. 53-77 
    article DOI URL 
    Abstract: 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.

    Poelmans, J., Ignatov, D., Viaene, S., Dedene, G. & Kuznetsov, S. Text Mining Scientific Papers: A Survey on FCA-Based Information Retrieval Research 2012
    Vol. 7377Advances in Data Mining. Applications and Theoretical Aspects, pp. 273-287 
    incollection DOI URL 
    Abstract: Formal Concept Analysis (FCA) is an unsupervised clustering technique and many scientific papers are devoted to applying FCA in Information Retrieval (IR) research. We collected 103 papers published between 2003-2009 which mention FCA and information retrieval in the abstract, title or keywords. Using a prototype of our FCA-based toolset CORDIET, we converted the pdf-files containing the papers to plain text, indexed them with Lucene using a thesaurus containing terms related to FCA research and then created the concept lattice shown in this paper. We visualized, analyzed and explored the literature with concept lattices and discovered multiple interesting research streams in IR of which we give an extensive overview. The core contributions of this paper are the innovative application of FCA to the text mining of scientific papers and the survey of the FCA-based IR research.

    Abstract: We propose a system for mining videos from the web for supplementing the content of electronic textbooks in order to enhance their utility. Textbooks are generally organized into sections such that each section explains very few concepts and every concept is primarily explained in one section. Building upon these principles from the education literature and drawing upon the theory of
